The <tt>tp_smapi</tt> kernel module exposes some features of the ThinkPad hardware/firmware via a <tt>sysfs</tt> interface. Currently, the main implemented functionality is control of battery charging and extended battery status. The tp_smapi software package also includes an improved version of the [[HDAPS]] driver. The underlying hardware interfaces are [[SMAPI support for Linux|SMAPI]] and direct access to the embedded controller.

This driver uses undocumented features and direct hardware access, so it may work unreliably or even damage your hardware; but so far no such damage has been reported.

===Features===
*<tt>tp_smapi</tt> driver
**Battery charge/discharge control
**Battery status information
*<tt>hdaps</tt> driver (compared with the standard <tt>hdaps</tt> driver)
**Improved stability
**Improved model support
**Improved functionality

===Project Homepage / Availability===
* Project page: http://tpctl.sourceforge.net/
* Download page: http://sourceforge.net/projects/tpctl/files/tp_smapi
* You need to download only the tp_smapi package.

===Installation===
====Installation from source====
You will need the kernel headers and makefiles corresponding to your current kernel version. On {{Fedora}}, this means {{cmdroot|yum install kernel-devel-$(uname -r)}} .

:{{cmdroot|tar xzvf tp_smapi-0.40.tgz}}
:{{cmdroot|cd tp_smapi-0.40}}

Then, either compile and load the driver within the current working directory (for testing):
:{{cmdroot|make load}}
OR compile and install into the kernel's module path:
:{{cmdroot|make install}}

If you use the [[HDAPS]] driver, add <tt>HDAPS=1</tt> to also patch the <tt>hdaps</tt> for compatibility with <tt>tp_smapi</tt> (this requires a kernel source tree matching the current kernel).
Again, either load the driver within the current working directory:
:{{cmdroot|1=make load HDAPS=1}}
OR install into the kernel's module path:
:{{cmdroot|1=make install HDAPS=1}}

To prepare a stand-alone patch against the current kernel tree (including
a patch against <tt>hdaps</tt> and new <tt>Kconfig</tt> entries):
:{{cmdroot|make patch}}

To delete all autogenerated files:
:{{cmdroot|make clean}}

The original kernel tree is never modified by any these commands.
The {{path|/lib/modules}} directory is modified only by {{cmdroot|make install}}.

====Installation in Gentoo====
The {{Gentoo}} portage system carries a [http://packages.gentoo.org/package/app-laptop/tp_smapi tp_smapi package], which follows the latest version pretty closely. On a Gentoo system, you can install and load as follows.

If you use the [[HDAPS]] driver, do this first:

* Disable the <tt>hdaps</tt> module in your kernel configuration (Device Drivers → Hardware Monitoring Support → IBM Hard Drive Active Protection System)
* Rebuild and install the kernel
* Add the <tt>hdaps</tt> use flag in {{path|/etc/make.conf}}
* {{cmdroot|rmmod hdaps}}

Then:
* {{cmdroot|emerge tp_smapi}} (or install tp_smapi with hdaps support manually, as above)
* {{cmdroot|echo "tp_smapi" >> /etc/modules.autoload.d/kernel-2.6}}
* {{cmdroot|echo "hdaps" >> /etc/modules.autoload.d/kernel-2.6}}

Then reboot, or run:
* {{cmdroot|modprobe tp_smapi}}
* {{cmdroot|modprobe hdaps}}

'''NOTE:''' If {{cmdroot|modprobe}} fails and dmesg says something about <tt>__stack_chk_fail()</tt>, you probably just compiled your modules with <tt>-fstack-protector</tt> and/or <tt>-fstack-protector-all</tt> without having a kernel that supports it. You can either configure your kernel to have <tt>CC_STACKPROTECTOR</tt> enabled (in ''Processor type and features'' if you use {{cmdroot|make menuconfig}}) or edit your <tt>make.conf</tt> (or, if you're using paludis, your <tt>/etc/paludis/bashrc</tt>) and remove <tt>-fstack-protector</tt> and <tt>-fstack-protector-all</tt> from your <tt>CFLAGS</tt>. If you choose to enable it in the kernel, be aware that you need a patched GCC for it (and I do not know if the gcc in stage3 is patched).

====Installation on Debian unstable (sid), testing (squeeze) or stable (lenny)====
Debian now contains the [http://packages.debian.org/tp-smapi packaged module source] and prebuilt modules for Debian kernels.

If you use a stock Debian kernel, you can install the tp_smapi modules with:
* {{cmdroot|apt-get install tp-smapi-modules-`uname -r`}}
* in order to make sure the modules package is kept in sync with the kernel one, you may also want to install the <code>tm-smapi-modules-2.6-686</code> or <code>tm-smapi-modules-2.6-amd64</code> package, depending on your architecture

If you use a custom kernel, you can build tp_smapi with module-assistant:
* {{cmdroot|aptitude install tp-smapi-source}}
* {{cmdroot|m-a -t a-i tp-smapi}}

====Installation on Debian unstable (sid) or testing (squeeze) (kernel >=2.6.32-5)====
You can use 'dkms' on Debian unstable (sid) or testing (squeeze) (kernel >=2.6.32-5) (Note: If installation seems ineffective, confirm your have the linux-headers of your kernel installed, purge tp-smapi-dkms and reinstall.)
* {{cmdroot|aptitude install tp-smapi-dkms}}

====Installation on openSUSE====
openSUSE provides rpm packages. Look for them at the package search: [http://software.opensuse.org/search/], search for the package named "tp_smapi".

A step-by-step guide on how a relative linux newbie installed tp_smapi on a Thinkpad W500 running openSuse 11.1 using YAST Software Manager is available [http://forums.opensuse.org/hardware/laptop/417254-tp_smapi-lenovo-thinkpad-t400-t500-w500-step-step.html#post2005932 here]

In case you are taking the hard way around, while compiling on 11.0, make complained about not being able to locate the kernel sources. It worked for me after I did this:
<pre><nowiki>cp /usr/include/linux/aio_abi.h /lib/modules/`uname -r`/build/include/linux/</nowiki></pre>

====Installation on Ubuntu====
Ubuntu ships tp_smapi in their <tt>linux-ubuntu-modules-*</tt> package for Hardy, so you don't have to build it yourself. Please note that they have renamed tp_smapi's modified <tt>hdaps</tt> module to <tt>hdaps_ec</tt> so that the two can coexist. You should load <tt>hdaps_ec</tt>, not <tt>hdaps</tt>.

Ubuntu Intrepid and Jaunty, however, lack the <tt>hdaps_ec</tt> module, as reported [https://bugs.launchpad.net/ubuntu/+source/linux/+bug/297213 here]. It will not be included again until said [[#Bundled hdaps driver|bundled hdaps driver]] is merged into mainline.

=====Installation on Ubuntu Jaunty=====
I have posted my experiences [http://meandmyubuntu.blogspot.com/2009/05/getting-hdasp-to-work-on-jaunty.html here]

=====Installation on Ubuntu Karmic=====
Ubuntu does not ship the precompiled module tp_smapi any more. However the source code is still present in the repository. It can be installed through module-assistant :
:{{cmdroot|aptitude install tp-smapi-source}}
:{{cmdroot|module-assistant prepare tp-smapi}}
:{{cmdroot|module-assistant auto-install tp-smapi}}
:{{cmdroot|modprobe tp-smapi}}

=====Installation on Ubuntu Lucid=====
The Karmic solution above works well.

As an alternative, one can use the dkms flavour of the packages via
:{{cmdroot|aptitude install tp-smapi-dkms}}
:{{cmdroot|modprobe tp_smapi}}

{{HINT|This appears to be the ideal solution. A description of DKMS, from [http://linux.dell.com/projects.shtml#dkms Dell]: "DKMS stands for Dynamic Kernel Module Support. It is designed to create a framework where kernel dependent module source can reside so that it is very easy to rebuild modules as you upgrade kernels."}}

====Installation on older Ubuntu/Debian====
Installation on Ubuntu or Debian is quite easy, but there are a few things to look after:

To get your system ready for compiling code, install the build-essentials (as root, of course, as all of the following comands; Ubuntu users have to prepend 'sudo' to every line and enter their own password when prompted):
<pre><nowiki>apt-get install build-essential</nowiki></pre>

To get tp_smapi to work, obtain the latest source as mentioned above and unpack it. If you want to use HDAPS, you need to install the kernel source matching te kernel you are running. To do so, issue this:
<pre><nowiki>uname -r</nowiki></pre>
This will give you the version of your current kernel.
Debian users execute the following:
<pre><nowiki>apt-get install linux-source-`uname -r`</nowiki></pre>
Ubuntu users execute the following using the kernel-version only (exclude -XX-generic; e.g. 'linux-source-2.6.20'):
<pre><nowiki>apt-get install linux-source-`uname -r`</nowiki></pre>

Be sure to unpack the source file. The easiest way is to open Nautilus as root:
<pre><nowiki>sudo nautilus</nowiki></pre>
Then browse to /usr/src/ and extract the source file to that directory.

Now change to the tp_smapi dir:
<pre><nowiki>cd tp_smapi-X.YY</nowiki></pre> (X.YY being the version-number of [[tp_smapi]])
and make and install tp_smapi as instructed above.

If you get an error that the kernel version isn't matching (or that you need to set KSRC/KBUILD), please check that there is a symlink from the modules dir to the kernel source:
<pre><nowiki>root@localhost:~#ls -l /lib/modules/2.6.20-16-generic
lrwxrwxrwx 1 root root 28 2007-02-02 08:39 build -> /usr/src/linux-source-2.6.20</nowiki></pre>
Create the link if the line above does not exist:
<pre><nowiki>root@localhost:~#ln -s /usr/src/linux-source-2.6.20 /lib/modules/2.6.20-16-generic/build</nowiki></pre>

Now the following will build and install the correct modules to their locations:
<pre><nowiki>make install HDAPS=1</nowiki></pre>
To make sure your system loads the modules at boot time, do this:
<pre><nowiki>echo "tp_smapi" >> /etc/modules
echo "hdaps" >> /etc/modules</nowiki></pre>
and update your initramfs:
<pre><nowiki>update-initramfs -u</nowiki></pre>

To get tp_smapi running now, just load the modules:
<pre><nowiki>modprobe -a tp_smapi hdaps</nowiki></pre>

This description was tested on Kubuntu 'Feisty Fawn' and should work on all Debian-based distros with minor tweaks.

'''EDIT:''' Works on Kubuntu 7.10 ("Gutsy Gibbon"), too

===Battery charge control features===
{{NOTE|Not all Thinkpad ECs support these charge control features. If you get the message "Operation not supported" when trying to cat for the status of a given parameter, it means your controller does not support that feature.}}

To set the thresholds for starting and stopping battery charging (in percent of current full charge capacity):
:{{cmdroot|echo 40 > /sys/devices/platform/smapi/BAT0/start_charge_thresh}}
:{{cmdroot|echo 70 > /sys/devices/platform/smapi/BAT0/stop_charge_thresh}}
:{{cmdroot|cat /sys/devices/platform/smapi/BAT0/*_charge_thresh}}
{{HINT|Battery charging thresholds can be used to keep Li-Ion and Li-Polymer batteries partially charged, in order to [[Maintenance#Battery_treatment|increase their lifetime]].}}
To prevent charging for 17 minutes (regardless of thresholds):
:{{cmdroot|echo 17 > /sys/devices/platform/smapi/BAT0/inhibit_charge_minutes}}
{{HINT|Charge inhibiting can be used to reduce the power draw of the laptop, in order to use an under-spec power supply that can't handle the combined power draw of running and charging. It can also be used to control which battery is charged when [[How to use UltraBay batteries|using an Ultrabay battery]].}}

To cancel charging preventation:
:{{cmdroot|echo 0 > /sys/devices/platform/smapi/BAT0/inhibit_charge_minutes}}

To force battery discharging (even if connected to AC):
:{{cmdroot|echo 1 > /sys/devices/platform/smapi/BAT0/force_discharge}}
{{HINT|This can be used to choose which battery is discharged when [[How to use UltraBay batteries|using an UltraBay battery]]. For example, see the {{CodeRef|tp-bat-balance}} script.}}

To cancel forced discharge:
:{{cmdroot|echo 0 > /sys/devices/platform/smapi/BAT0/force_discharge}}

====Making the settings permanent on reboot====

If you always use the same type of battery, then you may want the same settings to be configured each time you boot the machine.

If you use various types of battery, then you may want to consider writing some scripts to detect the battery type and apply the appropriate settings.

=====Debian=====

It is not necessary to create your own init.d script or modify /etc/rc.local - you just need the package sysfsutils:
:{{cmdroot|apt-get install sysfsutils}}

Now, put your desired settings in /etc/sysfs.conf:

<pre><nowiki># cat >> /etc/sysfs.conf << EOF
# For a LiIon battery in a Thinkpad
devices/platform/smapi/BAT0/start_charge_thresh = 50
devices/platform/smapi/BAT0/stop_charge_thresh = 80
EOF</nowiki></pre>

The init script supplied by sysfsutils will load these settings on each boot.

===Battery status features===
To view extended battery status such as charging state, voltage, current, capacity, cycle count and model information:

<pre>
# cat /sys/devices/platform/smapi/BAT0/installed
# cat /sys/devices/platform/smapi/BAT0/state # idle/charging/discharging
# cat /sys/devices/platform/smapi/BAT0/cycle_count
# cat /sys/devices/platform/smapi/BAT0/current_now # instantaneous current
# cat /sys/devices/platform/smapi/BAT0/current_avg # last minute average
# cat /sys/devices/platform/smapi/BAT0/power_now # instantaneous power
# cat /sys/devices/platform/smapi/BAT0/power_avg # last minute average
# cat /sys/devices/platform/smapi/BAT0/last_full_capacity
# cat /sys/devices/platform/smapi/BAT0/remaining_percent
# cat /sys/devices/platform/smapi/BAT0/remaining_running_time
# cat /sys/devices/platform/smapi/BAT0/remaining_charging_time
# cat /sys/devices/platform/smapi/BAT0/remaining_capacity
# cat /sys/devices/platform/smapi/BAT0/design_capacity
# cat /sys/devices/platform/smapi/BAT0/voltage
# cat /sys/devices/platform/smapi/BAT0/design_voltage
# cat /sys/devices/platform/smapi/BAT0/manufacturer
# cat /sys/devices/platform/smapi/BAT0/model
# cat /sys/devices/platform/smapi/BAT0/barcoding
# cat /sys/devices/platform/smapi/BAT0/chemistry
# cat /sys/devices/platform/smapi/BAT0/serial
# cat /sys/devices/platform/smapi/BAT0/manufacture_date
# cat /sys/devices/platform/smapi/BAT0/first_use_date
# cat /sys/devices/platform/smapi/BAT0/temperature # in milli-Celsius
# cat /sys/devices/platform/smapi/ac_connected
</pre>

The raw status data is also available, including some fields not listed above (in case you can figure them out):

:{{cmdroot|cat /sys/devices/platform/smapi/BAT0/dump}}

In all of the above, replace <tt>BAT0</tt> with <tt>BAT1</tt> to address the 2nd battery.

Note that the battery status readout conflicts with the stock [[HDAPS|hdaps]] driver, so if you use <tt>hdaps</tt> you will need to load <tt>tp_smapi</tt> using {{cmdroot|1=make load HDAPS=1}} (see [[#Bundled hdaps driver|Bundled hdaps driver]] below).

On [[ACPI]]-enabled systems, most of above information is also available through the files under {{path|/proc/acpi/battery}}. However, the ACPI interface does not include the instantaneous power and cycle count readouts, and does not work well when [[How to use UltraBay batteries|hotswapping UltraBay batteries]].

====Scripts====
Some scripts can make it easier to grep the information you need from tp_smapi
* [[battery.rb]]

===Other features===

There is also [[sysfs]] attribute for making direct SMAPI requests to the SM BIOS firmware. Don't touch it unless you really know what you're doing. Example:
# echo '211a 100 0 0' > /sys/devices/platform/smapi/smapi_request; cat /sys/devices/platform/smapi/smapi_request
211a 34b b2 0 0 0 'OK'
The "4b" in the 2nd value, converted to decimal, is 75: the current charging stop threshold (stop_charge_thresh).

===Bundled <tt>hdaps</tt> driver===

The tp_smapi package includes a modified version of the <tt>hdaps</tt> Linux kernel driver used by the [[HDAPS]] system. It has remained outside the mainline kernel for a few years for several reasons, [https://lists.ubuntu.com/archives/kernel-team/2009-April/005565.html] including the upstream maintainer's assertion that the new code's anonymous author was under a NDA. (Although this would not normally expose the kernel team to litigation.) [http://lkml.org/lkml/2008/9/15/126] [http://lkml.org/lkml/2008/10/7/403] [http://lkml.org/lkml/2008/10/7/428]

To use <tt>tp_smapi</tt> and <tt>hdaps</tt> concurrently, you '''must''' use the modified version.

To build the modified version, simply append the <tt>HDAPS=1</tt> parameter to the <tt>make</tt> command (see [[#Installation|Installation]] above):
:{{cmdroot|1=make load HDAPS=1}}
or
:{{cmdroot|1=make install HDAPS=1}}

If you don't do that, you will not be able to load <tt>tp_smapi</tt> (and its support module <tt>thinkpad_ec</tt>) when <tt>hdaps</tt> is loaded, and vice versa. You can use <tt>rmmod</tt> to switch between these modules.

Note that some of the battery status is also visible through ACPI ({{path|/proc/acpi/battery/*}}), independently of <tt>tp_smapi</tt>.

The modified <tt>hdaps</tt> has several changes:
* The <tt>hdaps</tt> driver in mainline kernels conflicts with the extended battery status (they use the same IO ports). The modified <tt>hdaps</tt> coordinates this access through the bundled <tt>thinkpad_ec</tt> driver.
* The modified <tt>hdaps</tt> driver fixes reliability and improves support for recent ThinkPad models (*60 and newer), since unlike the mainline driver, it correctly follows the Embedded Controller communication protocol.
* Several other improvements, such as the ability to control the polling rate.

===Troubleshooting===
==== <tt>thinkpad_ec: cannot claim io ports 0x1600-0x161f</tt> ====
The "<tt>thinkpad_ec: cannot claim io ports 0x1600-0x161f!</tt>" error message is printed when loading the <tt>thinkpad_ec</tt> module on some recent ThinkPad models. This occurs because the ACPI BIOS DSDT is reserving ports used by tp_smapi.

As a workaround, add the <tt>force_io=1</tt> module parameter to <tt>thinkpad_ec</tt> in {{path|/etc/modprobe.conf}} (or your distribution's equivalent). Add the line:
: options thinkpad_ec force_io=1

For transient testing, load the modules as follows:

: {{cmdroot|1=make load HDAPS=1 FORCE_IO=1}}

Note: force_io option was added in tp_smapi v0.40 (released 2008-12-16).

Models which need this option include:
* ThinkPad {{T400}}
* ThinkPad {{T500}}
* ThinkPad {{X301}}

More information:
* http://bugzilla.kernel.org/show_bug.cgi?id=12221
* http://www.nabble.com/thinkpad_ec-fails-to-load-on-Thinkpad-T500-td19932985.html

==== <tt>thinkpad_ec: no ThinkPad embedded controller!</tt> ====
If you get "<tt>thinkpad_ec: no ThinkPad embedded controller!</tt>" when trying to load the module on a supported model listed below, you should [[BIOS_Upgrade|upgrade your BIOS]]. Some early BIOS (like 1.x on the X31) don't handle the embedded controller.

==== <tt>T60p writing to start_charge_thresh/stop_charge_thresh does not work!</tt> ====
Writing to /sys/devices/platform/smapi/BAT0/start_charge_thresh succeeds, but the older value does not change. Solution: unknown. If you know a solution please update here.

UPDATE: Failure to effectively change sysfs values sometimes happens at boot time (through sysfs.conf OR etc/local.start for instance) when the values have never previously been changed manually (ie using echo from a shell). Try initializing the values manually before including them in boot-time scripting.

=====SL series and IdeaPad=====
|-
! colspan=12 style="text-align:left" |
The ThinkPad SL series and IdeaPad series have firmware that is completely different from other ThinkPad models. Neither [[tp_smapi]] nor [[thinkpad-acpi]] support these models.
|}
</div>

SMAPI capabilities may depend on the BIOS version as well, so upgrading to the latest version of the BIOS might provide more SMAPI functions (especially true for long-lived BIOS with lots of releases, like the TP-1R).

Please update the above and report your experience on the [[Talk:tp_smapi|discussion]] page. If the module loads but gives a "<tt>not supported</tt>" or "<tt>not implementeded</tt>" error when you try to use some specific file in {{path|/sys/devices/platform/smapi/}}, please report the <tt>dmesg</tt> output and whether the corresponding functionality is available under Windows - maybe your ThinkPad just can't do that.

While at it, you may also want to add your laptop to the [[list of DMI IDs]].

=====HDAPS axis orientation=====
1 The HDAPS axis orientation is set using the <tt>invert</tt> module parameter (at load time) or sysfs attribute (at runtime). The <tt>hdaps</tt> driver of tp_smapi supports all 8 possible sensor orientations (inversion and swapping). You can use [[HDAPS#Visualisation_of_ThinkPad_orientation|hdaps visualisation]] to check if the settings is correct.

The <tt>invert</tt> parameter is an integer between 0 and 7, whose meaning is defined below. (This is confusing. Most people will find it easier to just try all 8 possibilities.)

Let <tt>X</tt> and <tt>Y</tt> denote the hardware readouts. Let <tt>R</tt> denote the laptop's roll (tilt left/right), and let <tt>P</tt> denote the laptop's pitch (tilt forward/backward). The possible values are as follows:
invert=0: R= X P= Y (same as mainline)
invert=1: R=-X P=-Y (same as mainline)
invert=2: R=-X P= Y (new)
invert=3: R= X P=-Y (new)
invert=4: R= Y P= X (new)
invert=5: R=-Y P=-X (new)
invert=6: R=-Y P= X (new)
invert=7: R= Y P=-X (new)

[[Category:Drivers]] [[Category:Patches]]

===Tools using this driver===

The driver's interface can be accessed directly through the files under {{path|/sys/devices/platform/smapi}}, or via the following tools:
* [[KThinkBat]] - display battery status on the KDE <tt>kicker</tt> panel.
* [[gkrellm-ThinkBat]] - battery status plugin for Gkrellm2
* {{CodeRef|thinkpad-smapi.sh}} - script to display various SMAPI information using tp_smapi module.

Idle consumptions

2007-11-25T23:51:44Z

Ychao: add X41

This page reports the minimal consumptions of Thinkpads when idle. This means, in principle: minimum brightness, CPU and GPU at lowest speed, no wifi, hard drive spun down, no pcmcia cards inserted (see details of each entry).

This kind of information has several uses: comparing one's consumption with that of other people's setups, knowing which model to use as a gateway/file server, etc.

Ychao: /* Compatibility with large memory? */

==Suspend2 + SATA resume on 2.6.14?==

Anyone got suspend-to-RAM (with the 3rd patch from [[Problems with SATA and Linux]]) and Suspend2 working with kernel 2.6.14? It's "either, or" for me, when using both patches I get rather nasty looking kernel oops when hibernating...

--[[User:Spiney|spiney]] 08:03, 10 Nov 2005 (CET)
----

Yes, it works fine for me on a T43. Are you using the latest Suspend2? Did you try hibernating from single mode, or even from <tt>init=/bin/sh</tt> mode, to make sure it's not a driver issue?

--[[User:Thinker|Thinker]] 11:59, 10 Nov 2005 (CET)
----

Yes, latest 2.2-rc9 for 2.6.14. Basically it works, the notebook just doesn't power off at the end of suspending, but when running with all the debugging options turned on I got an oops in xfsbufd, so maybe it has something to do with me using xfs. What filesystem types are you using?

Haven't retried after that, bit scared about losing data, don't have time to reinstall everything atm. Once I got a bit more spare time I'll give it another go. suspend 2.1.9.5 for 2.6.12 worked fine, so I suppose it's not driver issue.

--[[User:Spiney|spiney]] 12:53, 10 Nov 2005 (CET)
----

Oh, and I get that power off issue too, but it otherwise works and I didn't try enabling debug. I'm using ext3 in this machine (it got the most testing, so probably a good choice given all the oddball software and hardware in laptops). Are you using the file writer to hibernate to a file on xfs? There was a recent post by the developer about this being broken.

--[[User:Thinker|Thinker]] 13:01, 10 Nov 2005 (CET)
----

Once I have time and scheduled IBM to replace my harddisk (the whining sounds it makes is really getting on my nerves, why get a 5400rpm drive if it's that loud?) I'll probably setup the system with ext3 and reinstall from the latest backup. Not using the filewriter btw.

Regarding the power off issue, changing the PoweroffMethod to 3 helps. Oh, and does your machine beep at suspend and resume (once each time) and didn't with older suspend2 versions? Mine did. Oh well, doesn't matter atm.

--[[User:Spiney|spiney]] 17:43, 10 Nov 2005 (CET)
----

Are you sure "PowerdownMethod 3" really shuts down your machine? Here it does suspend to RAM, like it should, giving a Redisafe-like behavior (which is quite useful by itself, but consumers non-zero power.)

--[[User:Thinker|Thinker]] 19:01, 10 Nov 2005 (CET)
----

it doesn't shutdown the machine as in power off, but I meant it's a workaround in case you actually want to hibernate, remove the power cord (I almost never have the battery inserted, sockets almost everywhere I am) and walk away without having to press the power button to manually power off the machine.

but of course, that's not really equivalent to powering off and does consume power.

--[[User:Spiney|spiney]] 20:37, 10 Nov 2005 (CET)
----

If you unplug the power cord and don't have a bettery, it will power off by itself quite nicely. :-)

BTW, I likewise often work without a battery, both to avoid battery wear at full charge (we must find a way to control the charge threshold!) and to reduce weight. I wish there was some kind of light, low-capacity battery available, both to plug the gaping hole in the back and for the all-too-frequent accidents when I clumsily unplug the power cord. I wonder if this can be achieved surgically. The 6-cell battery have 3 cells in serial times 2 in parallel, so maybe one can take a used 6-cell battery and yank out 3 cells (and for best effect also replace the 3 remaining ones with 3 small low-capacity Li-Ion cells). Heck, even an empty 6-cell shell would be better than nothing.

--[[User:Thinker|Thinker]] 21:32, 10 Nov 2005 (CET)
----

Damn, you got me there, indeed just ripping out the cord works fine. ;)

And a small battery (having the 9-cell myself) with controlled charging would be nice, I second that, at least as mini-UPS for the (luckily not many in my area) times when there's a power outage.

== libata and suspend2 ==

I can't get suspend for a long time. After getting libata working (Gentoo no-sources 2.6.18) it works perfect and fast. It do not need, in my case, extra_page_allowance.

I'm not sure is it only on my notebook and I'd like to informe about it without changing main page.

Recently after upgrading the memory of my X41 to have 1.5 GB in total, software suspend 2 (2.6.16-2111, 2.6.17-2187 fc5 cubbi) always freezed when atomic restoring finished. This problem seems to be gone with 2.6.18-1.2257.fc5 cubbi. But I need to set full_pageset2 to 1 to avoid some random problem during suspending. I'm curious if this is a common problem or not?

Ychao: Compatibility with large memory?

==Suspend2 + SATA resume on 2.6.14?==

Anyone got suspend-to-RAM (with the 3rd patch from [[Problems with SATA and Linux]]) and Suspend2 working with kernel 2.6.14? It's "either, or" for me, when using both patches I get rather nasty looking kernel oops when hibernating...

--[[User:Spiney|spiney]] 08:03, 10 Nov 2005 (CET)
----

Yes, it works fine for me on a T43. Are you using the latest Suspend2? Did you try hibernating from single mode, or even from <tt>init=/bin/sh</tt> mode, to make sure it's not a driver issue?

--[[User:Thinker|Thinker]] 11:59, 10 Nov 2005 (CET)
----

Yes, latest 2.2-rc9 for 2.6.14. Basically it works, the notebook just doesn't power off at the end of suspending, but when running with all the debugging options turned on I got an oops in xfsbufd, so maybe it has something to do with me using xfs. What filesystem types are you using?

Haven't retried after that, bit scared about losing data, don't have time to reinstall everything atm. Once I got a bit more spare time I'll give it another go. suspend 2.1.9.5 for 2.6.12 worked fine, so I suppose it's not driver issue.

--[[User:Spiney|spiney]] 12:53, 10 Nov 2005 (CET)
----

Oh, and I get that power off issue too, but it otherwise works and I didn't try enabling debug. I'm using ext3 in this machine (it got the most testing, so probably a good choice given all the oddball software and hardware in laptops). Are you using the file writer to hibernate to a file on xfs? There was a recent post by the developer about this being broken.

--[[User:Thinker|Thinker]] 13:01, 10 Nov 2005 (CET)
----

Once I have time and scheduled IBM to replace my harddisk (the whining sounds it makes is really getting on my nerves, why get a 5400rpm drive if it's that loud?) I'll probably setup the system with ext3 and reinstall from the latest backup. Not using the filewriter btw.

Regarding the power off issue, changing the PoweroffMethod to 3 helps. Oh, and does your machine beep at suspend and resume (once each time) and didn't with older suspend2 versions? Mine did. Oh well, doesn't matter atm.

--[[User:Spiney|spiney]] 17:43, 10 Nov 2005 (CET)
----

Are you sure "PowerdownMethod 3" really shuts down your machine? Here it does suspend to RAM, like it should, giving a Redisafe-like behavior (which is quite useful by itself, but consumers non-zero power.)

--[[User:Thinker|Thinker]] 19:01, 10 Nov 2005 (CET)
----

it doesn't shutdown the machine as in power off, but I meant it's a workaround in case you actually want to hibernate, remove the power cord (I almost never have the battery inserted, sockets almost everywhere I am) and walk away without having to press the power button to manually power off the machine.

but of course, that's not really equivalent to powering off and does consume power.

--[[User:Spiney|spiney]] 20:37, 10 Nov 2005 (CET)
----

If you unplug the power cord and don't have a bettery, it will power off by itself quite nicely. :-)

BTW, I likewise often work without a battery, both to avoid battery wear at full charge (we must find a way to control the charge threshold!) and to reduce weight. I wish there was some kind of light, low-capacity battery available, both to plug the gaping hole in the back and for the all-too-frequent accidents when I clumsily unplug the power cord. I wonder if this can be achieved surgically. The 6-cell battery have 3 cells in serial times 2 in parallel, so maybe one can take a used 6-cell battery and yank out 3 cells (and for best effect also replace the 3 remaining ones with 3 small low-capacity Li-Ion cells). Heck, even an empty 6-cell shell would be better than nothing.

--[[User:Thinker|Thinker]] 21:32, 10 Nov 2005 (CET)
----

Damn, you got me there, indeed just ripping out the cord works fine. ;)

And a small battery (having the 9-cell myself) with controlled charging would be nice, I second that, at least as mini-UPS for the (luckily not many in my area) times when there's a power outage.

== libata and suspend2 ==

I can't get suspend for a long time. After getting libata working (Gentoo no-sources 2.6.18) it works perfect and fast. It do not need, in my case, extra_page_allowance.

I'm not sure is it only on my notebook and I'd like to informe about it without changing main page.

Pentium M undervolting and underclocking

2006-11-12T02:44:05Z

Ychao: /* Tested frequencies */

== Background ==

Intel Pentium M processors from the [[Intel Pentium M (Dothan)|Dothan]] and [[Intel Pentium M (Banias)|Banias]] families can be instructed to operate at voltage and clock frequencies lower than the nominal ones recommended by Intel and used by ThinkPads by default. Experience shows that the processor may continue working correctly at lower-than-nominal voltages and frequencies, thereby reducing power consumption, heat and fan noise.

In the Pentium M, speed and voltage are controlled by software (through the MSR registers). It is up to the operating system to choose the right voltage for each frequency. Normally this is done according to tables published by Intel or according to ACPI tables. However, this can be overriden - in the case of Linux, by a kernel patch.

{{WARN|Following this instructions will operate your CPU under conditions it was not designed for. Even if your system seems stable, it may still suffer transient faults leading to arbitrary data corruption. In addition, errors in following these instructions (or changes between processor models) may operate the CPU ''above'' its nominal parameters, which, if taken too far, can cause kernel panics or even possibly hardware damage}}

For an example of what may be achieved, consider these examples: when voltages on one ThinkPad {{T43}} were reduced by 20-30%, stable CPU temperature dropped by 7-10deg under both idle and burn-in conditions. Combined with [[how to control fan speed|fan speed control]], this greatly reduced the [[Problem with fan noise|problem with fan noise]]. On one user's ThinkPad {{R51}}, an undervolt brought the full-load processor temperature down from 87 degrees to 63 degrees while maintaining full stability. The effect was, however, negligible at idle.

{{NOTE|While under''volting'' has a clear measurable effect, it's not clear if under''clocking'' really works. <tt>/proc/cpuinfo</tt> reflects the underclocked frequency, but enabling debug output on <tt>cpufreq</tt> causes it to say things like "<tt>CPU frequency out of sync: cpufreq and timing core thinks of 533000, is 800000 kHz.</tt>" where the former is the chosen underclocked frequency and the latter is the documented minimum frequency. This discrepancy also causes [[Software Suspend 2]] to oops during suspend.}}

There are several methods to control CPU voltage in Linux, and currently all of them require a patched kernel.

== Alternative 1: patch with hard-coded voltages ==
=== Instructions ===

# Determine the stable voltages for each frequency, using some overclocking/undervolting utility that has specific support for Pentium M ("Centrino") processors. It seems that no such utility exists for Linux. For windows, one good choice is [http://www.pbus-167.com/chc.htm Notebook Hardware Control (NHC)], which conveniently also includes a table of nominal frequencies and voltages (in its help file). Ascertain that at the undervolted settings the CPU actually performs correct computation ([http://www.mersenne.org/freesoft.htm Prime95] in "Tortute Test" mode seems to be a good partial test emphasizing FPU and memory access). Note that beside reducing voltages (undervolting), you can also try to add lower frequencies (underclocking). If you undervolt a particular frequency too much your machine is likely to crash, so try not to have any other programs open.
# Determine the model name string reported by the CPU, e.g., via the "<tt>Model name</tt>" line in {{path|/proc/cpuinfo}}, and likewise the <tt>cpu_family</tt>, <tt>model</tt> and <tt>stepping</tt>.
# Grab a copy of the example patch below and update it to reflect the parameters, frequencies and voltages you found.
# Apply the patch to your kernel (tested with 2.6.13.1 and 2.6.14-rc2).
# To prevent the ACPI table from overriding your table, disable the <tt>CONFIG_X86_SPEEDSTEP_CENTRINO_ACPI</tt> kernel option.
# Compile and install the new kernel.

The changes should be active now. If you want to see debug information attesting to thus, do the following:

# Reboot in <tt>single</tt> mode.
# {{cmdroot|echo 2 > /sys/module/cpufreq/parameters/debug}}
# {{cmdroot|modprobe speedstep-centrino}}
# {{cmdroot|dmesg}} and check for the message "<tt>speedstep-centrino: found "Intel(R) Pentium(R) M processor </tt>..."

If you don't see that message, you got the <tt>cpu_id</tt> or <tt>model_name</tt> parmaeters wrong. If your system crashes, re-test the voltages and adjust accordingly.

Please report your results (including voltages)!

=== Linux kernel patch (example) ===

The following example shows how to undervolt a Pentium M 750 (1.86GHz) on a ThinkPad {{T43}}. As discussed above, the parameters are specific to this one CPU. You will need to experimentally find the correct settings for your own CPU and adjust the patch accordingly.

Note that the Pentium M 750 has a 533MHz FSB (quad-pumped 133MHz), hence the use of <tt>OP133</tt>. If you have a Pentium M with 400MHz FSB (i.e., quad-pumped 100MHz, found in [[Intel Pentium M (Banias)|Banias]] and older [[Intel Pentium M (Dothan)|Dothan]]) then in the voltage table change <tt>OP133</tt> to <tt>OP</tt>.

{{CodeRef|undervolt-pentium-m-2.6.13.1.patch}}

Don't forget to disable <tt>CONFIG_X86_SPEEDSTEP_CENTRINO_ACPI</tt>.

==Alternative 2: patch with user-space control==

{{NOTE|There's a new project under http://linux-phc.sourceforge.net/ with updated patches. Note that the list of voltages may be reversed (lowest frequency first) compared to the original patch disucssed here. }}

If you want to use the Ubuntu 2.6.15 Kernel, please have a look at this thread: http://ubuntuforums.org/showthread.php?t=146366

The [http://fabrice.bellamy.club.fr/bdz.undervolt.2005.10.22.a.patch bdz.undervolt.2005.10.22.a.patch] patch, written by Gentoo-Wiki user "Bdz", allows voltages to be changed without reboot.

It presents a userspace interface, as in the following example:
:{{cmdroot|cat /sys/devices/system/cpu/cpu0/cpufreq/voltage_table}}
:{{cmdresult|1356,1356,1356,1356,1356,1356,1356,1244,1116,988}}
:{{cmdroot|echo "1084,1084,1084,1084,1084,1084,1084,988,908,860" >/sys/devices/system/cpu/cpu0/cpufreq/voltage_table}}

The relevant [http://gentoo-wiki.com/HOWTO_Undervolt_a_Pentium_M_CPU page] on Gentoo-Wiki providues further information and some helpful hints and scripts for voltage adjustment.

When applying this patch be sure to keep the "ACPI tables for decoding frequency pairs" option -- this patch only allows adjustment of the voltages for the normal clock speeds as reported by the ACPI table in the BIOS. On some models (e.g., ThinkPad {{T43}}) this does not include all clock speeds supported by the processor.

===Initscript===
This is a Gentoo initscript for the patch from Gentoo-Wiki user "Bdz".

==Alternative 3: another patch with user-space control==

The [http://avkrok.net/nw8240/centrino-voltages.diff centrino-voltages.diff] patch, written by Rickard Holmberg, also provides user-space control. See [http://avkrok.net/nw8240/ here] and [http://mailman.linux-thinkpad.org/pipermail/linux-thinkpad/2005-December/030772.html here] for usage.

==Stress Testing==

This [[Undervolt Stress Testing Script|script]] illustrates a very conservative method to stress test your lowered voltage settings.

==Tested frequencies==

If you have done excessive testing with user defined frequencies (stable system for over a month).
and no lookups occur when computing primes with mprime http://mersenne.org/ (gentoo: 'emerge gimps')
you can post your frequencies here. But note that this is just a rough indication, since the stable values will differ between individual processors, even in the same model.

Problem with APS harddisk parking

2006-11-12T02:27:19Z

Ychao: /* Supported/unsupported harddrive firmwares */

{| width="100%"
|style="vertical-align:top;padding-right:20px;width:10px;white-space:nowrap;" | __TOC__
|style="vertical-align:top" |
When trying to [[How to protect the harddisk through APS|enable APS functionality]] by installing <tt>hdaps_protect</tt> and <tt>hdapsd</tt>, the following problems might occur.
|}

==Problem with unload capabilities check==
You may get the following kernel message when the disk is protected (e.g., via {{cmdroot|echo 1 > /sys/block/sda/queue/protect}}):

ata_scsi_issue_protect_fn(): unload support NOT reported..
scsi_protect_queue(): head park not requested, used standby!..

or

idedisk_issue_protect_fn(): unload support NOT reported..
ide_protect_queue(): head park not requested, used standby!..

{{WARN|Using HDAPS in the above state may cause frequent drive spin downs, thereby wearing out your hard disk.}}

If you see this, and you are sure that your drive actually does support unloading (all original drives sold with HDAPS-equipped ThinkPads do), one of the following solutions might help.

=== Drives which have this problem ===
* [[Hitachi Travelstar 7K60]] HTS726060M9AT00 on ThinkPad {{T43}}
* Fujitsu MHT2040AH (846C) on ThinkPad {{T41}} or {{R51}}

=== Solution for kernel 2.6.16 or later ===
The <tt>hdaps_protect</tt> patch for 2.6.16 now accepts the {{bootparm|protect_method|}} module parameter to override the
parking capability detection, which accepts the following numeric values:
*<tt>0</tt>: autodetect capability
*<tt>1</tt>: "unload the head even if the drive doesn't report it has this capability"
*<tt>2</tt>: "standby even if unload is supported"

Hence, depending on your machine type, and whether the module is built into the kernel or not, you can use one of the following options:

If disk driver is built into kernel, add the following to your kernel boot parameters (e.g. {{path|/boot/grub/menu.lst}}):
libata.protect_method=1
ide-disk.protect_method=1

If disk driver is built as module, add the following to your modprobe configuration (e.g., {{path|/etc/modprobe.conf}}):
options libata protect_method=1
options ide-disk protect_method=1

In both cases, if you know whether you use <tt>ide-disk</tt> or <tt>libata</tt>, you can drop the other line.

=== Solution for kernel 2.6.15 and older ===
The following patch overrides automatic protect capability detection.

==Problem with hard drive firmware==
Drivers other than those sold by IBM for APS-equipped ThinkPads may lack the head unload command.

===Detection===
If you see the following message in {{cmdroot|dmesg}} output after you have started the hdaps daemon, your drive lacks the unload feature (the converse is not true).

ide_protect_queue(): head NOT parked!..
ide_unprotect_queue(): No pending I/O, re-enabling power management..

You can also directly test for the head unload function by running the following Perl script:

<pre>
#!/usr/bin/perl
# Unload disk head on drives that support IDLE IMMEDIATE with the UNLOAD feature.
$dev="$ARGV[0]" or die "Specify device as argument.\n";
$HDIO_DRIVE_TASK=0x031e;
$args=pack("ccccccc",0xe1,0x44,0,0x4C,0x4E,0x55,0);
open(DEV,"<",$dev) or die "open(\"$dev\"): $!\n";
ioctl(DEV,$HDIO_DRIVE_TASK,$args) or die "Unload failed: $!\n";
</pre>

Due to a limitation of the Linux kernel libata system, it is not possible for this program to check if the unload worked. You'll have to listen for the characteristic sound (a faint click and a change in spinning sound) to learn if the unload worked.

===Solutions===
A firmware upgrade of your harddisk might add the missing function.

Go to the [http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-62282 IBM harddrive firmware update utility page] and check if a firmware upgrade is available for your harddisk. IBM/Lenovo provides a bootdisk for easy firmware upgrade (~17MB download).

===Supported/unsupported harddrive firmwares===
Use {{cmdroot| hdparm -i /dev/hda}} to get your harddisk model name and firmware version (replace <tt>/dev/hda</tt> with the actual device for your hard drive).
On newer models, you need {{cmdroot| sdparm -i /dev/sda}} (or {{cmdroot| hdparm -I /dev/sda}} ) because of the SATA controller.

The following line is the important one in the output:

Model=HTS726060M9AT00, FwRev=MH4O'''A6GA''', SerialNo=MRHXXXXXXXXX

The last four characters of the '''FwRev''' actually marks the firmware version.

==Problem with Hard Drive Firmware==
In case you see a message like below in {{cmdroot|dmesg}} output after you have started the hdaps daemon,
a firmware upgrade of your harddisk might solve your problem.

ide_protect_queue(): head NOT parked!..
ide_unprotect_queue(): No pending I/O, re-enabling power management..

Go to the [http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-62282 IBM harddrive firmware update utility page] and check if a firmware upgrade is available for your harddisk. IBM/Lenovo provides a bootdisk for easy firmware upgrade (~17MB download).

===supported/unsupported harddrive firmwares===
Use {{cmdroot| hdparm -i /dev/hda}} to get your harddisk model name and firmware version (replace <tt>/dev/hda</tt> with the actual device for your hard drive).
On newer models, you need {{cmdroot| sdparm -i /dev/sda}} (or {{cmdroot| hdparm -I /dev/sda}} ) because of the SATA controller.

The following line is the important one in the output:

Model=HTS726060M9AT00, FwRev=MH4O'''A6GA''', SerialNo=MRHXXXXXXXXX

The last four characters of the '''FwRev''' actually marks the firmware version.

The table lists known working / not working firmware versions with [[HDAPS]]

#Choosing USB Boot and booting with a USB flash drive plugged in makes boot procedure extremely long (1m30 just to pass the IBM splash screen). However, it ends up booting the OS in the USB drive (assuming one is indeed present).
#Internal CD/FD means the ones in the UltraBase for X series and 570 models.
#Requires an external Floppy drive attached to Port Replicator or Dock
#Requires that the user select the drive from the disk option shown after clicking F12 on the boot sequence.
#Boots from a flash memory drive, i.e. CompactFlash (with PCMCIA adapter).
#It is working with lilo boot loader, however it failed with syslinux.

#Choosing USB Boot and booting with a USB flash drive plugged in makes boot procedure extremely long (1m30 just to pass the IBM splash screen). However, it ends up booting the OS in the USB drive (assuming one is indeed present).
#Internal CD/FD means the ones in the UltraBase for X series and 570 models.
#Requires an external Floppy drive attached to Port Replicator or Dock
#Requires that the user select the drive from the disk option shown after clicking F12 on the boot sequence.
#Boots from a flash memory drive, i.e. CompactFlash (with PCMCIA adapter).
#It is working with lilo boot loader, however it failed with syslinux.

#Choosing USB Boot and booting with a USB flash drive plugged in makes boot procedure extremely long (1m30 just to pass the IBM splash screen). However, it ends up booting the OS in the USB drive (assuming one is indeed present).
#Internal CD/FD means the ones in the UltraBase for X series and 570 models.
#Requires an external Floppy drive attached to Port Replicator or Dock
#Requires that the user select the drive from the disk option shown after clicking F12 on the boot sequence.
#Boots from a flash memory drive, i.e. CompactFlash (with PCMCIA adapter).
#It is working with lilo boot loader, however it failed with syslinux.

#Choosing USB Boot and booting with a USB flash drive plugged in makes boot procedure extremely long (1m30 just to pass the IBM splash screen). However, it ends up booting the OS in the USB drive (assuming one is indeed present).
#Internal CD/FD means the ones in the UltraBase for X series and 570 models.
#Requires an external Floppy drive attached to Port Replicator or Dock
#Requires that the user select the drive from the disk option shown after clicking F12 on the boot sequence.
#Boots from a flash memory drive, i.e. CompactFlash (with PCMCIA adapter).
#It is working with lilo boot loader, however it failed with syslinux.

|style="vertical-align:top" |This page is meant as a collection of information on how to save memory to make Linux work reasonable on older system with limited amount of RAM.

Most distributions nowadays don't take much care about it anymore, so there are a lot of things you can do to save memory. To get a smoothly working linux environment on a low memory machine you will need to conciously choose a lot of aspects of your system, most importantly the graphical environment, desktop environment and applications. This page provides detailed information about these various optimization possibilities.

==Streamlining the desktop environment==
The common Desktop environments GNOME and KDE are, in their modern state, focused more on features, integration, and beauty rather than on resource saving. Understandable, but running Linux on an older ThinkPad with limited RAM requires conscious and sensitive resource usage more than anything else. The good thing about Linux is that a lot of things stay adjustable and customizable. So lets see what we can do about desktops.

One of the most important things is to decide for one graphical widget library and stick with that when you are choosing your desktop environment and applications. Having several toolkits in use means more libraries being loaded and hence more memory being used by those. Possibilities are:
* [http://www.fltk.org/ FLTK]
* [http://www.fox-toolkit.org/ FOX toolkit]
* [http://www.gnustep.org GNUstep toolkit]
* [http://www.gtk.org/ GTK] <tt>(not recommended, use GTK 2 if possible)</tt>
* [http://www.gtk.org/ GTK 2]
* [http://www.lesstif.org/ Lesstif] / [http://www.openmotif.org/ OpenMotif]
* [http://www.trolltech.com/products/qt/index.html QT]
* [http://www.windowmaker.org/development-wings.html WINGs] <tt>(kind of a lightweight GNUstep toolkit, provided by the WindowMaker developers)</tt>
* [http://www.x.org/ X Toolkit]

Of those, at current state, there are enough applications for the X Toolkit, GTK, GTK 2 and QT to provide you with a solution for every task you should want.

===GNOME===
It's like with humans, the worst feature is in most cases also the best one. For GNOME it is probably the many little parts it consists of. Makes it hard to install, but enables one to customize the installation. So, the first thing you should do to streamline GNOME is not to launch it. Sound stupid? Well, lets have a look.

GNOME is basically a set of libraries built around the GTK+ libs and extending its functionality. Add some nice little applications, a session manager, a panel, beautiful icons, and some other stuff and you have GNOME as you know it. Reversing those additions is what you can do to use GNOME applications on a machine that this desktop environment would normally take your nerves on.

The GNOME panel, the session manager, the desktop manager and the window manager are all parts of GNOME that eat a lot of memory for something that others can do in a maybe little less beautiful but much more resource saving way.
So first off configure your login manager not to launch gnome-session at login. If you are using GDM this is quite straight forward, you just need to add a different session script, launching your favorite window manager. See the list below and pick one, lets say i.e. WindowMaker. WindowMaker uses a desktop menu, a dock and a notification area to provide you with an organized way of launching applications and iconfying running ones. So we don't need a panel anymore. Also, think if you really need icons on your desktop. If you do, think about using something like ROX filer instead of nautilus for that. In any case, tell nautilus not to manage the desktop by default by unchecking the according setting within gconf-editor. To keep GNOME applications happy we would need to have gconf and gnome-settings-manager running at every session start. One way to do this is to either include them in your new session script. They both need to be running to make GNOME applications realize their settings properly.

===KDE===
{{Todo|...}}

===Alternative Desktop Environments===
First of all, it is important to notice that GNOME and KDE are not the only Desktop Environments around.
Other complete (featuring most of: window management, session management, desktop management, file management and panel) desktop environments are:
*[http://xfce.org/ XFCE] <tt>uses GTK 2</tt>
*[http://ede.sourceforge.net Equinox Desktop Environment] <tt>uses eFLTK, a modified version of FLTK</tt>
*[http://www.nongnu.org/antiright/ AntiRight Desktop Environment] <tt>uses LessTif / OpenMotif</tt>
*[http://foxdesktop.sourceforge.net/ FOX Desktop Environment] <tt>uses FOX Toolkit</tt>
*[http://www.gnustep.org/ GNUstep] <tt>provides it's own toolkit</tt>

But also, some Window Managers exceed the task of managing windows towards providing a functional workbench. See below for a list.

===Building your own Desktop===

====Window Manager====
If you want to build your own customized desktop, a good start is choosing the window manager of your liking.

Here's a list of some of them:
*including basic Desktop Environment functionality
**the [[Wikipedia:NextStep|NextStep]] alike ones
***[http://www.windowmaker.org/ WindowMaker] <tt>(probably the most widespread NextStep like WM)</tt>
***[http://www.afterstep.org/ AfterStep] <tt>(another one of those)</tt>
***[http://blackboxwm.sourceforge.net/ BlackBox]
***[http://fluxbox.sourceforge.net/ FluxBox] <tt>(tabbed windows, lighweight)</tt>
**others
***[http://www.icewm.org/ IceWM] <tt>(lightweight, widespread)</tt>
***[http://enlightenment.sourceforge.net/ Enlightenment] <tt>(lots of features and eye candy)</tt>
***[http://www.pekwm.org PekWM] <tt>(kind of a one man show, but feature rich and extremely customizable)</tt>
*pure WindowManagers
**[http://golem.sourceforge.net/ Golem]
**[http://home.earthlink.net/~lab1701/larswm/ LarsWM] <tt>(unique tiling Window Manager)</tt>
**[http://www.nongnu.org/ratpoison/ ratpoison] <tt>(modeled after gnu screen)</tt>
**[http://fvwm.org/ fvwm] <tt>(small but powerful)</tt>
**[http://www.all-day-breakfast.com/wm2/ wm2] <tt>really small Window Manager</tt>
**[http://www.all-day-breakfast.com/wmx/ wmx] <tt>slightly more featureful version of wm2</tt>

====Taskbar/Panel====
Another thing that especially users coming to Linux from the Windows world would probably like is a Panel or Taskbar.

Here's a collection of independant low resource panels:
*[http://www.chatjunkies.org/fspanel/ F***ing Small Panel] <tt>(doesn't use any toolkit)</tt>
*[http://freshmeat.net/projects/hpanel/ HPanel] <tt>(doesn't use any toolkit)</tt>
*[http://fbpanel.sourceforge.net/ fbpanel] <tt>(depends on GTK 2)</tt>
*[http://jodrell.net/projects/perlpanel Perl Panel] <tt>(depends on GTK 2, gnomevfs, perl)</tt>
*[http://www.gkrellm.net/ GKrellM] <tt>(depends on GTK 2, flexible plugin based skinable vertical panel)</tt>

====Desktop Pinboard====
Then, the next thing you might be looking for is how to get icons onto your desktop. Usually this is done by the file manager who displays the content of a special directory as icons on the desktop. See the File Manager section to follow this approach.

However, you might decide for a really lightwight file manager which doesn't offer this feature. In that case all hope is not lost, for there are also special programs specialized in desktop icon management. Such are:
* [http://idesk.sourceforge.net/ iDesk] <tt>(recent versions need imlib2 only)</tt>

====File Manager====
File Managers are the fourth really important compontent of a desktop environment. There are plenty out their ranging from resource hugs to really lightweight and slim ones.

File Managers come with three distinct general user interface approaches: the two pane gui, the spacial and the browser gui. The browser gui is the one the Windows Explorer starting from Windows 2000 uses as well as earlier versions of Nautilus. The spacial view is the one known from Windows 95 and more recent versions of Nautilus. The two pane view is know to many from Norten Commander, Directory Opus or your favorite FTP client.

==Choosing applications==
===Web Browser===
This is highly dependend on the way you use your browser, it's often worth it to try out all and just track general
memory usage. Remember that <tt>top</tt> and <tt>ps</tt> don't report correct memory usage, track totals only.

====Firefox====
Firefox is graphical web browser. One can install features like AdBlock and FlashClicktoplay which will decrease memory and
processor usage by hiding Flash and Java -adverts.

====Opera====
Opera is graphical web browser. You can easily enable/disable plug-ins and java (press F12) and decrease memory usage.
Opera uses QT as toolkit, so you may shave off some Mbytes off memory usage by using dynamically linked version if you use KDE.

====Konqueror====
Konqueror is graphical web browser. It's integrated with KDE and has several advanced features (esp. ca. KDE 3.5).
You may save some megabytes by using it instead of other browsers when using KDE.
It's not necessarily heavy even when used without running KDE.

====Dillo====
Dillo is minimalistic and very small graphical web browser.

====Elinks/Lynx====
elinks/lynx are both text mode web browsers. <tt>elinks</tt> handles tables and formatting much nicer than <tt>lynx</tt>.
Both go very easy on memory footprint.

{{Todo|...}}

==Disabling unneeded system deamons==
Another thing you can do to improve performance is to get rid of unneaded system daemons launched from your init scripts. Disable them by using the according configuration interface of your distro or by deleting links in the according runlevel directories (usually in <code>/etc/rc.d/</code>).

Daemons you usually don't need:
* httpd <tt>(Apache web server)</tt>
* mysqld <tt>(MySQL database server)</tt>
* smbd <tt>(SMB windows filesharing server)</tt>
* pppd <tt>(PPP server for connections through modems and serial lines)</tt>

==Adjusting filesystems==
You can also try to optimize memory usage by making sure that you have as little as possible of your filesystem residing in RAM. To do this make sure that the following mount points are set to reside on your harddisk in {{path|/etc/fstab}}.
* /dev (not possible if you use udev)
* /tmp

==Other tips==
===Disk space===
When using Debian/Ubuntu/other derivative, use <tt>aptitude</tt> as package manager, and use it as soon as possible. Use it and only it to install and remove packages.

One of it's most usefull features is that it tracks packages you install and marks packages installed via dependency as such, so when you remove a package that is no longer used, or package updates and doesn't use a library anymore, that dependency will get uninstalled.

You can mark packages installed as automatically installed by hitting 'M' (uppercase m), it will be marked for deinstallation if it's not longer required.

You could also install localepurge wich will remove all unneded locales and localized manpages for packages you install.

Talk:How to enable integrated fingerprint reader with BioAPI

2006-03-09T23:41:33Z

Ychao: /* Multifinger */

== chmod 777 -R /usr/local/var/bioapi/ ==

Is the above necessary? I just made a debian package of xscreensaver with the patch applied, and when using the bioapi debian pacakge from [http://www.qrivy.net/~michael/temp/ Michael R. Crusoe's site] which has this directory put in /usr/var/bioapi I had not to change the permissions to world-writeable there. Write access to the logfile and usb device are necessary, but that directory works with 755 as well (even though it comes with 777 in Michael's package), and all files and subdirectories are 644/755 too.

I didn't get it to work anyway, but I'm curious about your Qt version(s) as it seemed to want Qt 3 when I was playing with it.

== using absolute paths for commands ==

I don't know whether using absolute paths in the articles is a good idea, at least not for tools like {{cmd|lsusb|}} which are not established utilities (i.e. used for more than a decade or something ;)) and happen to be in different locations in different distributions. E.g. said {{cmd|lsusb|}} resides in {{path|/usr/sbin|}} on Debian systems.

--[[User:Spiney|spiney]] 16:45, 12 Nov 2005 (CET)
----

I'm using debian testing and it's in {{path|/usr/bin|}}. I agree that the confusion is bad; dropping the absolute paths and adding a general note about checking {{cmd|$PATH|}} in case of problems is probably good.

== BioAPI error #3 ==

Its kind of strage it used to work with everythig (kdm,console,lock,etc)
Now it only works with kdm. It allways gives back:

pam_bioapi[8113]: Unable to initialize Bioapi framework, BioAPI error #:3.

Even when I set the right permissions on /proc/bus/usb.

I am able to run the Sample program as normal user after setting the permissions, but when I change within a user session by su I amnot able to run the Sample program a also get an error Code #3.

From an other terminal (alt+strg+Fx) I am able to run the Sample program but at the login I still get the error #3.

I cant remember to have changed anything an d bevor I was able to login in a console with my fingerprint now only kdm is working even kde lock-session
isnt working anymore.

Any suggestions ?

==Permission errors exclusive to xscreensaver==

I followed the instructions above and got everything working, including non-root programs like xscreensaver. However, the script to change usbfs permissions is finicky and fails to work with a lot of things like suspend/resume. Therefore, I switched to specifying <tt>devgid=108,devmode=0660,busgid=108,busmode=0770,listgid=108,listmode=0660</tt> as mount parameters for usbfs, where group 108 is a group I created and added my normal user to. This seems like a much better way of doing things, and it almost works. However, xscreensaver (using the newer patch) gives the familiar <tt>Unable to load BioAPI BSP with UUID of <nowiki>{</nowiki>5550454b-2054-464d-2f45-535320425350<nowiki>}</nowiki>, BioAPI error #194d.</tt> error in {{path|/var/log/auth.log|}}. I don't think this is a straightfoward permissions problem because
<ul>
<li>the permissions in {{path|/proc/bus/usb|}} are correct by inspection</li>
<li>I can write to the device file as my normal user</li>
<li>other programs like {{cmd|test_verify-pam_bioapi|}} and [http://pamtester.sourceforge.net/ {{cmd|pamtester|}}] work as my normal user</li>
<li>the weirdest one: xscreensaver works when the {{cmd|xscreensaver|}} daemon is launched from within {{cmd|strace|}}. It's still running as my normal user ({{cmd|strace|}} is not setuid root). I have absolutely no idea what would cause this. I thought it might be an environment issue, but the difference in environment between the {{cmd|strace|}} session and my normal session is trivial.</li>
</ul>

At this point I'm hoping it's something dumb, but I'm out of ideas. The {{cmd|xscreensaver|}} error is <tt>pam_authenticate (...) ==> 7 (Authentication failure)</tt>, for the record.

--[[User:keegan|keegan]]
----

Could you provide all the log lines between pam_start and pam_end when running {{cmd|xscreensaver -verbose|}}?

BTW, the idea with using the mount options for usbfs is very good, maybe you should add that info to the article page? I use the permission changing script without problems, also after resume, but the usbfs version is probably easier to set up, most people will be able to find {{path|/etc/fstab|}}.

So we've got the first attempt with {{cmd|pam_bioapi|}}, which fails immediately (no sign of the GUI fingerprint prompt, nor a "silent" chance to swipe the finger as with xdm), then the fallback to {{cmd|pam_unix|}} which succeeds. Earlier I had xscreensaver set up to only try {{cmd|pam_bioapi|}}, with essentially the same result -- it gives up on pam entirely and does unix auth itself.

I'd really like to strace the pam module and see what it's attempting to do to {{path|/proc/bus/usb|}}, but as that actually fixes the problem I'm kinda at a loss. Maybe there's some kernel option to print debugging info for usbfs? I'd be all for changing the article to suggest using mount options in {{path|/etc/fstab|}}, if it weren't for this one weird bug. Has anyone else had the same problem?

==Driver Expiring!!!==
Don't anyone notice that both betas of the UPEK driver is expiring in
about a month in the new year, Jan 1st 2006? They really mean it!
I set my computer date to next year and get a message "the driver has expired" when using fingerprint reader! This is a grave threat to our computer lifestyle, i.e. for those of us who got it working and use it
daily:)
Is there any workaround other than setting the date back a year when
new year come and wait for new driver? Is there a way to figure out where exactly in the driver it checked the date and how? The must have set it
somewhere in file libtfmessbsp.so, but it is binary and I can't figure out how to Reverse Engineer it.

---Jiang

Yes, the beta driver will expire. The final version (which is due REALLY soon now) will not.

Sumedha

Any news? Just 9 days left to expiry. --[[User:Thinker|Thinker]] 21:36, 22 Dec 2005 (CET)

The final is out, get it at [http://www.upek.com/support/dl_linux_bsp.asp UPEK's download page]. And how does one edit the industry watch section of the main page?

--[[User:Spiney|spiney]] 21:39, 22 Dec 2005 (CET)

Ah, great! Both the article page and the driver page it points to are out of date... For the news, just follow the "[[ThinkWiki:News|News]]" link in the main page.

--[[User:Thinker|Thinker]] 21:44, 22 Dec 2005 (CET)

As this is now very soon I've updated the article page to link to the final driver, which is better in a few ways anyway. This is unless anyone minds (are there any unresolved issues with the final that don't exist in the betas?).

== Updated xscreensaver patch ==

I've tried to address some usability issues with the old patch, e.g. that it calls the PAM bioapi module twice before falling back to the normal authentication methods.

== Fingerprint or password ==

Is there any way to have PAM accept either a password or a finger swipe, right away? Sometimes one is more convenient, sometimes the other, so and it's a lot of trouble to wait for the UPEK scanner prompt and then cancel it in order to reach the password entry.

If you get the following in {{path|/var/log/secure}} when you try to unlock the KDE screensaver, it means you forgot to set the USB device permissions.

==xscreensaver 4.23+fingerprint.patch causes xscreensaver-gl to crash kernel==

I've gotten bioapi and 'Sample' to allow me to enroll my fingerprint, and I've also experienced the 'two logon' issue.

I compiled xscreensaver 4.23 (though it seemed that apt came with 4.24) and applied the patch. My goal was to have the fingerprint prompt come up and to see the "bad image" of the fingerprint scan.

The first time I did this, xscreensaver-gl took a dump and was causing kernel crashes. So I went and got the newest xscreensaver source and patches, and applied the bioapi patch to those. It worked (meaning it didnt crash the kernel anymore ;b )

It would seem that there is a /etc/pam.d/xscreensaver, so I commented everything out of that except the bioapi line.

Locking xscreensaver, then attempting to unlock didnt show me any fingerprint requirements, and my password didnt work.

I'm wondering if theres something that was left out of the xscreensaver howto? or if theres anyone out there who's gotten the xscreensaver portion of this to work, who would be willing to help me out :)

== gdm hangs on kde logout ==

Hi.

I am using a Thinkpad t43, installed with gentoo.
I run gdm as the login manager, with kde 3.4 and enlightenment dr16 as the window manager.

I followed the steps in the wiki, and the biometric scanner is now working fine, appart from the fact that when I close/end the session I just get a blank screen, in place of the gdm login screen.

Disabling the biometrics (by setting the pam.d file back to their originals), the session ends fine. I do this for a few times, and then set the biometrics back again, and it work fine for a few logouts, and then back to the blank screen again.

I can do ctrl+shift+f1 to get to a console window and from there I can issue a shutdown.
Although this works ok, it is a bit of a pain.

Any ideas ?

== 'gksudo' Doesn't show biopam finger swipe prompt... ==

Hey all,

First off... this is an excellent how-to! I have no real interest in using fingerprint scanner with xscreensaver, but it was up and working with everything else on my system pretty much effortlessly.

I'm running Ubuntu Breezy Badger 5.10 on an IBM T43p (2678) and have run into two oddities:
1) /etc/pam.d/xscreensaver - as it is initially configured, if you have an xscreensaver session set to require password (or xlock with screensaver) then you get prompted for the normal text-password entry and then will be prompted to swipe your finger... This is easily fixed by commenting out the '@include common-auth' line in /etc/pam.d/xscreensaver and adding the line 'auth required pam_unix.so nullok_secure'. After that change it only prompts for the text-password entry challenge.

2) gksudo - This is more of a pain... I can use the fingerprint scanner with gksudo, but gksudo doesn't prompt with the (ugly-but-functional) finger swipe dialog the way that gdm does during login or xscreensaver does when configured as mentioned above (pre-fix). So, if I start a Gnome app launcher that is prepended with gksudo, nothing appears to happen until I swipe my finger and then the app gets launched. That's cool and all, but there are times (esp. when multi-tasking) when I forget to swipe and then go "what happened to xxxxx? oh yeah..."

Anyway... does anyone have an idea of what I can do to get the dialog to appear?

thanx

--[[User:JELaVallee|JELaVallee]] 05:56, 20 February 2006 (CET)

The gksudo problem is a restriction from the X server. It doesn't allow to grab the display for other users than the logged-in one. And the pam_bioapi is invoked as root.

Is the above necessary? I just made a debian package of xscreensaver with the patch applied, and when using the bioapi debian pacakge from [http://www.qrivy.net/~michael/temp/ Michael R. Crusoe's site] which has this directory put in /usr/var/bioapi I had not to change the permissions to world-writeable there. Write access to the logfile and usb device are necessary, but that directory works with 755 as well (even though it comes with 777 in Michael's package), and all files and subdirectories are 644/755 too.

== using absolute paths for commands ==

I don't know whether using absolute paths in the articles is a good idea, at least not for tools like {{cmd|lsusb|}} which are not established utilities (i.e. used for more than a decade or something ;)) and happen to be in different locations in different distributions. E.g. said {{cmd|lsusb|}} resides in {{path|/usr/sbin|}} on Debian systems.

--[[User:Spiney|spiney]] 16:45, 12 Nov 2005 (CET)

I'm using debian testing and it's in {{path|/usr/bin|}}. I agree that the confusion is bad; dropping the absolute paths and adding a general note about checking {{cmd|$PATH|}} in case of problems is probably good.

== BioAPI error #3 ==

Its kind of strage it used to work with everythig (kdm,console,lock,etc)
Now it only works with kdm. It allways gives back:

pam_bioapi[8113]: Unable to initialize Bioapi framework, BioAPI error #:3.

Even when I set the right permissions on /proc/bus/usb.

I am able to run the Sample program as normal user after setting the permissions, but when I change within a user session by su I amnot able to run the Sample program a also get an error Code #3.

From an other terminal (alt+strg+Fx) I am able to run the Sample program but at the login I still get the error #3.

I cant remember to have changed anything an d bevor I was able to login in a console with my fingerprint now only kdm is working even kde lock-session
isnt working anymore.

Any suggestions ?

==Permission errors exclusive to xscreensaver==

I followed the instructions above and got everything working, including non-root programs like xscreensaver. However, the script to change usbfs permissions is finicky and fails to work with a lot of things like suspend/resume. Therefore, I switched to specifying <tt>devgid=108,devmode=0660,busgid=108,busmode=0770,listgid=108,listmode=0660</tt> as mount parameters for usbfs, where group 108 is a group I created and added my normal user to. This seems like a much better way of doing things, and it almost works. However, xscreensaver (using the newer patch) gives the familiar <tt>Unable to load BioAPI BSP with UUID of <nowiki>{</nowiki>5550454b-2054-464d-2f45-535320425350<nowiki>}</nowiki>, BioAPI error #194d.</tt> error in {{path|/var/log/auth.log|}}. I don't think this is a straightfoward permissions problem because
<ul>
<li>the permissions in {{path|/proc/bus/usb|}} are correct by inspection</li>
<li>I can write to the device file as my normal user</li>
<li>other programs like {{cmd|test_verify-pam_bioapi|}} and [http://pamtester.sourceforge.net/ {{cmd|pamtester|}}] work as my normal user</li>
<li>the weirdest one: xscreensaver works when the {{cmd|xscreensaver|}} daemon is launched from within {{cmd|strace|}}. It's still running as my normal user ({{cmd|strace|}} is not setuid root). I have absolutely no idea what would cause this. I thought it might be an environment issue, but the difference in environment between the {{cmd|strace|}} session and my normal session is trivial.</li>
</ul>

At this point I'm hoping it's something dumb, but I'm out of ideas. The {{cmd|xscreensaver|}} error is <tt>pam_authenticate (...) ==> 7 (Authentication failure)</tt>, for the record.

--[[User:keegan|keegan]]
----

Could you provide all the log lines between pam_start and pam_end when running {{cmd|xscreensaver -verbose|}}?

BTW, the idea with using the mount options for usbfs is very good, maybe you should add that info to the article page? I use the permission changing script without problems, also after resume, but the usbfs version is probably easier to set up, most people will be able to find {{path|/etc/fstab|}}.

So we've got the first attempt with {{cmd|pam_bioapi|}}, which fails immediately (no sign of the GUI fingerprint prompt, nor a "silent" chance to swipe the finger as with xdm), then the fallback to {{cmd|pam_unix|}} which succeeds. Earlier I had xscreensaver set up to only try {{cmd|pam_bioapi|}}, with essentially the same result -- it gives up on pam entirely and does unix auth itself.

I'd really like to strace the pam module and see what it's attempting to do to {{path|/proc/bus/usb|}}, but as that actually fixes the problem I'm kinda at a loss. Maybe there's some kernel option to print debugging info for usbfs? I'd be all for changing the article to suggest using mount options in {{path|/etc/fstab|}}, if it weren't for this one weird bug. Has anyone else had the same problem?

==Driver Expiring!!!==
Don't anyone notice that both betas of the UPEK driver is expiring in
about a month in the new year, Jan 1st 2006? They really mean it!
I set my computer date to next year and get a message "the driver has expired" when using fingerprint reader! This is a grave threat to our computer lifestyle, i.e. for those of us who got it working and use it
daily:)
Is there any workaround other than setting the date back a year when
new year come and wait for new driver? Is there a way to figure out where exactly in the driver it checked the date and how? The must have set it
somewhere in file libtfmessbsp.so, but it is binary and I can't figure out how to Reverse Engineer it.

Yes, the beta driver will expire. The final version (which is due REALLY soon now) will not.

== chmod 777 -R /usr/local/var/bioapi/ ==

Is the above necessary? I just made a debian package of xscreensaver with the patch applied, and when using the bioapi debian pacakge from [http://www.qrivy.net/~michael/temp/ Michael R. Crusoe's site] which has this directory put in /usr/var/bioapi I had not to change the permissions to world-writeable there. Write access to the logfile and usb device are necessary, but that directory works with 755 as well (even though it comes with 777 in Michael's package), and all files and subdirectories are 644/755 too.

I didn't get it to work anyway, but I'm curious about your Qt version(s) as it seemed to want Qt 3 when I was playing with it.

== using absolute paths for commands ==

I don't know whether using absolute paths in the articles is a good idea, at least not for tools like {{cmd|lsusb|}} which are not established utilities (i.e. used for more than a decade or something ;)) and happen to be in different locations in different distributions. E.g. said {{cmd|lsusb|}} resides in {{path|/usr/sbin|}} on Debian systems.

--[[User:Spiney|spiney]] 16:45, 12 Nov 2005 (CET)
----

I'm using debian testing and it's in {{path|/usr/bin|}}. I agree that the confusion is bad; dropping the absolute paths and adding a general note about checking {{cmd|$PATH|}} in case of problems is probably good.

== BioAPI error #3 ==

Its kind of strage it used to work with everythig (kdm,console,lock,etc)
Now it only works with kdm. It allways gives back:

pam_bioapi[8113]: Unable to initialize Bioapi framework, BioAPI error #:3.

Even when I set the right permissions on /proc/bus/usb.

I am able to run the Sample program as normal user after setting the permissions, but when I change within a user session by su I amnot able to run the Sample program a also get an error Code #3.

From an other terminal (alt+strg+Fx) I am able to run the Sample program but at the login I still get the error #3.

I cant remember to have changed anything an d bevor I was able to login in a console with my fingerprint now only kdm is working even kde lock-session
isnt working anymore.

Any suggestions ?

==Permission errors exclusive to xscreensaver==

I followed the instructions above and got everything working, including non-root programs like xscreensaver. However, the script to change usbfs permissions is finicky and fails to work with a lot of things like suspend/resume. Therefore, I switched to specifying <tt>devgid=108,devmode=0660,busgid=108,busmode=0770,listgid=108,listmode=0660</tt> as mount parameters for usbfs, where group 108 is a group I created and added my normal user to. This seems like a much better way of doing things, and it almost works. However, xscreensaver (using the newer patch) gives the familiar <tt>Unable to load BioAPI BSP with UUID of <nowiki>{</nowiki>5550454b-2054-464d-2f45-535320425350<nowiki>}</nowiki>, BioAPI error #194d.</tt> error in {{path|/var/log/auth.log|}}. I don't think this is a straightfoward permissions problem because
<ul>
<li>the permissions in {{path|/proc/bus/usb|}} are correct by inspection</li>
<li>I can write to the device file as my normal user</li>
<li>other programs like {{cmd|test_verify-pam_bioapi|}} and [http://pamtester.sourceforge.net/ {{cmd|pamtester|}}] work as my normal user</li>
<li>the weirdest one: xscreensaver works when the {{cmd|xscreensaver|}} daemon is launched from within {{cmd|strace|}}. It's still running as my normal user ({{cmd|strace|}} is not setuid root). I have absolutely no idea what would cause this. I thought it might be an environment issue, but the difference in environment between the {{cmd|strace|}} session and my normal session is trivial.</li>
</ul>

At this point I'm hoping it's something dumb, but I'm out of ideas. The {{cmd|xscreensaver|}} error is <tt>pam_authenticate (...) ==> 7 (Authentication failure)</tt>, for the record.

--[[User:keegan|keegan]]

Could you provide all the log lines between pam_start and pam_end when running {{cmd|xscreensaver -verbose|}}?

BTW, the idea with using the mount options for usbfs is very good, maybe you should add that info to the article page? I use the permission changing script without problems, also after resume, but the usbfs version is probably easier to set up, most people will be able to find {{path|/etc/fstab|}}.

So we've got the first attempt with {{cmd|pam_bioapi|}}, which fails immediately (no sign of the GUI fingerprint prompt, nor a "silent" chance to swipe the finger as with xdm), then the fallback to {{cmd|pam_unix|}} which succeeds. Earlier I had xscreensaver set up to only try {{cmd|pam_bioapi|}}, with essentially the same result -- it gives up on pam entirely and does unix auth itself.

I'd really like to strace the pam module and see what it's attempting to do to {{path|/proc/bus/usb|}}, but as that actually fixes the problem I'm kinda at a loss. Maybe there's some kernel option to print debugging info for usbfs? I'd be all for changing the article to suggest using mount options in {{path|/etc/fstab|}}, if it weren't for this one weird bug. Has anyone else had the same problem?

==Driver Expiring!!!==
Don't anyone notice that both betas of the UPEK driver is expiring in
about a month in the new year, Jan 1st 2006? They really mean it!
I set my computer date to next year and get a message "the driver has expired" when using fingerprint reader! This is a grave threat to our computer lifestyle, i.e. for those of us who got it working and use it
daily:)
Is there any workaround other than setting the date back a year when
new year come and wait for new driver? Is there a way to figure out where exactly in the driver it checked the date and how? The must have set it
somewhere in file libtfmessbsp.so, but it is binary and I can't figure out how to Reverse Engineer it.

---Jiang

Yes, the beta driver will expire. The final version (which is due REALLY soon now) will not.

Sumedha

Any news? Just 9 days left to expiry. --[[User:Thinker|Thinker]] 21:36, 22 Dec 2005 (CET)

The final is out, get it at [http://www.upek.com/support/dl_linux_bsp.asp UPEK's download page]. And how does one edit the industry watch section of the main page?

--[[User:Spiney|spiney]] 21:39, 22 Dec 2005 (CET)

Ah, great! Both the article page and the driver page it points to are out of date... For the news, just follow the "[[ThinkWiki:News|News]]" link in the main page.

--[[User:Thinker|Thinker]] 21:44, 22 Dec 2005 (CET)

As this is now very soon I've updated the article page to link to the final driver, which is better in a few ways anyway. This is unless anyone minds (are there any unresolved issues with the final that don't exist in the betas?).

== Updated xscreensaver patch ==

I've tried to address some usability issues with the old patch, e.g. that it calls the PAM bioapi module twice before falling back to the normal authentication methods. It can be found on my [http://linux.spiney.org/debian_gnu_linux_on_an_ibm_thinkpad_t43p_fingerprint_reader Fingerprint Reader] page, feedback is very welcome.

== Fingerprint or password ==

Is there any way to have PAM accept either a password or a finger swipe, right away? Sometimes one is more convenient, sometimes the other, so and it's a lot of trouble to wait for the UPEK scanner prompt and then cancel it in order to reach the password entry.

==xscreensaver 4.23+fingerprint.patch causes xscreensaver-gl to crash kernel==

I've gotten bioapi and 'Sample' to allow me to enroll my fingerprint, and I've also experienced the 'two logon' issue.

I compiled xscreensaver 4.23 (though it seemed that apt came with 4.24) and applied the patch. My goal was to have the fingerprint prompt come up and to see the "bad image" of the fingerprint scan.

The first time I did this, xscreensaver-gl took a dump and was causing kernel crashes. So I went and got the newest xscreensaver source and patches, and applied the bioapi patch to those. It worked (meaning it didnt crash the kernel anymore ;b )

It would seem that there is a /etc/pam.d/xscreensaver, so I commented everything out of that except the bioapi line.

Locking xscreensaver, then attempting to unlock didnt show me any fingerprint requirements, and my password didnt work.

I'm wondering if theres something that was left out of the xscreensaver howto? or if theres anyone out there who's gotten the xscreensaver portion of this to work, who would be willing to help me out :)

== gdm hangs on kde logout ==

Hi.

I am using a Thinkpad t43, installed with gentoo.
I run gdm as the login manager, with kde 3.4 and enlightenment dr16 as the window manager.

I followed the steps in the wiki, and the biometric scanner is now working fine, appart from the fact that when I close/end the session I just get a blank screen, in place of the gdm login screen.

Disabling the biometrics (by setting the pam.d file back to their originals), the session ends fine. I do this for a few times, and then set the biometrics back again, and it work fine for a few logouts, and then back to the blank screen again.

I can do ctrl+shift+f1 to get to a console window and from there I can issue a shutdown.
Although this works ok, it is a bit of a pain.

Any ideas ?

== 'gksudo' Doesn't show biopam finger swipe prompt... ==

Hey all,

First off... this is an excellent how-to! I have no real interest in using fingerprint scanner with xscreensaver, but it was up and working with everything else on my system pretty much effortlessly.

I'm running Ubuntu Breezy Badger 5.10 on an IBM T43p (2678) and have run into two oddities:
1) /etc/pam.d/xscreensaver - as it is initially configured, if you have an xscreensaver session set to require password (or xlock with screensaver) then you get prompted for the normal text-password entry and then will be prompted to swipe your finger... This is easily fixed by commenting out the '@include common-auth' line in /etc/pam.d/xscreensaver and adding the line 'auth required pam_unix.so nullok_secure'. After that change it only prompts for the text-password entry challenge.

2) gksudo - This is more of a pain... I can use the fingerprint scanner with gksudo, but gksudo doesn't prompt with the (ugly-but-functional) finger swipe dialog the way that gdm does during login or xscreensaver does when configured as mentioned above (pre-fix). So, if I start a Gnome app launcher that is prepended with gksudo, nothing appears to happen until I swipe my finger and then the app gets launched. That's cool and all, but there are times (esp. when multi-tasking) when I forget to swipe and then go "what happened to xxxxx? oh yeah..."

Anyway... does anyone have an idea of what I can do to get the dialog to appear?

thanx

--[[User:JELaVallee|JELaVallee]] 05:56, 20 February 2006 (CET)

The gksudo problem is a restriction from the X server. It doesn't allow to grab the display for other users than the logged-in one. And the pam_bioapi is invoked as root.

--[[User:Whoopie|Whoopie]] 13:10, 20 February 2006 (CET)

That makes sense... so, now I have to wonder, is there a patchable work-around like the xscreensaver one that could allow for this to work? Where should I research such? gksu's project or is this more an issue at the X11-level?

--[[User:JELaVallee|JELaVallee]] 19:38, 27 February 2006 (CET)

I got it working. Grab out the newer pam-bioapi from CVS (http://savannah.nongnu.org/cvs/?group=pam-bioapi). This version supports "multi-finger" when using the sqlite3 database. And it supports defining the used display.
Change your line in your /etc/pam.d/ files like this:

auth sufficient pam_bioapi.so {5550454b-2054-464d-2f45-535320425350} /etc/bioapi/pam/bioshadow.db :0

--[[User:Whoopie|Whoopie]] 14:27, 1 March 2006 (CET)

Very cool... Did you run into any issues rebuilding/installing this? I'll give it a shot this evening... THANKS!

--[[User:JELaVallee|JELaVallee]] 21:07, 1 March 2006 (CET)

Invoke 'xhost +local:' should be able to let gksudo work. Or just blindly sweap the finger. ;)

== Multifinger ==

Wow, theres a new version of pam_bioapi which supports multifinger enrollment and user identification.
I'll break my system with that this evening :)

Yes, but I'm searching the patch for xdm. The download page from Josef Hajas (http://nax.hn.org/pub/bioapi/) is down. Does anybody have it?

|style="vertical-align:top" |
This page describes the process of getting the [[Integrated Fingerprint Reader|integrated fingerprint reader]] to work under Linux. It is based on experiences in {{Ubuntu}} on a T43. The same works on {{Fedora}} 4, SuSE 9.3, SuSE 10, and {{Gentoo}}.
|}

==Basic installation==
===Installing the bioapi framework===
====Automated installation script====
The [[Script for enabling the fingerprint reader]] automates the installation of most components (bioapi framework, driver, pam_bioapi, pam setup, device permissions, pamtester and enrolling), for some Linux distributions.

====Binary packages====
=====Debian=====
*If you're using {{Debian}} Sid (the unstable branch) you can try the packages from Michael R. Crusoe's site, either [http://www.qrivy.net/~michael/temp/ version 1.2.3] (recommended) or [http://www.qrivy.net/~michael/debs/unstable/ older versions] which might not work with the steps in this howto.
*This seems to work for {{Ubuntu}} Breezy/Dapper too, so save yourself some trouble and grab it.
=====Gentoo=====
You can either grab the [http://www.qrivy.net/~michael/blua/bioapi/bioapi-1.2.2.ebuild.tar.bz2 ebuild], or use the source-install procedure below.

Also see [http://toe.ch/~tsa/ibm-fingerprint/ http://toe.ch/~tsa/ibm-fingerprint/] for alternative documentation on installing on Gentoo including ebuilds for all the packages used.

====Installing from source====
*Get the bioapi source:
:{{cmduser|wget http://www.qrivy.net/~michael/blua/bioapi/bioapi-latest.tar.bz2}}
*I could not compile bioapi with the graphical Qt tools. To do it manually, do the following:
:{{cmduser|tar xjf bioapi-latest.tar.bz2}}
:{{cmduser|cd bioapi-1.2.2}}
:{{cmduser|1=./configure --with-Qt-dir=no}}
:{{cmduser|make}}
:and then as root
:{{cmdroot|make install}}
:If make install fails, be sure you're root and then:
:{{cmdroot|1=export LD_LIBRARY_PATH=/usr/local/lib}}
:{{cmdroot|make install}}
:and if you want to compile pam_bioapi for auth later
:{{cmdroot|cp include/bioapi_util.h include/installdefs.h imports/cdsa/v2_0/inc/cssmtype.h /usr/include}}
:Be aware that checkinstall will not work!
:(I got through configure with Qt, but got a cryptic build error. It all worked fine with Qt disabled as above)
:buzz: This is due to a wrong qt include path, set it manually in configure and everything should work.
* By default, bioapi will install numerous files in {{path|/usr/local/<nowiki>{</nowiki>bin,lib,include<nowiki>}</nowiki>}}, including files with "self-explanatory" names such as {{path|/usr/local/bin/Sample}}. To prevent this pollution:
:Create a dedicated directory, for example {{path|/opt/bioapi}} .
:Append <tt>--prefix=/opt/bioapi</tt> to the above <tt>./configure</tt> command.
:Append {{path|/opt/bioapi/bin}} to <tt>$PATH</tt> and {{path|/opt/bioapi/lib}} to <tt>$LD_LIBRARY_PATH</tt>.
:When installing the driver (below), tell it the new install path: {{cmdroot|sh install.sh /opt/bioapi/lib}}

====Adjusting ldconfigs library search path====
At least on {{Fedora}} or {{Aurox}} 11, you may need to add {{path|/usr/local/lib}} to the library path so that the libraries referenced from <tt>pam_bioapi.so</tt> get picked up properly. The usual way to do this is adding it to the ldconfig configuration:
:{{cmdroot|echo '/usr/local/lib' > /etc/ld.so.conf.d/bioapi.conf}}
:{{cmdroot|ldconfig}}
Alternatively you can add it to the LD_LIBRARY variable.

If you see bioapi libs in the output of
:{{cmdroot|ldconfig -p | grep bioapi}}
then it should work.

===Installing and configuring the driver===
====Installing the driver====
*Download {{path|TFMESS_BSP_LIN_1.0.zip}} from the [http://www.upek.com/support/dl_linux_bsp.asp UPEK support site] and unzip it into a seperate folder, as it will not create one.
*Change to that folder and do as root:
:{{cmdroot|sh install.sh}}
:If you're running Gentoo, use
:{{cmdroot|sh install.sh /usr/lib}}
:If that fails, it may be that make install failed up above -- try setting LD_LIBRARY_PATH, do the make install again, and come back here and try this again. You also need {{cmd|mod_install|}} from bioapi in your PATH.
====Configuring permissions for non-root use====
If you want to use PAM-aware applications like xscreensaver that are NOT running with root permissions (as opposed to login, gdm or other authentication mechanisms), you may need to do all or at least some of the things in this section. More details on what is necessary on which distributions would be greately appreciated.
*Create two groups, one for access to BioAPI files and the other for access to the usb files. (This is done for full generality; i.e., you may have other USB devices which you want accessable to other users, without exposing your BioAPI configuration to them). Add your normal user (the one you wish to use PAM-aware applications with) to both of these groups.
On {{Debian}} this is done with
:{{cmdroot|addgroup --system bioapi}}
:{{cmdroot|addgroup --system usbfs}}
:{{cmdroot|adduser yournormaluser bioapi}}
:{{cmdroot|adduser yournormaluser usbfs}}
On {{SUSE}} this is done with
:{{cmdroot|groupadd --system bioapi}}
:{{cmdroot|groupadd --system usbfs}}
:{{cmdroot|groupmod -A yournormaluser bioapi}}
:{{cmdroot|groupmod -A yournormaluser usbfs}}
On {{Mandriva}} this is done with
:{{cmdroot|groupadd -r bioapi}}
:{{cmdroot|groupadd -r usbfs}}
:{{cmdroot|usermod -G bioapi,usbfs yournormaluser}}

:(where {{cmd|yournormaluser|}} is your normal user name). You will need to log out and log back in for this to take effect.
*Set permissions on the BioAPI config/registry directory:
:{{cmdroot|chown -R root:bioapi /usr/local/var/bioapi/}}
:{{cmdroot|chmod -R 770 /usr/local/var/bioapi/}}
:(change this path if you used an alternate BioAPI install directory above)
*Set permissions on the files in {{path|/proc/bus/usb}}:
:{{cmdroot|chown -R root:usbfs /proc/bus/usb}}
:{{cmdroot|chmod -R g+X /proc/bus/usb}}
:{{cmdroot|chown root:usbfs /proc/bus/usb/`lsusb <nowiki>|</nowiki> sed -ne "/0483:2016/s/Bus\ $.*$\ Device\ $.*$:\ .*/\1\/\2/p"`}}
:{{cmdroot|chmod 660 /proc/bus/usb/`lsusb <nowiki>|</nowiki> sed -ne "/0483:2016/s/Bus\ $.*$\ Device\ $.*$:\ .*/\1\/\2/p"`}}
:You may need to replace {{cmd|lsusb|}} with its full path, which is something like {{cmd|/sbin/lsusb|}} or {{cmd|/usr/bin/lsusb|}} depending on your distro. It might be necessary to put these lines into a script which is run at startup and resume from suspend/hibernate.
*As an alternative to the {{cmd|chown|}}/{{cmd|chmod|}} commands above, you can set mount options for usbfs with a line in {{path|/etc/fstab|}}; an example would be
none /proc/bus/usb usbfs defaults,devgid=108,devmode=0660,busgid=108,busmode=0770,listgid=108,listmode=0660 0 0
:where 108 is replaced with the numerical group ID of the usbfs group (you can determine this with something like {{cmd|cat /etc/group <nowiki>|</nowiki> grep usbfs <nowiki>|</nowiki> cut -d':' -f 3|}}). Make sure you only have one {{path|/proc/bus/usb}} entry in {{path|/etc/fstab}}. See the {{cmd|mount(8)|}} manpage for more information on these options. This is "cleaner" but seems to have a few weird issues -- see the talk page for details.
*You may also have files in {{path|/dev/bus/usb}}, which the driver will try before {{path|/proc/bus/usb}}. If this is another usbfs mount point ({{cmd|mount|}} shows a line containing {{cmdresult|/dev/bus/usb type usbfs}}), then simply follow the above instructions with {{path|/dev/bus/usb}} rather than {{path|/proc/bus/usb}}. Otherwise, you may be running a new kernel (i.e. 2.6.15) that makes usbfs-like files available through {{path|/dev/bus/usb}}. On systems running udev these files are dynamically created; you can configure their permissions by editing a udev config file. On Debian this is done by changing the <tt>usb_device</tt> line of {{path|/etc/udev/permissions.rules}} to read
SUBSYSTEM=="usb_device", MODE="0660", GROUP="usbfs"
*For the beta versions only, there is a logfile, which needs to exist with the proper permissions:
:{{cmdroot|touch /var/log/BSP.log && chown root:bioapi /var/log/BSP.log && chmod 660 /var/log/BSP.log}}

====Miscellaneous configuration====
* To increase the security level (minimize false accept rate), set this in {{path|/etc/tfmessbsp.cfg}}:
security-level="5"

===Testing the driver and enrolling a fingerprint===
To test the driver and generate the file containing your fingerprint information, you need a sample program included with the driver. The compilation steps below were discovered by trial and error; if they don't work for you, try the binary {{cmd|Sample|}} utility that came with the beta versions of the driver (i.e., {{path|TFMESS_BSP_LIN_1.0beta2.zip}} as mentioned above).
Go to the folder where you extracted {{path|TFMESS_BSP_LIN_1.0.zip}} and do:
:{{cmdroot|cd NonGUI_Sample}}
:Edit {{path|main.c|}} and remove (or comment out) the line
#include "port/bioapi_port.h"
:{{cmdroot|gcc -o Sample main.c -L/usr/local/lib -lbioapi100 -DUNIX -DLITTLE_ENDIAN}}
:{{cmdroot|./Sample}}
:Note that Sample may only run as root, unless you've already configured the usbfs file permissions.
:You can try to "e"nroll (to record a fingerprint for an account) and then "v"erify (to test a fingerprint against the one it expects for an account).
:You'll save a step later if you use your own login username as the username to enroll here.

==Login via pam_bioapi==

The following explains how to add fingerprint authentiation to programs that use the PAM (Pluggable Authentication Modules) framework, such as Gnome's GDM and KDE's KDM and screensaver.

===Getting required libs & tools===
====Installing pam_bioapi====
*Prerequisites
:On SuSE 10, I needed to install the pam-devel RPM
:In general, you will need pam itself (standard for most distros) as well as the pam development files (probably an optional package for your distro).
*Get and compile the pam_bioapi module.
:{{cmduser|wget http://www.qrivy.net/~michael/blua/pam_bioapi/pam_bioapi-latest.tar.bz2}}
:{{cmduser|tar xjf pam_bioapi-latest.tar.bz2}}
:{{cmduser|cd pam_bioapi-0.2.1}}
:{{cmduser|wget http://badcode.de/downloads/fingerprint.patch}}
:{{cmduser|patch -p0 < fingerprint.patch}}
:If you want to, review the patch. In general you should review all code you download and compile, if possible. The patch comes from [http://linuxbiometrics.com/modules/newbb/viewtopic.php?viewmode=flat&topic_id=80&forum=1 this thread].
:{{cmduser|./configure && make}}
:and as root
:{{cmdroot| make install}}
:{{cmdroot| cp /usr/local/lib/security/* /lib/security/}}
{{NOTE|If you get a 'rpl_malloc' error in /var/log/auth.log when trying to use the fingerprint reader, redo these steps and remove the related term from Makefile after running ./configure. (FC3, Debian etch)}}
*Use the sample tool from the fingerprint reader to create {{path|<username>.bir}} (<tt><username></tt> '''must''' be the username you want to login with. gdm will probably break for any login name that has no .bir file).
*As root do:
:{{cmdroot|SERIAL<nowiki>=`BioAPITest | sed -ne "/Fingerprint/{n;n;s/^.*: $.\{9\}$$.\{4\}$$.\{4\}$$.\{4\}$$.*$/\1-\2-\3-\4-\5/gp}"` </nowiki>}}
:{{cmdroot|echo $SERIAL}} should print something like {{cmdresult|<nowiki>{5550454b-2054-464d-2f45-535320425350}</nowiki>}} now.
:If it does, do:
:{{cmdroot|mkdir -p /etc/bioapi/pam/$SERIAL}}
:{{cmdroot|cp <username>.bir /etc/bioapi/pam/$SERIAL}}
:If not, you might just try
:{{cmdroot|SERIAL<nowiki>={5550454b-2054-464d-2f45-535320425350}</nowiki>}}
:as this value is hardcoded into the UPEK docs.

===Configuring pam===
The following part is distribution specific. On {{Ubuntu}} or {{SUSE}} you can modify {{path|/etc/pam.d/common-auth}} (on {{Gentoo}} and {{Fedora}} it is {{path|/etc/pam.d/system-auth}}) to look like this:

#
# /etc/pam.d/common-auth - authentication settings common to all services
#
# This file is included from other service-specific PAM config files,
# and should contain a list of the authentication modules that define
# the central authentication scheme for use on the system
# (e.g., /etc/shadow, LDAP, Kerberos, etc.). The default is to use the
# traditional Unix authentication mechanisms.
#
auth sufficient pam_bioapi.so {5550454b-2054-464d-2f45-535320425350} /etc/bioapi/pam/
password sufficient pam_bioapi.so {5550454b-2054-464d-2f45-535320425350} /etc/bioapi/pam/
auth required pam_unix.so nullok_secure

----
{{path|/etc/pam.d/system-auth}} for '''Gentoo'''-Users:

auth sufficient pam_bioapi.so {5550454b-2054-464d-2f45-535320425350} /etc/bioapi/pam/
password sufficient pam_bioapi.so {5550454b-2054-464d-2f45-535320425350} /etc/bioapi/pam/
auth required pam_unix.so nullok_secure
auth required pam_env.so
auth sufficient pam_unix.so likeauth nullok
auth required pam_deny.so
account required pam_unix.so
password required pam_cracklib.so difok=2 minlen=8 dcredit=2 credit=2 retry=3
password sufficient pam_unix.so nullok md5 shadow use_authtok
password required pam_deny.so
session required pam_limits.so
session required pam_unix.so
----

With this modification pam immediately starts to use the fingerprint reader to do local authorization (e.g. sudo/gdm use the fingerprint reader).

''Note:'' With a system-auth like above, '''Gentoo''' will give you 'account expired' errors.
CREATE {{path|/etc/pam.d/common-auth}} like so.

account required pam_unix.so
auth sufficient pam_bioapi.so {5550454b-2054-464d-2f45-535320425350} /etc/bioapi/pam/
password sufficient pam_bioapi.so {5550454b-2054-464d-2f45-535320425350} /etc/bioapi/pam/
auth required pam_unix.so nullok_secure
session required pam_limits.so
session required pam_unix.so

{{WARN|If su/sudo expects to receive the root password (SuSE 10), you need to have fingerprint settings for root (that is, copy in a root.bir as well as a your-username.bir). Otherwise, they get a segmentation fault. Which is a little unfortunate, given that you need to su or sudo to change your settings...}}

Note that sshd may pick up the fingerprint settings from {{path|/etc/pam.d/common-auth}}. I didn't want that, so I removed the "auth include common-auth" line from {{path|/etc/pam.d/sshd}} and replaced it with the lines that were originally in my {{path|/etc/pam.d/common-auth}}. That way most local services use the fingerprint reader, but sshd does not.

Another way to do this is to create a file ({{path|/etc/pam.d/bioapi|}} for example) which contains the {{cmd|pam_bioapi.so|}} lines, and explicitly {{cmd|@include|}} this '''before''' {{path|/etc/pam.d/common-auth|}} in the files for services which should use the fingerprint reader. In this case you should leave {{path|/etc/pam.d/common-auth|}} alone.

{{NOTE|This was discovered through trial and success, if it is plain wrong, wikorrect it, please.}}

In {{Fedora}} the original 'session' terms in {{path|/etc/pam.d/system-auth}} need to be kept.

{{HINT|The setup described above will/could affect remote ssh logins to also use biometric logins, which is a bit silly (who wants to remote ssh to the laptop, and then have to walk over to it and swipe your finger) To avoid that you can copy the default <tt>/etc/pam.d/system-auth</tt> to <tt>/etc/pam.d/sshd</tt> which will allow the sshd service to use the standard authentication procedure.}}

You can do some useful testing with [http://pamtester.sourceforge.net/ {{cmd|pamtester|}}], which calls the pam modules as if it were a program of your choice. Examples:
:{{cmdroot|pamtester xdm yourusername authenticate}}
:{{cmduser|pamtester xscreensaver yourusername authenticate}}
where {{cmd|yourusername|}} is your username. Note that {{cmd|pamtester|}} should run as root if and only if the program in question does.

===Application support===
The implementation of fingerprint scanning support in the relevant applications varies.

Here is the behaviour of the most common ones:
* gdm should pop up an (ugly) image to swipe your finger and... magic - you can login without a password.
* kdm doesn't give any visual indication, other than that the cursor stops blinking. Just swipe your finger and hope it lets you log in.
* In xdm, enter your username and a blank password, then swipe (there is no popup as well).
* The KDE screen saver in SUSE 10 requires you to enter an empty password (or select the correct user and then enter an empty password) in order to get the fingerprint prompt.
* For Fedora users, the redhat-config tools will crash if no root.bir presents. Also, there won't be any visual idication unless X server is properly configured for root to access. Just swipe your finger when the HDD stopped blinking or issue the following command in advance:
:{{cmduser|xhost +local:}}

==Make xscreensaver use the scanner==
*Get the needed xscreensaver sources:
:{{cmduser|wget http://www.jwz.org/xscreensaver/xscreensaver-4.23.tar.gz}}
:{{cmduser|tar xzf xscreensaver-4.23.tar.gz}}
:{{cmduser|cd xscreensaver-4.23}}
:{{cmduser|wget http://nax.hn.org/pub/bioapi/xscreensaver-4.22_alternativeAuth.diff}}
*After reviewing the patch (it's small and straightforward), do
:{{cmduser|patch -p1 < xscreensaver-4.22_alternativeAuth.diff}} The patch prevents xscreensaver from opening an authentification window and dispatches the authentification request to another program, in our case <tt>pam</tt> and <tt>pam_bioapi</tt>. It should apply with some offset, don't mind that. If it says something about rejected though, then there's a problem.
*Compile with
:{{cmduser|./configure --with-pam && make}} 
*If you recieve an error like "undefined reference to `XmuPrintDefaultErrorMessage'" then install the libxmu-dev package and run the previous line again
*and then install as root with
:{{cmduser|su -c make install}} .
*Make sure that the newly compiled xscreensaver is used:
:{{cmduser|which xscreensaver}} should return
:{{cmdresult|/usr/local/bin/xscreensaver}} .
:*In case it doesn't, try
::{{cmduser|1=export PATH=/usr/local/bin:$PATH}} and retry.
*Kill the running instance of xscreensaver:
:{{cmduser|xscreensaver-command -exit}}
*Make sure you have the following line in your {{path|~/.xscreensaver}}:
alternativeAuth: True
*Now edit {{path|/etc/pam.d/xscreensaver}} to include the following line (If you're on {{Ubuntu}} Breezy and you already changed {{path|/etc/pam.d/common-auth}} you should not need to do this.):
auth sufficient pam_bioapi.so {5550454b-2054-464d-2f45-535320425350} /etc/bioapi/pam/
*Start the new xscreensaver
:{{cmduser|xscreensaver}} There should be a splash screen with version 4.23.
*Now try:
:{{cmduser|xscreensaver-command -lock}}

If you have questions or problems with this procedure, ask: t43fingerprint (at) badcode.de .

===Package for Debian sid===

If you're running {{Debian}} sid (the unstable branch) you can also try the patched .deb-package (built from current Debian sources fetched with {{cmd|apt-get source|}}) from [http://linux.spiney.org/debian_gnu_linux_on_an_ibm_thinkpad_t43p_fingerprint_reader this page], which also has Debian-specific instructions on how to setup the fingerprint reader. Use it on your own risk.

==Troubleshooting and Hints==
# After installing the driver, don't forget to reboot!
## This might not be necessary. it worked here without having to reboot.
# To see if the fingerprint device is know on the USB bus do:
:{{cmdroot|lsusb}}
:as root and you should see a line like:
:{{cmdresult|Bus 003 Device 004: ID 0483:2016 SGS Thomson Microelectronics}}
:The bus and device number can be different. This should work without the driver installed. If the device does not show up, you have a hardware problem/quirk, Rebooting or removing/inserting USB kernel modules might fix this.
# For some installation, after installing the driver as in section [[#Installing the driver|Installing the driver]] and makingÂ´sure the device is recognized, try to test it by going to {{path|NonGUI_Sample}} directory and run {{cmdroot|./Sample}}, one get segmentation fault. In this case, try getting the Beta1 instead of Beta2 of the driver and installing it
# There was some confusion about the /etc/bioapi1.10/pam{5550454b-2054-464d-2f45-535320425350} path, this has been fixed in the howto, if you have problems, check the section again, the path needs to have the '-' in them
# When something goes wrong look at the tail of {{path|/var/log/auth.log}}. (on {{Fedora}} it is {{path|/var/log/secure}}) Specifically if you see an entry saying something like
pam_bioapi[10480]: Unable to load BioAPI BSP with UUID of {5550454b-2054-464d-2f45-535320425350}, BioAPI error <nowiki>#</nowiki>194d.
Check whether your {{path|/proc/bus/usb}} directory permissions are set up as in the
section [[#Installing the driver|Installing the driver]].
# To get the xscreensaver compiled you might need a bunch of header files (depending on which xscreensaver features you want), in my case I need the following:
#*python-gtk2-dev
#*libgstreamer0.8-dev
#*xlibs-dev
# Sometimes {{path|$HOME/.xscreensaver}} got overwritten, try changing it to read-only.
# If after suspending to RAM and resume, lsusb no longer have "SGS Thomson Microelectronics" entry, try adding a line
/etc/init.d/hotplug restart
to your {{path|/etc/acpi/resume.sh}} file
#If after resume lsusb shows the device but xscreensaver does not ask for fingerprint for login, you might want to check the permission of the usb bus in the appropriate {{path|/proc/bus/usb/}} entry. If necessesary you might need to add a line to {{path|/etc/acpi/resume.sh}} as in section [[#Installing the driver|Installing the driver]] to set the permission right.
-----
If it still doesn't work, ask me for help (and make sure all usefull stuff makes it back into this wiki :)
to get a starting point as to where your problem is please include the output of:

:{{cmduser|lsusb}}

:{{cmdroot|ldconfig -p <nowiki>|</nowiki> grep bioapi}}

:{{cmdroot|updatedb && locate bioapi}}

How to enable integrated fingerprint reader with BioAPI

{| width="100%"
|style="vertical-align:top;padding-right:20px;width:10px;white-space:nowrap;" | __TOC__
|style="vertical-align:top" |
This page describes the process of getting the [[Integrated Fingerprint Reader|integrated fingerprint reader]] to work under Linux. It is based on experiences in {{Ubuntu}} on a T43. The same works on {{Fedora}} 4, SuSE 9.3, SuSE 10, and {{Gentoo}}.
|}

==Basic installation==
===Installing the bioapi framework===
====Automated installation script====
The [[Script for enabling the fingerprint reader]] automates the installation of most components (bioapi framework, driver, pam_bioapi, pam setup, device permissions, pamtester and enrolling), for some Linux distributions.

====Binary packages====
=====Debian=====
*If you're using {{Debian}} Sid (the unstable branch) you can try the packages from Michael R. Crusoe's site, either [http://www.qrivy.net/~michael/temp/ version 1.2.3] (recommended) or [http://www.qrivy.net/~michael/debs/unstable/ older versions] which might not work with the steps in this howto.
*This seems to work for {{Ubuntu}} Breezy/Dapper too, so save yourself some trouble and grab it.
=====Gentoo=====
You can either grab the [http://www.qrivy.net/~michael/blua/bioapi/bioapi-1.2.2.ebuild.tar.bz2 ebuild], or use the source-install procedure below.

Also see [http://toe.ch/~tsa/ibm-fingerprint/ http://toe.ch/~tsa/ibm-fingerprint/] for alternative documentation on installing on Gentoo including ebuilds for all the packages used.

====Installing from source====
*Get the bioapi source:
:{{cmduser|wget http://www.qrivy.net/~michael/blua/bioapi/bioapi-latest.tar.bz2}}
*I could not compile bioapi with the graphical Qt tools. To do it manually, do the following:
:{{cmduser|tar xjf bioapi-latest.tar.bz2}}
:{{cmduser|cd bioapi-1.2.2}}
:{{cmduser|1=./configure --with-Qt-dir=no}}
:{{cmduser|make}}
:and then as root
:{{cmdroot|make install}}
:If make install fails, be sure you're root and then:
:{{cmdroot|1=export LD_LIBRARY_PATH=/usr/local/lib}}
:{{cmdroot|make install}}
:and if you want to compile pam_bioapi for auth later
:{{cmdroot|cp include/bioapi_util.h include/installdefs.h imports/cdsa/v2_0/inc/cssmtype.h /usr/include}}
:Be aware that checkinstall will not work!
:(I got through configure with Qt, but got a cryptic build error. It all worked fine with Qt disabled as above)
:buzz: This is due to a wrong qt include path, set it manually in configure and everything should work.
* By default, bioapi will install numerous files in {{path|/usr/local/<nowiki>{</nowiki>bin,lib,include<nowiki>}</nowiki>}}, including files with "self-explanatory" names such as {{path|/usr/local/bin/Sample}}. To prevent this pollution:
:Create a dedicated directory, for example {{path|/opt/bioapi}} .
:Append <tt>--prefix=/opt/bioapi</tt> to the above <tt>./configure</tt> command.
:Append {{path|/opt/bioapi/bin}} to <tt>$PATH</tt> and {{path|/opt/bioapi/lib}} to <tt>$LD_LIBRARY_PATH</tt>.
:When installing the driver (below), tell it the new install path: {{cmdroot|sh install.sh /opt/bioapi/lib}}

====Adjusting ldconfigs library search path====
At least on {{Fedora}} or {{Aurox}} 11, you may need to add {{path|/usr/local/lib}} to the library path so that the libraries referenced from <tt>pam_bioapi.so</tt> get picked up properly. The usual way to do this is adding it to the ldconfig configuration:
:{{cmdroot|echo '/usr/local/lib' > /etc/ld.so.conf.d/bioapi.conf}}
:{{cmdroot|ldconfig}}
Alternatively you can add it to the LD_LIBRARY variable.

If you see bioapi libs in the output of
:{{cmdroot|ldconfig -p | grep bioapi}}
then it should work.

===Installing and configuring the driver===
====Installing the driver====
*Download {{path|TFMESS_BSP_LIN_1.0.zip}} from the [http://www.upek.com/support/dl_linux_bsp.asp UPEK support site] and unzip it into a seperate folder, as it will not create one.
*Change to that folder and do as root:
:{{cmdroot|sh install.sh}}
:If you're running Gentoo, use
:{{cmdroot|sh install.sh /usr/lib}}
:If that fails, it may be that make install failed up above -- try setting LD_LIBRARY_PATH, do the make install again, and come back here and try this again. You also need {{cmd|mod_install|}} from bioapi in your PATH.
====Configuring permissions for non-root use====
If you want to use PAM-aware applications like xscreensaver that are NOT running with root permissions (as opposed to login, gdm or other authentication mechanisms), you may need to do all or at least some of the things in this section. More details on what is necessary on which distributions would be greately appreciated.
*Create two groups, one for access to BioAPI files and the other for access to the usb files. (This is done for full generality; i.e., you may have other USB devices which you want accessable to other users, without exposing your BioAPI configuration to them). Add your normal user (the one you wish to use PAM-aware applications with) to both of these groups.
On {{Debian}} this is done with
:{{cmdroot|addgroup --system bioapi}}
:{{cmdroot|addgroup --system usbfs}}
:{{cmdroot|adduser yournormaluser bioapi}}
:{{cmdroot|adduser yournormaluser usbfs}}
On {{SUSE}} this is done with
:{{cmdroot|groupadd --system bioapi}}
:{{cmdroot|groupadd --system usbfs}}
:{{cmdroot|groupmod -A yournormaluser bioapi}}
:{{cmdroot|groupmod -A yournormaluser usbfs}}
On {{Mandriva}} this is done with
:{{cmdroot|groupadd -r bioapi}}
:{{cmdroot|groupadd -r usbfs}}
:{{cmdroot|usermod -G bioapi,usbfs yournormaluser}}

:(where {{cmd|yournormaluser|}} is your normal user name). You will need to log out and log back in for this to take effect.
*Set permissions on the BioAPI config/registry directory:
:{{cmdroot|chown -R root:bioapi /usr/local/var/bioapi/}}
:{{cmdroot|chmod -R 770 /usr/local/var/bioapi/}}
:(change this path if you used an alternate BioAPI install directory above)
*Set permissions on the files in {{path|/proc/bus/usb}}:
:{{cmdroot|chown -R root:usbfs /proc/bus/usb}}
:{{cmdroot|chmod -R g+X /proc/bus/usb}}
:{{cmdroot|chown root:usbfs /proc/bus/usb/`lsusb <nowiki>|</nowiki> sed -ne "/0483:2016/s/Bus\ $.*$\ Device\ $.*$:\ .*/\1\/\2/p"`}}
:{{cmdroot|chmod 660 /proc/bus/usb/`lsusb <nowiki>|</nowiki> sed -ne "/0483:2016/s/Bus\ $.*$\ Device\ $.*$:\ .*/\1\/\2/p"`}}
:You may need to replace {{cmd|lsusb|}} with its full path, which is something like {{cmd|/sbin/lsusb|}} or {{cmd|/usr/bin/lsusb|}} depending on your distro. It might be necessary to put these lines into a script which is run at startup and resume from suspend/hibernate.
*As an alternative to the {{cmd|chown|}}/{{cmd|chmod|}} commands above, you can set mount options for usbfs with a line in {{path|/etc/fstab|}}; an example would be
none /proc/bus/usb usbfs defaults,devgid=108,devmode=0660,busgid=108,busmode=0770,listgid=108,listmode=0660 0 0
:where 108 is replaced with the numerical group ID of the usbfs group (you can determine this with something like {{cmd|cat /etc/group <nowiki>|</nowiki> grep usbfs <nowiki>|</nowiki> cut -d':' -f 3|}}). Make sure you only have one {{path|/proc/bus/usb}} entry in {{path|/etc/fstab}}. See the {{cmd|mount(8)|}} manpage for more information on these options. This is "cleaner" but seems to have a few weird issues -- see the talk page for details.
*You may also have files in {{path|/dev/bus/usb}}, which the driver will try before {{path|/proc/bus/usb}}. If this is another usbfs mount point ({{cmd|mount|}} shows a line containing {{cmdresult|/dev/bus/usb type usbfs}}), then simply follow the above instructions with {{path|/dev/bus/usb}} rather than {{path|/proc/bus/usb}}. Otherwise, you may be running a new kernel (i.e. 2.6.15) that makes usbfs-like files available through {{path|/dev/bus/usb}}. On systems running udev these files are dynamically created; you can configure their permissions by editing a udev config file. On Debian this is done by changing the <tt>usb_device</tt> line of {{path|/etc/udev/permissions.rules}} to read
SUBSYSTEM=="usb_device", MODE="0660", GROUP="usbfs"
*For the beta versions only, there is a logfile, which needs to exist with the proper permissions:
:{{cmdroot|touch /var/log/BSP.log && chown root:bioapi /var/log/BSP.log && chmod 660 /var/log/BSP.log}}

====Miscellaneous configuration====
* To increase the security level (minimize false accept rate), set this in {{path|/etc/tfmessbsp.cfg}}:
security-level="5"

===Testing the driver and enrolling a fingerprint===
To test the driver and generate the file containing your fingerprint information, you need a sample program included with the driver. The compilation steps below were discovered by trial and error; if they don't work for you, try the binary {{cmd|Sample|}} utility that came with the beta versions of the driver (i.e., {{path|TFMESS_BSP_LIN_1.0beta2.zip}} as mentioned above).
Go to the folder where you extracted {{path|TFMESS_BSP_LIN_1.0.zip}} and do:
:{{cmdroot|cd NonGUI_Sample}}
:Edit {{path|main.c|}} and remove (or comment out) the line
#include "port/bioapi_port.h"
:{{cmdroot|gcc -o Sample main.c -L/usr/local/lib -lbioapi100 -DUNIX -DLITTLE_ENDIAN}}
:{{cmdroot|./Sample}}
:Note that Sample may only run as root, unless you've already configured the usbfs file permissions.
:You can try to "e"nroll (to record a fingerprint for an account) and then "v"erify (to test a fingerprint against the one it expects for an account).
:You'll save a step later if you use your own login username as the username to enroll here.

==Login via pam_bioapi==

The following explains how to add fingerprint authentiation to programs that use the PAM (Pluggable Authentication Modules) framework, such as Gnome's GDM and KDE's KDM and screensaver.

===Getting required libs & tools===
====Installing pam_bioapi====
*Prerequisites
:On SuSE 10, I needed to install the pam-devel RPM
:In general, you will need pam itself (standard for most distros) as well as the pam development files (probably an optional package for your distro).
*Get and compile the pam_bioapi module.
:{{cmduser|wget http://www.qrivy.net/~michael/blua/pam_bioapi/pam_bioapi-latest.tar.bz2}}
:{{cmduser|tar xjf pam_bioapi-latest.tar.bz2}}
:{{cmduser|cd pam_bioapi-0.2.1}}
:{{cmduser|wget http://badcode.de/downloads/fingerprint.patch}}
:{{cmduser|patch -p0 < fingerprint.patch}}
:If you want to, review the patch. In general you should review all code you download and compile, if possible. The patch comes from [http://linuxbiometrics.com/modules/newbb/viewtopic.php?viewmode=flat&topic_id=80&forum=1 this thread].
:{{cmduser|./configure && make}}
:and as root
:{{cmdroot| make install}}
:{{cmdroot| cp /usr/local/lib/security/* /lib/security/}}
{{NOTE|If you get a 'rpl_malloc' error in /var/log/auth.log when trying to use the fingerprint reader, redo these steps and remove the related term from Makefile after running ./configure. (FC3, Debian etch)}}
*Use the sample tool from the fingerprint reader to create {{path|<username>.bir}} (<tt><username></tt> '''must''' be the username you want to login with. gdm will probably break for any login name that has no .bir file).
*As root do:
:{{cmdroot|SERIAL<nowiki>=`BioAPITest | sed -ne "/Fingerprint/{n;n;s/^.*: $.\{9\}$$.\{4\}$$.\{4\}$$.\{4\}$$.*$/\1-\2-\3-\4-\5/gp}"` </nowiki>}}
:{{cmdroot|echo $SERIAL}} should print something like {{cmdresult|<nowiki>{5550454b-2054-464d-2f45-535320425350}</nowiki>}} now.
:If it does, do:
:{{cmdroot|mkdir -p /etc/bioapi/pam/$SERIAL}}
:{{cmdroot|cp <username>.bir /etc/bioapi/pam/$SERIAL}}
:If not, you might just try
:{{cmdroot|SERIAL<nowiki>={5550454b-2054-464d-2f45-535320425350}</nowiki>}}
:as this value is hardcoded into the UPEK docs.

===Configuring pam===
The following part is distribution specific. On {{Ubuntu}} or {{SUSE}} you can modify {{path|/etc/pam.d/common-auth}} (on {{Gentoo}} and {{Fedora}} it is {{path|/etc/pam.d/system-auth}}) to look like this:

#
# /etc/pam.d/common-auth - authentication settings common to all services
#
# This file is included from other service-specific PAM config files,
# and should contain a list of the authentication modules that define
# the central authentication scheme for use on the system
# (e.g., /etc/shadow, LDAP, Kerberos, etc.). The default is to use the
# traditional Unix authentication mechanisms.
#
auth sufficient pam_bioapi.so {5550454b-2054-464d-2f45-535320425350} /etc/bioapi/pam/
password sufficient pam_bioapi.so {5550454b-2054-464d-2f45-535320425350} /etc/bioapi/pam/
auth required pam_unix.so nullok_secure

----
{{path|/etc/pam.d/system-auth}} for '''Gentoo'''-Users:

auth sufficient pam_bioapi.so {5550454b-2054-464d-2f45-535320425350} /etc/bioapi/pam/
password sufficient pam_bioapi.so {5550454b-2054-464d-2f45-535320425350} /etc/bioapi/pam/
auth required pam_unix.so nullok_secure
auth required pam_env.so
auth sufficient pam_unix.so likeauth nullok
auth required pam_deny.so
account required pam_unix.so
password required pam_cracklib.so difok=2 minlen=8 dcredit=2 credit=2 retry=3
password sufficient pam_unix.so nullok md5 shadow use_authtok
password required pam_deny.so
session required pam_limits.so
session required pam_unix.so
----

With this modification pam immediately starts to use the fingerprint reader to do local authorization (e.g. sudo/gdm use the fingerprint reader).

''Note:'' With a system-auth like above, '''Gentoo''' will give you 'account expired' errors.
CREATE {{path|/etc/pam.d/common-auth}} like so.

account required pam_unix.so
auth sufficient pam_bioapi.so {5550454b-2054-464d-2f45-535320425350} /etc/bioapi/pam/
password sufficient pam_bioapi.so {5550454b-2054-464d-2f45-535320425350} /etc/bioapi/pam/
auth required pam_unix.so nullok_secure
session required pam_limits.so
session required pam_unix.so

{{WARN|If su/sudo expects to receive the root password (SuSE 10), you need to have fingerprint settings for root (that is, copy in a root.bir as well as a your-username.bir). Otherwise, they get a segmentation fault. Which is a little unfortunate, given that you need to su or sudo to change your settings...}}

Note that sshd may pick up the fingerprint settings from {{path|/etc/pam.d/common-auth}}. I didn't want that, so I removed the "auth include common-auth" line from {{path|/etc/pam.d/sshd}} and replaced it with the lines that were originally in my {{path|/etc/pam.d/common-auth}}. That way most local services use the fingerprint reader, but sshd does not.

Another way to do this is to create a file ({{path|/etc/pam.d/bioapi|}} for example) which contains the {{cmd|pam_bioapi.so|}} lines, and explicitly {{cmd|@include|}} this '''before''' {{path|/etc/pam.d/common-auth|}} in the files for services which should use the fingerprint reader. In this case you should leave {{path|/etc/pam.d/common-auth|}} alone.

{{NOTE|This was discovered through trial and success, if it is plain wrong, wikorrect it, please.}}

In {{Fedora}} the original 'session' terms in {{path|/etc/pam.d/system-auth}} need to be kept.

{{HINT|The setup described above will/could affect remote ssh logins to also use biometric logins, which is a bit silly (who wants to remote ssh to the laptop, and then have to walk over to it and swipe your finger) To avoid that you can copy the default <tt>/etc/pam.d/system-auth</tt> to <tt>/etc/pam.d/sshd</tt> which will allow the sshd service to use the standard authentication procedure.}}

You can do some useful testing with [http://pamtester.sourceforge.net/ {{cmd|pamtester|}}], which calls the pam modules as if it were a program of your choice. Examples:
:{{cmdroot|pamtester xdm yourusername authenticate}}
:{{cmduser|pamtester xscreensaver yourusername authenticate}}
where {{cmd|yourusername|}} is your username. Note that {{cmd|pamtester|}} should run as root if and only if the program in question does.

===Application support===
The implementation of fingerprint scanning support in the relevant applications varies.

Here is the behaviour of the most common ones:
* gdm should pop up an (ugly) image to swipe your finger and... magic - you can login without a password.
* kdm doesn't give any visual indication, other than that the cursor stops blinking. Just swipe your finger and hope it lets you log in.
* In xdm, enter your username and a blank password, then swipe (there is no popup as well).
* The KDE screen saver in SUSE 10 requires you to enter an empty password (or select the correct user and then enter an empty password) in order to get the fingerprint prompt.
* For Fedora users, the redhat-config tools will crash if no root.bir presents. Also, there won't be any visual idication unless X server is properly configured for root to access. Just swipe your finger when the HDD stopped blinking or set "xhost +local:" in advance.

==Make xscreensaver use the scanner==
*Get the needed xscreensaver sources:
:{{cmduser|wget http://www.jwz.org/xscreensaver/xscreensaver-4.23.tar.gz}}
:{{cmduser|tar xzf xscreensaver-4.23.tar.gz}}
:{{cmduser|cd xscreensaver-4.23}}
:{{cmduser|wget http://nax.hn.org/pub/bioapi/xscreensaver-4.22_alternativeAuth.diff}}
*After reviewing the patch (it's small and straightforward), do
:{{cmduser|patch -p1 < xscreensaver-4.22_alternativeAuth.diff}} The patch prevents xscreensaver from opening an authentification window and dispatches the authentification request to another program, in our case <tt>pam</tt> and <tt>pam_bioapi</tt>. It should apply with some offset, don't mind that. If it says something about rejected though, then there's a problem.
*Compile with
:{{cmduser|./configure --with-pam && make}} 
*If you recieve an error like "undefined reference to `XmuPrintDefaultErrorMessage'" then install the libxmu-dev package and run the previous line again
*and then install as root with
:{{cmduser|su -c make install}} .
*Make sure that the newly compiled xscreensaver is used:
:{{cmduser|which xscreensaver}} should return
:{{cmdresult|/usr/local/bin/xscreensaver}} .
:*In case it doesn't, try
::{{cmduser|1=export PATH=/usr/local/bin:$PATH}} and retry.
*Kill the running instance of xscreensaver:
:{{cmduser|xscreensaver-command -exit}}
*Make sure you have the following line in your {{path|~/.xscreensaver}}:
alternativeAuth: True
*Now edit {{path|/etc/pam.d/xscreensaver}} to include the following line (If you're on {{Ubuntu}} Breezy and you already changed {{path|/etc/pam.d/common-auth}} you should not need to do this.):
auth sufficient pam_bioapi.so {5550454b-2054-464d-2f45-535320425350} /etc/bioapi/pam/
*Start the new xscreensaver
:{{cmduser|xscreensaver}} There should be a splash screen with version 4.23.
*Now try:
:{{cmduser|xscreensaver-command -lock}}

If you have questions or problems with this procedure, ask: t43fingerprint (at) badcode.de .

===Package for Debian sid===

If you're running {{Debian}} sid (the unstable branch) you can also try the patched .deb-package (built from current Debian sources fetched with {{cmd|apt-get source|}}) from [http://linux.spiney.org/debian_gnu_linux_on_an_ibm_thinkpad_t43p_fingerprint_reader this page], which also has Debian-specific instructions on how to setup the fingerprint reader. Use it on your own risk.

==Troubleshooting and Hints==
# After installing the driver, don't forget to reboot!
## This might not be necessary. it worked here without having to reboot.
# To see if the fingerprint device is know on the USB bus do:
:{{cmdroot|lsusb}}
:as root and you should see a line like:
:{{cmdresult|Bus 003 Device 004: ID 0483:2016 SGS Thomson Microelectronics}}
:The bus and device number can be different. This should work without the driver installed. If the device does not show up, you have a hardware problem/quirk, Rebooting or removing/inserting USB kernel modules might fix this.
# For some installation, after installing the driver as in section [[#Installing the driver|Installing the driver]] and makingÂ´sure the device is recognized, try to test it by going to {{path|NonGUI_Sample}} directory and run {{cmdroot|./Sample}}, one get segmentation fault. In this case, try getting the Beta1 instead of Beta2 of the driver and installing it
# There was some confusion about the /etc/bioapi1.10/pam{5550454b-2054-464d-2f45-535320425350} path, this has been fixed in the howto, if you have problems, check the section again, the path needs to have the '-' in them
# When something goes wrong look at the tail of {{path|/var/log/auth.log}}. (on {{Fedora}} it is {{path|/var/log/secure}}) Specifically if you see an entry saying something like
pam_bioapi[10480]: Unable to load BioAPI BSP with UUID of {5550454b-2054-464d-2f45-535320425350}, BioAPI error <nowiki>#</nowiki>194d.
Check whether your {{path|/proc/bus/usb}} directory permissions are set up as in the
section [[#Installing the driver|Installing the driver]].
# To get the xscreensaver compiled you might need a bunch of header files (depending on which xscreensaver features you want), in my case I need the following:
#*python-gtk2-dev
#*libgstreamer0.8-dev
#*xlibs-dev
# Sometimes {{path|$HOME/.xscreensaver}} got overwritten, try changing it to read-only.
# If after suspending to RAM and resume, lsusb no longer have "SGS Thomson Microelectronics" entry, try adding a line
/etc/init.d/hotplug restart
to your {{path|/etc/acpi/resume.sh}} file
#If after resume lsusb shows the device but xscreensaver does not ask for fingerprint for login, you might want to check the permission of the usb bus in the appropriate {{path|/proc/bus/usb/}} entry. If necessesary you might need to add a line to {{path|/etc/acpi/resume.sh}} as in section [[#Installing the driver|Installing the driver]] to set the permission right.
-----
If it still doesn't work, ask me for help (and make sure all usefull stuff makes it back into this wiki :)
to get a starting point as to where your problem is please include the output of:

:{{cmduser|lsusb}}

:{{cmdroot|ldconfig -p <nowiki>|</nowiki> grep bioapi}}

:{{cmdroot|updatedb && locate bioapi}}

== Installation ==

The {{X41T}} requires a dock to use an optical drive. The BIOS can, however, boot from USB or the network.

=== Preparation ===

The {{X41T}} comes installed with Windows XP Tablet edition. Before installing {{Fedora}}, the harddrive needs to be repartitioned and certain parameters need to be written down for later use.

# Use Powerquest Partition Magic, QTParted or some software that can partition a basic disk with NTFS partitions to create room for Fedora Core 4.
# Under windows, note the serial port and the irq used by the Wacom stylus device. This information is listed under {{path|Control Panel > System > Hardware > Device Manager > HID > Wacom Stylus > Resources}}. On the 18695CU model, the port is 0200-0207 and irq is 5.
# Note the MAC address of the ethernet card and the wireless card. These are on a stickers under the laptop labled LAN MAC Address and 802.11b/g MAC Address.

=== USB Boot Preparation ===

From the Fedora Core 4 DVD, write the bootimage to a USB device.

dd if=images/diskboot.img of=/dev/sdb

where {{path|/dev/sdb}} is the USB device. '''Note:''' The destination is {{path|/dev/sdb}} and not {{path|/dev/sdb1}}. Also perhaps due to a BIOS problem or image problem, USB booting may not always work.

=== PXE Boot Preparation ===

PXE boot requires the X41 Tablet to be connected to a wired ethernet network that is configured for DHCP and TFTP. This can be accomplished by connecting the tablet to another host over a ethernet corssover cable.

Configure the DHCP server to hand out boot instructions. In the {{path|/etc/dhcpd.conf}} file, include:

host pxeclient {
hardware ethernet ''00:0a:e4:35:a9:12''; # X41 Tablet LAN MAC Adress noted above
filename "/pxelinux.0";
fixed-address ''192.168.1.60''; # IP Address for X41 Tablet
next-server ''192.168.1.1''; # IP Address of TFTP server
}

'''Note:''' Replace the ''italicized'' fields above with appropriate values for your hardware. A sample dhcpd.conf file can be found here.

Configure the TFTP server. If the TFPT server uses xinetd, you may need to enable it in {{path|/etc/xinetd.d/tftp}} by setting <code>disable = no</code>. Also note root of the server. This is usually {{path|/tftpboot}}. Copy the pxelinux files present on the FC4 disk in {{path|images/pxelinux/}} to the TFTP root. You will need two additional files [http://www.cs.cornell.edu/~saikat/pxelinux.0 {{path|pxelinux.0}}] and {{path|pxelinux.cfg/default}}.

:{{cmduser|find /tftpboot}}
:{{cmdresult|/tftpboot}}
:{{cmdresult|/tftpboot/pxelinux.0}}
:{{cmdresult|/tftpboot/initrd.img}}
:{{cmdresult|/tftpboot/vmlinuz}}
:{{cmdresult|/tftpboot/pxelinux.cfg}}
:{{cmdresult|/tftpboot/pxelinux.cfg/default}}

Contents of {{path|/tftpboot/pxelinux.cfg/default}}:
DEFAULT vm
SERIAL 0 9600
label vm
kernel vmlinuz
append initrd=initrd.img ramdisk_size=9372 root=/dev/rd/0

=== Installing ===

Restart the X41 Tablet. If you are using a USB key, insert it before switching on the tablet. Press {{key|F12}} during startup to display the temporary boot device screen. Select either USB HDD or Netowkr Boot based on your medium of choice. This should bring up the Fedora Core installer. Once the installer has started up, Fedora Core can be installed over the web, ftp, nfs, USB disk etc. The rest of the installation is straight forward and described in detail here.

{{NOTE|There may be some screen corruption or shimmering effects in the graphical installer. This can be fixed after installation is complete as explained in the X Server Configuration below.}}

== Configuration ==

=== X Server ===

The X41 Tablet, uses an Intel integrated 915 video device. This is supported by the '''i810''' driver and can be selected from the graphical xserver screen by selecting the ''Intel 915'' option. '''Note:''' The <tt>i810</tt> driver on <tt>xorg-6.8.2</tt> and earlier '''DO NOT''' support the card. Use the <tt>vesa (generic)</tt> option for such servers. The LCD screen is a <tt>1024x768</tt> display. The stylus requires the <tt>linuxwacom</tt> package. This should automatically be installed as part of FC4. If you update FC4 with the latest rpms the i810 driver will work. You can use <tt>system-config-display</tt> to change the driver, but do it before adding configuration for stylus since it will drop the stylus related settings. For some additional information about rotating the screen and installing FC4 see http://www.dklevine.com/general/software/tc1000/x41f4.html

{{NOTE|
# The first time <tt>vesa (generic)</tt> is selected, there may appear to be some screen corruption or shimmering effects. It should go away after a reboot.
# The stylus may not work as a mouse immidiately. See the Stylus section below.
# Screen rotation on-the-fly currently does ''not'' work. It may be possible to pass a kernel parameter at boot time to rotate the framebuffer into a portrait orientation, but this has not been confirmed.

=== Stylus ===

The stylus is not recognized in Fedora Core at startup. Connect {{path|/dev/ttyS0}} to the stylus by including the following line in {{path|/etc/rc.d/rc.local}}.

setserial /dev/ttyS0 port ''0x0200'' irq ''5'' autoconfig

If stylus problems persist, try upgrading to the latest linuxwacom package: [http://www.cs.cornell.edu/~saikat/linuxwacom-0.6.8-5.i386.rpm linuxwacom-0.6.8-5.i386.rpm]

{{NOTE|
* When the stylus goes out of range from the screen, the mouse cursor warps to the top-left corner. When the mouse comes back in range, the cursor should warp back to the right spot. This can be particularly annoying if the temporary jump causes focus and menus to change. This is a known bug in the wacom X driver.}}

=== Audio ===

Audio works out of the box on X41 Tablets with the ALSA intel8x0 driver. '''Note:''' Sometimes the mixer settings are muted on startup resulting in no sound. This can be fixed using any alsa mixer such as aumix, amixer, gnome-volume-control etc. If the mixers are being repeatedly muted, then first unmute them and set them to desirable levels. As root, execute the command {{cmdroot|/usr/sbin/alsactl store}}. Finally, add the following line to {{path|/etc/rc.d/rc.local}}.

/usr/sbin/alsactl restore

=== ACPI ===

ACPI events are supported out of the box with [[ibm-acpi]]. Install it by executing:

:{{cmduser|wget http://www.cs.cornell.edu/~saikat/ibm-acpi-0.11-2.fc4.i386.rpm}}
:{{cmdroot|rpm -Uvh ibm-acpi-0.11-2.fc4.i386.rpm}}

Change the button bindings in {{path|/etc/acpi/events}}. If you do not plan to use Suspend to Disk (below), set the power button to halt the system instead of hibernating by changing {{path|/etc/acpi/events/hibernate}}.

=== Suspend ===

==== Suspend to Disk (Hibernation) ====

Software suspend works using [[Software Suspend 2]]. Follow the installation directions at http://mhensler.de/swsusp/. To automatically fix the stylus lock-up after resuming, add the following line to {{path|/etc/hibernate/hibernate.conf}}

OnResume 96 setserial /dev/ttyS0 port 0x0200 irq 5 autoconfig

If the stylus still locks up, see the Stylus section for the latest driver. ACPI power events are not delivered if AC status changes during hibernation. To tune the laptop after resume, add the following line to {{path|/etc/hibernate/hibernate.conf}}
OnResume 20 /etc/acpi/actions/battery.sh

==== Suspend to Memory (ACPI Sleep) ====

ACPI suspend to memory does not work with the 2.6.12 and earlier kernels because the X41 Tablet uses SATA access to the harddisk and the kernel SATA driver is not power-aware.
See [[Problems with SATA and Linux]] for further discussion and solutions.
(should be fixed in 2.6.15)

In any case, in {{path|/etc/grub.conf}} append the kernel parameter: {{bootparm|acpi_sleep|s3_bios}}

This is required to fix the problem where the screen doesn't turn back on after resuming from ACPI sleep.

{{WARN|Do ''NOT'' attempt ACPI sleep on the X41 Tablet running kernel 2.6.12 or earlier since the harddisk SATA driver doesn't resume properly. This can result in '''FILESYSTEM CORRUPTION'''.}}

=== Extra Buttons ===

Extra buttons work out-of-the-box. The package <tt>tpb</tt> provides some on-screen feedback for the volume, brightness and thinklight buttons. {{cmdroot|setkeycodes}} can be used to map the tablet buttons ([[Tablet Hardware Buttons|details]]).

To map the Tablet Up and Down buttons to Page Up and Page Down keys, and the Tablet Enter and Esc buttons to their respective counterparts, add the following to {{path|/etc/rc.d/rc.local}}.
setkeycodes 6e 109 6d 104 69 28 6b 1

=== Wireless Card ===

The 802.11b/g card is supported by the <tt>ipw2200</tt> driver. The easiest way to install it is to get the package from ATRpms. (Warning: please be warned about ATrpms: http://fedoraproject.org/wiki/JohnMahowald/ATrpmsWarning

:{{cmduser|wget http://dl.atrpms.net/all/atrpms-kickstart-28-1.rhfc4.at.i386.rpm}}
:{{cmdroot|rpm -Uvh atrpms-kickstart-28-1.rhfc4.at.i386.rpm}}
:{{cmdroot|apt-get update && apt-get dist-upgrade}}
:{{cmdroot|apt-get install ipw2200-firmware}}

Some (newer) X41 Tablets use the Atheros chipset. Download and build the drivers from http://sourceforge.net/projects/madwifi/

=== Bluetooth ===

Some (newer) X41 Tablets support bluetooth. My 18695CU, unfortunately, does not. So I have no clue.

== Software ==

=== Network Manager ===

[http://people.redhat.com/dcbw/NetworkManager/ NetworkManager] is a rather useful utility included in Fedora Core 4 that provides windows-like ease of configuring wireless and wired network as and when they are available. Give it a try by enabling it in the initscripts by running {{cmdroot|chkconfig NetworkManager on && /etc/init.d/NetworkManager restart}} as root and running {{cmduser|NetworkManagerInfo}} from a X session. The first command needs to be executed only once, while the second should be executed after every login. This can be automated by adding it to the list of startup programs in {{path|Desktop > Preferences > More Preferences > Sessions > Startup Programs}}.

=== Sun's Java ===

[http://java.sun.com Sun's Java VM] is needed by the Jarnal application below. Due to licensing issues, the JVM cannot be packaged but needs to be build by the end user. [http://www.jpackage.org JPackage] provides a build environment as follows:

* Download the build: {{cmduser|wget http://mirrors.dotsrc.org/jpackage/1.6/generic/non-free/SRPMS/java-1.5.0-sun-1.5.0.05-1jpp.nosrc.rpm}}
* Create the build environment: {{cmdroot|rpm -Uvh java-1.5.0-sun-1.5.0.05-1jpp.nosrc.rpm}}
* Download the JVM from [http://javashoplm.sun.com/ECom/docs/Welcome.jsp?StoreId=22&PartDetailId=jdk-1.5.0_05-oth-JPR&SiteId=JSC&TransactionId=noreg Sun's Java page] and download <tt>jdk-1_5_0_05-linux-i586.bin</tt> to {{path|/usr/src/redhat/SOURCES}}
* Build the RPMs: {{cmdroot|rpmbuild -ba /usr/src/redhat/SPECS/java-1.5.0-sun.spec}}
* Install the JVM: {{cmdroot|rpm -Uvh /usr/src/redhat/RPMS/i586/java-1.5.0-sun-1.5.0.05-1jpp.i586.rpm}}

== Installation ==

The {{X41T}} requires a dock to use an optical drive. The BIOS can, however, boot from USB or the network.

=== Preparation ===

The {{X41T}} comes installed with Windows XP Tablet edition. Before installing {{Fedora}}, the harddrive needs to be repartitioned and certain parameters need to be written down for later use.

# Use Powerquest Partition Magic, QTParted or some software that can partition a basic disk with NTFS partitions to create room for Fedora Core 4.
# Under windows, note the serial port and the irq used by the Wacom stylus device. This information is listed under {{path|Control Panel > System > Hardware > Device Manager > HID > Wacom Stylus > Resources}}. On the 18695CU model, the port is 0200-0207 and irq is 5.
# Note the MAC address of the ethernet card and the wireless card. These are on a stickers under the laptop labled LAN MAC Address and 802.11b/g MAC Address.

=== USB Boot Preparation ===

From the Fedora Core 4 DVD, write the bootimage to a USB device.

dd if=images/diskboot.img of=/dev/sdb

where {{path|/dev/sdb}} is the USB device. '''Note:''' The destination is {{path|/dev/sdb}} and not {{path|/dev/sdb1}}. Also perhaps due to a BIOS problem or image problem, USB booting may not always work.

=== PXE Boot Preparation ===

PXE boot requires the X41 Tablet to be connected to a wired ethernet network that is configured for DHCP and TFTP. This can be accomplished by connecting the tablet to another host over a ethernet corssover cable.

Configure the DHCP server to hand out boot instructions. In the {{path|/etc/dhcpd.conf}} file, include:

host pxeclient {
hardware ethernet ''00:0a:e4:35:a9:12''; # X41 Tablet LAN MAC Adress noted above
filename "/pxelinux.0";
fixed-address ''192.168.1.60''; # IP Address for X41 Tablet
next-server ''192.168.1.1''; # IP Address of TFTP server
}

'''Note:''' Replace the ''italicized'' fields above with appropriate values for your hardware. A sample dhcpd.conf file can be found here.

Configure the TFTP server. If the TFPT server uses xinetd, you may need to enable it in {{path|/etc/xinetd.d/tftp}} by setting <code>disable = no</code>. Also note root of the server. This is usually {{path|/tftpboot}}. Copy the pxelinux files present on the FC4 disk in {{path|images/pxelinux/}} to the TFTP root. You will need two additional files [http://www.cs.cornell.edu/~saikat/pxelinux.0 {{path|pxelinux.0}}] and {{path|pxelinux.cfg/default}}.

:{{cmduser|find /tftpboot}}
:{{cmdresult|/tftpboot}}
:{{cmdresult|/tftpboot/pxelinux.0}}
:{{cmdresult|/tftpboot/initrd.img}}
:{{cmdresult|/tftpboot/vmlinuz}}
:{{cmdresult|/tftpboot/pxelinux.cfg}}
:{{cmdresult|/tftpboot/pxelinux.cfg/default}}

Contents of {{path|/tftpboot/pxelinux.cfg/default}}:
DEFAULT vm
SERIAL 0 9600
label vm
kernel vmlinuz
append initrd=initrd.img ramdisk_size=9372 root=/dev/rd/0

=== Installing ===

Restart the X41 Tablet. If you are using a USB key, insert it before switching on the tablet. Press {{key|F12}} during startup to display the temporary boot device screen. Select either USB HDD or Netowkr Boot based on your medium of choice. This should bring up the Fedora Core installer. Once the installer has started up, Fedora Core can be installed over the web, ftp, nfs, USB disk etc. The rest of the installation is straight forward and described in detail here.

{{NOTE|There may be some screen corruption or shimmering effects in the graphical installer. This can be fixed after installation is complete as explained in the X Server Configuration below.}}

== Configuration ==

=== X Server ===

The X41 Tablet, uses an Intel integrated 915 video device. This is supported by the '''i810''' driver and can be selected from the graphical xserver screen by selecting the ''Intel 915'' option. '''Note:''' The <tt>i810</tt> driver on <tt>xorg-6.8.2</tt> and earlier '''DO NOT''' support the card. Use the <tt>vesa (generic)</tt> option for such servers. The LCD screen is a <tt>1024x768</tt> display. The stylus requires the <tt>linuxwacom</tt> package. This should automatically be installed as part of FC4. If you update FC4 with the latest rpms the i810 driver will work. You can use <tt>system-config-display</tt> to change the driver, but do it before adding configuration for stylus since it will drop the stylus related settings. For some additional information about rotating the screen and installing FC4 see http://www.dklevine.com/general/software/tc1000/x41f4.html

{{NOTE|
# The first time <tt>vesa (generic)</tt> is selected, there may appear to be some screen corruption or shimmering effects. It should go away after a reboot.
# The stylus may not work as a mouse immidiately. See the Stylus section below.
# Screen rotation on-the-fly currently does ''not'' work. It may be possible to pass a kernel parameter at boot time to rotate the framebuffer into a portrait orientation, but this has not been confirmed.

=== Stylus ===

The stylus is not recognized in Fedora Core at startup. Connect {{path|/dev/ttyS0}} to the stylus by including the following line in {{path|/etc/rc.d/rc.local}}.

setserial /dev/ttyS0 port ''0x0200'' irq ''5'' autoconfig

If stylus problems persist, try upgrading to the latest linuxwacom package: [http://www.cs.cornell.edu/~saikat/linuxwacom-0.6.8-5.i386.rpm linuxwacom-0.6.8-5.i386.rpm]

{{NOTE|
* When the stylus goes out of range from the screen, the mouse cursor warps to the top-left corner. When the mouse comes back in range, the cursor should warp back to the right spot. This can be particularly annoying if the temporary jump causes focus and menus to change. This is a known bug in the wacom X driver.}}

=== Audio ===

Audio works out of the box on X41 Tablets with the ALSA intel8x0 driver. '''Note:''' Sometimes the mixer settings are muted on startup resulting in no sound. This can be fixed using any alsa mixer such as aumix, amixer, gnome-volume-control etc. If the mixers are being repeatedly muted, then first unmute them and set them to desirable levels. As root, execute the command {{cmdroot|/usr/sbin/alsactl store}}. Finally, add the following line to {{path|/etc/rc.d/rc.local}}.

/usr/sbin/alsactl restore

=== ACPI ===

ACPI events are supported out of the box with [[ibm-acpi]]. Install it by executing:

:{{cmduser|wget http://www.cs.cornell.edu/~saikat/ibm-acpi-0.11-2.fc4.i386.rpm}}
:{{cmdroot|rpm -Uvh ibm-acpi-0.11-2.fc4.i386.rpm}}

Change the button bindings in {{path|/etc/acpi/events}}. If you do not plan to use Suspend to Disk (below), set the power button to halt the system instead of hibernating by changing {{path|/etc/acpi/events/hibernate}}.

=== Suspend ===

==== Suspend to Disk (Hibernation) ====

Software suspend works using [[Software Suspend 2]]. Follow the installation directions at http://mhensler.de/swsusp/. To automatically fix the stylus lock-up after resuming, add the following line to {{path|/etc/hibernate/hibernate.conf}}

OnResume 96 setserial /dev/ttyS0 port 0x0200 irq 5 autoconfig

If the stylus still locks up, see the Stylus section for the latest driver. ACPI power events are not delivered if AC status changes during hibernation. To tune the laptop after resume, add the following line to {{path|/etc/hibernate/hibernate.conf}}
OnResume 20 /etc/acpi/actions/battery.sh

==== Suspend to Memory (ACPI Sleep) ====

ACPI suspend to memory does not work with the 2.6.12 and earlier kernels because the X41 Tablet uses SATA access to the harddisk and the kernel SATA driver is not power-aware.
See [[Problems with SATA and Linux]] for further discussion and solutions.
(should be fixed in 2.6.15)

In any case, in {{path|/etc/grub.conf}} append the kernel parameter: {{bootparm|acpi_sleep|s3_bios}}

This is required to fix the problem where the screen doesn't turn back on after resuming from ACPI sleep.

{{WARN|Do ''NOT'' attempt ACPI sleep on the X41 Tablet running kernel 2.6.12 or earlier since the harddisk SATA driver doesn't resume properly. This can result in '''FILESYSTEM CORRUPTION'''.}}

=== Extra Buttons ===

Extra buttons work out-of-the-box. The package <tt>tpb</tt> provides some on-screen feedback for the volume, brightness and thinklight buttons. {{cmdroot|setkeycodes}} can be used to map the tablet buttons ([[Tablet Hardware Buttons|details]]).

To map the Tablet Up and Down buttons to Page Up and Page Down keys, and the Tablet Enter and Esc buttons to their respective counterparts, add the following to {{path|/etc/rc.d/rc.local}}.
setkeycodes 6e 109 6d 104 69 28 6b 1

=== Wireless Card ===

The 802.11b/g card is supported by the <tt>ipw2200</tt> driver. The easiest way to install it is to get the package from ATRpms. (Warning: please be warned about ATrpms: http://fedoraproject.org/wiki/JohnMahowald/ATrpmsWarning

:{{cmduser|wget http://dl.atrpms.net/all/atrpms-kickstart-28-1.rhfc4.at.i386.rpm}}
:{{cmdroot|rpm -Uvh atrpms-kickstart-28-1.rhfc4.at.i386.rpm}}
:{{cmdroot|apt-get update && apt-get dist-upgrade}}
:{{cmdroot|apt-get install ipw2200-firmware}}

Some (newer) X41 Tablets use the Atheros chipset. Download and build the drivers from http://sourceforge.net/projects/madwifi/

=== Bluetooth ===

Some (newer) X41 Tablets support bluetooth. My 18695CU, unfortunately, does not. So I have no clue.

== Software ==

=== Network Manager ===

[http://people.redhat.com/dcbw/NetworkManager/ NetworkManager] is a rather useful utility included in Fedora Core 4 that provides windows-like ease of configuring wireless and wired network as and when they are available. Give it a try by enabling it in the initscripts by running {{cmdroot|chkconfig NetworkManager on && /etc/init.d/NetworkManager restart}} as root and running {{cmduser|NetworkManagerInfo}} from a X session. The first command needs to be executed only once, while the second should be executed after every login. This can be automated by adding it to the list of startup programs in {{path|Desktop > Preferences > More Preferences > Sessions > Startup Programs}}.

=== Sun's Java ===

[http://java.sun.com Sun's Java VM] is needed by the Jarnal application below. Due to licensing issues, the JVM cannot be packaged but needs to be build by the end user. [http://www.jpackage.org JPackage] provides a build environment as follows:

* Download the build: {{cmduser|wget http://mirrors.dotsrc.org/jpackage/1.6/generic/non-free/SRPMS/java-1.5.0-sun-1.5.0.05-1jpp.nosrc.rpm}}
* Create the build environment: {{cmdroot|rpm -Uvh java-1.5.0-sun-1.5.0.05-1jpp.nosrc.rpm}}
* Download the JVM from [http://javashoplm.sun.com/ECom/docs/Welcome.jsp?StoreId=22&PartDetailId=jdk-1.5.0_05-oth-JPR&SiteId=JSC&TransactionId=noreg Sun's Java page] and download <tt>jdk-1_5_0_05-linux-i586.bin</tt> to {{path|/usr/src/redhat/SOURCES}}
* Build the RPMs: {{cmdroot|rpmbuild -ba /usr/src/redhat/SPECS/java-1.5.0-sun.spec}}
* Install the JVM: {{cmdroot|rpm -Uvh /usr/src/redhat/RPMS/i586/java-1.5.0-sun-1.5.0.05-1jpp.i586.rpm}}
* Install the fonts: {{cmdroot|rpm -Uvh /usr/src/redhat/RPMS/i586/java-1.5.0-sun-fonts-1.5.0.05-1jpp.i586.rpm}}

Note: This is tailored for the latest JVM as of writing this article. Substitute the latest version numbers if this doesn't work.

=== Jarnal ===

[http://www.dklevine.com/general/software/tc1000/jarnal.htm Jarnal] is a Notetaking application, much like Microsoft Journal for windows. It requires Sun's Java VM above.

* Download the RPM: {{cmduser|wget http://www.cs.cornell.edu/~saikat/jarnal-6.60-1sg.noarch.rpm}}
* Install it: {{cmdroot|rpm -Uvh jarnal-6.60-1sg.noarch.rpm}}

It should create a menu entry {{path|Notes}} under {{path|Applications > Graphics}}.

How to enable integrated fingerprint reader with BioAPI

2005-12-17T19:18:59Z

Ychao: /* Troubleshooting and Hints */

{| width="100%"
|style="vertical-align:top;padding-right:20px;width:10px;white-space:nowrap;" | __TOC__
|style="vertical-align:top" |
This page describes the process of getting the fingerprint reader to work. It is based on experiences in {{Ubuntu}} on a T43. The same works on {{Fedora}} 4, SuSE 10, and {{Gentoo}}.
|}

==Basic driver installation==
===Getting required libs and tools===
====Installing the bioapi framework====
=====Binary packages=====
*If you're using {{Debian}} Sid (the unstable branch) you can try the packages from Michael R. Crusoe's site, either [http://www.qrivy.net/~michael/temp/ version 1.2.3] (recommended) or [http://www.qrivy.net/~michael/debs/unstable/ older versions] which might not work with the steps in this howto.
*This seems to work for Ubuntu breezy/dapper too, so saver yourself some trouble and grab it.
=====Gentoo=====
You can either Grab the ebuild from http://www.qrivy.net/~michael/blua/bioapi/bioapi-1.2.2.ebuild.tar.bz2, or use the source-install procedure below.
=====Installing from source=====
*Get the bioapi source:
:{{cmduser|wget http://www.qrivy.net/~michael/blua/bioapi/bioapi-1.2.2.tar.bz2}}
*I could not compile bioapi with the graphical Qt tools. To do it manually, do the following:
:{{cmduser|tar xjf bioapi-1.2.2.tar.bz2}}
:{{cmduser|cd bioapi-1.2.2}}
:{{cmduser|1=./configure --with-Qt-dir=no}}
:{{cmduser|make}}
:and then as root
:{{cmdroot|make install}}
:If make install fails, be sure you're root and then:
:{{cmdroot|1=export LD_LIBRARY_PATH=/usr/local/lib}}
:{{cmdroot|make install}}
:and if you want to compile pam_bioapi for auth later
:{{cmdroot|cp include/bioapi_util.h include/installdefs.h imports/cdsa/v2_0/inc/cssmtype.h /usr/include}}
:Be aware that checkinstall will not work!
:(I got through configure with Qt, but got a cryptic build error. It all worked fine with Qt disabled as above)
:buzz: This is due to a wrong qt include path, set it manually in configure and everything should work.

====Installing the driver====
*Download {{path|TFMESS_BSP_LIN_1.0beta2.zip}} from http://www.qrivy.net/~michael/blua/upek-bsp.html and unzip it into a seperate folder, as it will not create one.
*Change to that folder and do as root:
:{{cmdroot|sh install.sh}}
:If that fails, it may be that make install failed up above -- try setting LD_LIBRARY_PATH, do the make install again, and come back here and try this again
*If you want to use PAM-aware applications like xscreensaver that are NOT running with root permissions (as opposed to login, gdm or other authentication mechanisms), do the following as root (this doesn't seem necessary on SuSE 10):
:{{cmdroot|chmod 777 -R /usr/local/var/bioapi/}}
:Actually this depends on where you installed, if you did as suggested, it should work. Otherwise you probably know what you're doing anyways. :)
:{{cmdroot|touch /var/log/BSP.log && chmod 666 /var/log/BSP.log}}
:{{cmdroot|chmod -R a+X /proc/bus/usb}}
:{{cmdroot|chmod 666 /proc/bus/usb/`/sbin/lsusb <nowiki>|</nowiki> sed -ne "/0483:2016/s/Bus\ $.*$\ Device\ $.*$:\ .*/\1\/\2/p"`}}
:It might be nessecary to put the above line into a startup script somewhere.

===Testing the driver===
Go to the folder where you extracted {{path|TFMESS_BSP_LIN_1.0beta2.zip}} and do:
:{{cmdroot|cd NonGUI_Sample}}
:{{cmdroot|chmod +x Sample}}
:{{cmdroot|./Sample}}
:Note that Sample may only run as root
:You can try to "e"nroll (to record a fingerprint for an account) and then "v"erify (to test a fingerprint against the one it expects for an account)
:You'll save a step later if you use your own login username as the username to enroll here

==Login via pam_bioapi==

The following explains how to add fingerprint authentiation to programs that use the PAM (Pluggable Authentication Modules) framework, such as the Gnome's GDM and KDE's KDM and screensaver.

===Getting required libs & tools===
====Installing pam_bioapi====
*Prerequisites
:On SuSE 10, I needed to install the pam-devel RPM
*Get and compile the pam_bioapi module.
:{{cmduser|wget http://www.qrivy.net/~michael/blua/pam_bioapi/pam_bioapi-0.2.1.tar.bz2}}
:{{cmduser|tar xjf pam_bioapi-0.2.1.tar.bz2}}
:{{cmduser|cd pam_bioapi-0.2.1}}
:{{cmduser|wget http://badcode.de/downloads/fingerprint.patch}}
:{{cmduser|patch -p0 < fingerprint.patch}}
:If you want to, review the patch. In general you should review all code you download and compile, if possible. The patch comes from [http://linuxbiometrics.com/modules/newbb/viewtopic.php?viewmode=flat&topic_id=80&forum=1 this thread].
:{{cmduser|./configure && make}}
{{NOTE|If encountering 'rpl_malloc' symbol, remove the related term in the makefile. (FC3)}}
:and as root
:{{cmdroot| make install}}
:{{cmdroot| cp /usr/local/lib/security/* /lib/security/}}
*Use the sample tool from the fingerprint reader to create {{path|<username>.bir}} (<tt><username></tt> '''must''' be the username you want to login with. gdm will probably break for any login name that has no .bir file).
*As root do:
:{{cmdroot|SERIAL<nowiki>=`BioAPITest | sed -ne "/Fingerprint/{n;n;s/^.*: $.\{9\}$$.\{4\}$$.\{4\}$$.\{4\}$$.*$/\1-\2-\3-\4-\5/gp}"` </nowiki>}}
:{{cmdroot|echo $SERIAL}} should print something like {{cmdresult|<nowiki>{5550454b-2054-464d-2f45-535320425350}</nowiki>}} now.
:If it does, do:
:{{cmdroot|mkdir -p /etc/bioapi/pam/$SERIAL}}
:{{cmdroot|cp <username>.bir /etc/bioapi/pam/$SERIAL}}

===Configuring pam===
The following part is distribution specific. On {{Ubuntu}} or SuSE you can modify {{path|/etc/pam.d/common-auth}} (on {{Gentoo}} and {{Fedora}} it is {{path|/etc/pam.d/system-auth}}) to look like this:

#
# /etc/pam.d/common-auth - authentication settings common to all services
#
# This file is included from other service-specific PAM config files,
# and should contain a list of the authentication modules that define
# the central authentication scheme for use on the system
# (e.g., /etc/shadow, LDAP, Kerberos, etc.). The default is to use the
# traditional Unix authentication mechanisms.
#
auth sufficient pam_bioapi.so {5550454b-2054-464d-2f45-535320425350} /etc/bioapi/pam/
password sufficient pam_bioapi.so {5550454b-2054-464d-2f45-535320425350} /etc/bioapi/pam/
auth required pam_unix.so nullok_secure

----
{{path|/etc/pam.d/system-auth}} for '''Gentoo'''-Users:

auth sufficient pam_bioapi.so {5550454b-2054-464d-2f45-535320425350} /etc/bioapi/pam/
password sufficient pam_bioapi.so {5550454b-2054-464d-2f45-535320425350} /etc/bioapi/pam/
auth required pam_unix.so nullok_secure
auth required pam_env.so

password sufficient pam_unix.so nullok md5 shadow use_authtok
password required pam_deny.so
session required pam_limits.so
session required pam_unix.so
----

With this modification pam immediately starts to use the fingerprint reader to do local authorization (e.g. sudo/gdm use the fingerprint reader).

''Note:'' With a system-auth like above, '''Gentoo''' will give you 'account expired' errors.
CREATE {{path|/etc/pam.d/common-auth}} like so.

account required pam_unix.so
auth sufficient pam_bioapi.so {5550454b-2054-464d-2f45-535320425350} /etc/bioapi/pam/
password sufficient pam_bioapi.so {5550454b-2054-464d-2f45-535320425350} /etc/bioapi/pam/
auth required pam_unix.so nullok_secure
session required pam_limits.so
session required pam_uni

Note that if su/sudo expects to receive the root password (SuSE 10), you need to have fingerprint settings for root (that is, copy in a root.bir as well as a your-username.bir). Otherwise, they get a segmentation fault. Which is a little unfortunate, given that you need to su or sudo to change your settings...

For some applications (kdm, SuSE 10 KDE screen saver), you'll need to enter an empty password (or select the correct user and then enter an empty password) in order to get the fingerprint prompt. kdm didn't give any visual indication it was going to the fingerprint reader, other than the cursor stopped blinking, but I swiped, and it let me in.

Note that sshd may pick up the fingerprint settings from {{path|/etc/pam.d/common-auth}}. I didn't want that, so I removed the "auth include common-auth" line from {{path|/etc/pam.d/sshd}} and replaced it with the lines that were originally in my {{path|/etc/pam.d/common-auth}}. That way most local services use the fingerprint reader, but sshd does not.

{{NOTE|This was discovered through trial and success, if it is plain wrong, wikorrect it, please.}}

On {{Fedora}}, you may need to add {{path|/usr/local/lib}} to your LD_LIBRARY path so that the libraries referenced from <tt>pam_bioapi.so</tt> get picked up properly. Also the original 'session' terms in {{path|/etc/pam.d/system-auth}} need to be kept.

On {{Fedora}}4 or {{Aurox}}11, You may need to add {{path|/usr/local/lib}} to ldconfig configuration.
:{{cmdroot|echo '/usr/local/lib' > /etc/ld.so.conf.d/bioapi.conf}}
:{{cmdroot|ldconfig}}
If You see bioapi libs
:{{cmdroot|ldconfig -p | grep bioapi}}
then it should works.

Now gdm should pop up an (ugly) image to swipe your finger and... magic - you can login without a password.

If You use kdm, there is no pop up.

==Make xscreensaver use the scanner==
*Get the needed xscreensaver sources:
:{{cmduser|wget http://www.jwz.org/xscreensaver/xscreensaver-4.23.tar.gz}}
:{{cmduser|tar xzf xscreensaver-4.23.tar.gz}}
:{{cmduser|cd xscreensaver-4.23}}
:{{cmduser|wget http://nax.hn.org/pub/bioapi/xscreensaver-4.22_alternativeAuth.diff}}
*After reviewing the patch (it's small and straightforward), do
:{{cmduser|patch -p1 < xscreensaver-4.22_alternativeAuth.diff}} The patch prevents xscreensaver from opening an authentification window and dispatches the authentification request to another program, in our case <tt>pam</tt> and <tt>pam_bioapi</tt>. It should apply with some offset, don't mind that. If it says something about rejected though, then there's a problem.
*Compile with
:{{cmduser|./configure --with-pam && make}} 
*If you recieve an error like "undefined reference to `XmuPrintDefaultErrorMessage'" then install the libxmu-dev package and run the previous line again
*and then install as root with
:{{cmduser|su -c make install}} .
*Make sure that the newly compiled xscreensaver is used:
:{{cmduser|which xscreensaver}} should return
:{{cmdresult|/usr/local/bin/xscreensaver}} .
:*In case it doesn't, try
::{{cmduser|1=export PATH=/usr/local/bin:$PATH}} and retry.
*Kill the running instance of xscreensaver:
:{{cmduser|xscreensaver-command -exit}}
*Make sure you have the following line in your {{path|~/.xscreensaver}}:
alternativeAuth: True
*Now edit {{path|/etc/pam.d/xscreensaver}} to include the following line (If you're on {{Ubuntu}} Breezy and you already changed {{path|/etc/pam.d/common-auth}} you should not need to do this.):
auth sufficient pam_bioapi.so {5550454b-2054-464d-2f45-535320425350} /etc/bioapi1.10/pam/
*Start the new xscreensaver
:{{cmduser|xscreensaver}} There should be a splash screen with version 4.23.
*Now try:
:{{cmduser|xscreensaver-command -lock}}

If you have questions or problems with this procedure, ask: t43fingerprint (at) badcode.de .

===Package for Debian sid===

If you're running {{Debian}} sid (the unstable branch) you can also try the patched .deb-package (built from current Debian sources fetched with {{cmd|apt-get source|}}) from [http://linux.spiney.org/debian_gnu_linux_on_an_ibm_thinkpad_t43p_fingerprint_reader this page], which also has Debian-specific instructions on how to setup the fingerprint reader. Use it on your own risk.

==Troubleshooting and Hints==
# After installing the driver, don't forget to reboot!
## This might not be necessary. it worked here without having to reboot.
# To see if the fingerprint device is know on the USB bus do:
:{{cmdroot|/sbin/lsusb}}
:as root and you should see a line like:
:{{cmdresult|Bus 003 Device 004: ID 0483:2016 SGS Thomson Microelectronics}}
:The bus and device number can be different. This should work without the driver installed. If the device does not show up, you have a hardware problem/quirk, Rebooting might fix this.
# For some installation, after installing the driver as in section [[#Installing the driver|Installing the driver]] and makingÂ´sure the device is recognized, try to test it by going to {{path|NonGUI_Sample}} directory and run {{cmdroot|./Sample}}, one get segmentation fault. In this case, try getting the Beta1 instead of Beta2 of the driver and installing it
# There was some confusion about the /etc/bioapi1.10/pam{5550454b-2054-464d-2f45-535320425350} path, this has been fixed in the howto, if you have problems, check the section again, the path needs to have the '-' in them
# When something goes wrong look at the tail of {{path|/var/log/auth.log}}. (on {{Fedora}} it is {{path|/var/log/secure}}) Specifically if you see an entry saying something like
pam_bioapi[10480]: Unable to load BioAPI BSP with UUID of {5550454b-2054-464d-2f45-535320425350}, BioAPI error <nowiki>#</nowiki>194d.
Check whether your {{path|/proc/bus/usb}} directory permissions are set up as in the
section [[#Installing the driver|Installing the driver]].
# To get the xscreensaver compiled you might need a bunch of header files, in my case I need the following:
#*python-gtk2-dev
#*libgstreamer0.8-dev
#*xlibs-dev
# Sometimes {{path|$HOME/.xscreensaver}} got overwritten, try changing it to read-only.
# If after suspending to RAM and resume, lsusb no longer have "SGS Thomson Microelectronics" entry, try adding a line
:{{cmdroot|/etc/init.d/hotplug restart}}
to your {{path|/etc/acpi/resume.sh}} file
#If after resume lsusb shows the device but xscreensaver does not ask for fingerprint for login, you might want to check the permission of the usb bus in the appropriate {{path|/proc/bus/usb/}} entry. If necessesary you might need to add a line to {{path|/etc/acpi/resume.sh}} as in section [[#Installing the driver|Installing the driver]] to set the permission right.
-----
If it still doesn't work, ask me for help (and make sure all usefull stuff makes it back into this wiki :)
to get a starting point as to where your problem is please include the output of:

:{{cmduser|lsusb}}

:{{cmduser|ldconfig -p | grep bioapi}}

This page describes the process of getting the fingerprint reader to work. It is based on experiences in {{Ubuntu}} on a T43. The same works on {{Fedora}} 4.
|}

==Basic driver installation==
===Getting required libs and tools===
====Installing the bioapi source====
*Get the bioapi source:
:{{cmduser|wget http://www.qrivy.net/~michael/blua/bioapi/bioapi-1.2.2.tar.bz2}}
*I could not compile bioapi with the graphical Qt tools. To do it manually, do the following:
:{{cmduser|tar xjf bioapi-1.2.2.tar.bz2}}
:{{cmduser|cd bioapi-1.2.2}}
:{{cmduser|1=./configure --with-Qt-dir=no}}
:{{cmduser|make}}
:and then as root
:{{cmdroot|make install}}
:and if you want to compile pam_bioapi for auth later
:{{cmdroot|cp include/bioapi_util.h include/installdefs.h imports/cdsa/v2_0/inc/cssmtype.h /usr/include}}
:Be aware that checkinstall will not work!

====Installing the driver====
*Download {{path|TFMESS_BSP_LIN_1.0beta2.zip}} from http://www.qrivy.net/~michael/blua/upek-bsp.html and unzip it into a seperate folder, as it will not create one.
*Change to that folder and do as root:
:{{cmdroot|sh install.sh}}
*If you want to use PAM-aware applications like xscreensaver that are NOT running with root permissions (as opposed to login, gdm or other authentication mechanisms), do the following as root:
:{{cmdroot|chmod 777 -R /usr/local/var/bioapi/}}
:Actually this depends on where you installed, if you did as suggested, it should work. Otherwise you probably know what you're doing anyways. :)
:{{cmdroot|touch /var/log/BSP.log && chmod 666 /var/log/BSP.log}}
:{{cmdroot|chmod -R a+X /proc/bus/usb}}
:{{cmdroot|chmod 666 /proc/bus/usb/`/sbin/lsusb <nowiki>|</nowiki> sed -ne "/0483:2016/s/Bus\ $.*$\ Device\ $.*$:\ .*/\1\/\2/p"`}}
:It might be nessecary to put the above line into a startup script somewhere.

===Testing the driver===
Go to the folder where you extracted {{path|TFMESS_BSP_LIN_1.0beta2.zip}} and do:
:{{cmdroot|cd NonGUI_Sample}}
:{{cmdroot|chmod +x Sample}}
:{{cmdroot|./Sample}}
If it doesn't work, ask for help at: t43fingerprint (at) badcode.de

==GDM Login via pam_bioapi==
===Getting required libs & tools===
====Installing pam_bioapi====
*Get and compile the pam_bioapi module.
:{{cmduser|wget http://www.qrivy.net/~michael/blua/pam_bioapi/pam_bioapi-0.2.1.tar.bz2}}
:{{cmduser|tar xjf pam_bioapi-0.2.1.tar.bz2}}
:{{cmduser|cd pam_bioapi-0.2.1}}
:{{cmduser|wget http://badcode.de/downloads/fingerprint.patch}}
:{{cmduser|patch -p0 < fingerprint.patch}}
:If you want to, review the patch. In general you should review all code you download and compile, if possible. The patch comes from [http://linuxbiometrics.com/modules/newbb/viewtopic.php?viewmode=flat&topic_id=80&forum=1 this thread].
:{{cmduser|./configure && make}}
{{NOTE|If encountering 'rpl_malloc' symbol, remove the related term in the makefile. (FC3)}}
:and as root
:{{cmdroot| make install}}
:{{cmdroot| cp /usr/local/lib/security/* /lib/security/}}
*Use the sample tool from the fingerprint reader to create {{path|<username>.bir}} (<tt><username></tt> '''must''' be the username you want to login with. gdm will probably break for any login name that has no .bir file).
*As root do:
:{{cmdroot|SERIAL<nowiki>=`BioAPITest | sed -ne "/Fingerprint/{n;n;s/^.*: $.\{9\}$$.\{4\}$$.\{4\}$$.\{4\}$$.*$/\1-\2-\3-\4-\5/gp}"` </nowiki>}}
:{{cmdroot|echo $SERIAL}} should print something like {{cmdresult|<nowiki>{5550454b-2054-464d-2f45-535320425350}</nowiki>}} now.
:If it does, do:
:{{cmdroot|mkdir -p /etc/bioapi1.10/pam/$SERIAL}}
:{{cmdroot|cp <username>.bir /etc/bioapi1.10/pam/$SERIAL}}

===Configuring pam===
The following part is distribution specific. On {{Ubuntu}} you can modify {{path|/etc/pam.d/common-auth}} (on {{Gentoo}} and {{Fedora}} it is {{path|/etc/pam.d/system-auth}}) to look like this:

#
# /etc/pam.d/common-auth - authentication settings common to all services
#
# This file is included from other service-specific PAM config files,
# and should contain a list of the authentication modules that define
# the central authentication scheme for use on the system
# (e.g., /etc/shadow, LDAP, Kerberos, etc.). The default is to use the
# traditional Unix authentication mechanisms.
#
auth sufficient pam_bioapi.so {5550454b-2054-464d-2f45-535320425350} /etc/bioapi1.10/pam/
password sufficient pam_bioapi.so {5550454b-2054-464d-2f45-535320425350} /etc/bioapi1.10/pam/
auth required pam_unix.so nullok_secure

With this modification pam immediatelly starts to use the fingerprint reader to do local authorization (e.g. sudo/gdm use the fingerprint reader).

{{NOTE|This was discovered through trial and success, if it is plain wrong, wikorrect it, please.}}

On {{Fedora}}, you may need to add {{path|/usr/local/lib}} to your LD_LIBRARY path so that the libraries referenced from <tt>pam_bioapi.so</tt> get picked up properly. Also the original 'session' terms in {{path|/etc/pam.d/system-auth}} need to be kept.

Now gdm should pop up an (ugly) image to swipe your finger and... magic - you can login without a password.

==Make xscreensaver use the scanner==
*Get the needed xscreensaver sources:
:{{cmduser|wget http://www.jwz.org/xscreensaver/xscreensaver-4.23.tar.gz}}
:{{cmduser|tar xzf xscreensaver-4.23.tar.gz}}
:{{cmduser|cd xscreensaver-4.23}}
:{{cmduser|wget http://nax.hn.org/pub/bioapi/xscreensaver-4.22_alternativeAuth.diff}}
*After reviewing the patch (it's small and straightforward), do
:{{cmduser|patch -p1 < xscreensaver-4.22_alternativeAuth.diff}} The patch prevents xscreensaver from opening an authentification window and dispatches the authentification request to another program, in our case <tt>pam</tt> and <tt>pam_bioapi</tt>. It should apply with some offset, don't mind that. If it says something about rejected though, then there's a problem.
*Compile with
:{{cmduser|./configure --with-pam && make}} and then install as root with
:{{cmduser|su -c make install}} .
*Make sure that the newly compiled xscreensaver is used:
:{{cmduser|which xscreensaver}} should return
:{{cmdresult|/usr/local/bin/xscreensaver}} .
:*In case it doesn't, try
::{{cmduser|1=export PATH=/usr/local/bin:$PATH}} and retry.
*Kill the running instance of xscreensaver:
:{{cmduser|xscreensaver-command -exit}}
*Make sure you have the following line in your {{path|~/.xscreensaver}}:
alternativeAuth: True
*Now edit {{path|/etc/pam.d/xscreensaver}} to include the following line (If you're on {{Ubuntu}} Breezy and you already changed {{path|/etc/pam.d/common-auth}} you should not need to do this.):
auth sufficient pam_bioapi.so {5550454b-2054-464d-2f45-535320425350} /etc/bioapi1.10/pam/

|}

==Basic driver installation==
===Getting required libs and tools===
====Installing the bioapi source====
*Get the bioapi source:
:{{cmduser|wget http://www.qrivy.net/~michael/blua/bioapi/bioapi-1.2.2.tar.bz2}}
*I could not compile bioapi with the graphical Qt tools. To do it manually, do the following:
:{{cmduser|tar xjf bioapi-1.2.2.tar.bz2}}
:{{cmduser|cd bioapi-1.2.2}}
:{{cmduser|1=./configure --with-Qt-dir=no}}
:{{cmduser|make}}
:and then as root
:{{cmdroot|make install}}
:and if you want to compile pam_bioapi for auth later
:{{cmdroot|cp include/bioapi_util.h include/installdefs.h imports/cdsa/v2_0/inc/cssmtype.h /usr/include}}
:Be aware that checkinstall will not work!

====Installing the driver====
*Download {{path|TFMESS_BSP_LIN_1.0beta2.zip}} from http://www.qrivy.net/~michael/blua/upek-bsp.html and unzip it into a seperate folder, as it will not create one.
*Change to that folder and do as root:
:{{cmdroot|sh install.sh}}
*If you want to use PAM-aware applications like xscreensaver that are NOT running with root permissions (as opposed to login, gdm or other authentication mechanisms), do the following as root:
:{{cmdroot|chmod 777 -R /usr/local/var/bioapi/}}
:Actually this depends on where you installed, if you did as suggested, it should work. Otherwise you probably know what you're doing anyways. :)
:{{cmdroot|touch /var/log/BSP.log && chmod 666 /var/log/BSP.log}}
:{{cmdroot|chmod -R a+X /proc/bus/usb}}
:{{cmdroot|chmod 666 /proc/bus/usb/`/sbin/lsusb <nowiki>|</nowiki> sed -ne "/0483:2016/s/Bus\ $.*$\ Device\ $.*$:\ .*/\1\/\2/p"`}}
:It might be nessecary to put the above line into a startup script somewhere.

===Testing the driver===
Go to the folder where you extracted {{path|TFMESS_BSP_LIN_1.0beta2.zip}} and do:
:{{cmdroot|cd NonGUI_Sample}}
:{{cmdroot|chmod +x Sample}}
:{{cmdroot|./Sample}}
If it doesn't work, ask for help at: t43fingerprint (at) badcode.de

==GDM Login via pam_bioapi==
===Getting required libs & tools===
====Installing pam_bioapi====
*Get and compile the pam_bioapi module.
:{{cmduser|wget http://www.qrivy.net/~michael/blua/pam_bioapi/pam_bioapi-0.2.1.tar.bz2}}
:{{cmduser|tar xjf pam_bioapi-0.2.1.tar.bz2}}
:{{cmduser|cd pam_bioapi-0.2.1}}
:{{cmduser|wget http://badcode.de/downloads/fingerprint.patch}}
:{{cmduser|patch -p0 < fingerprint.patch}}
:If you want to, review the patch. In general you should review all code you download and compile, if possible. The patch comes from [http://linuxbiometrics.com/modules/newbb/viewtopic.php?viewmode=flat&topic_id=80&forum=1 this thread].
:{{cmduser|./configure && make}}
{{NOTE|If encountering 'rpl_malloc' symbol, remove the related term in the makefile. (FC3)}}
:and as root
:{{cmdroot| make install}}
:{{cmdroot| cp /usr/local/lib/security/* /lib/security/}}
*Use the sample tool from the fingerprint reader to create {{path|<username>.bir}} (<tt><username></tt> '''must''' be the username you want to login with. gdm will probably break for any login name that has no .bir file).
*As root do:
:{{cmdroot|SERIAL<nowiki>=`BioAPITest | sed -ne "/Fingerprint/{n;n;s/^.*: $.\{9\}$$.\{4\}$$.\{4\}$$.\{4\}$$.*$/\1-\2-\3-\4-\5/gp}"` </nowiki>}}
:{{cmdroot|echo $SERIAL}} should print something like {{cmdresult|<nowiki>{5550454b-2054-464d-2f45-535320425350}</nowiki>}} now.
:If it does, do:
:{{cmdroot|mkdir -p /etc/bioapi1.10/pam/$SERIAL}}
:{{cmdroot|cp <username>.bir /etc/bioapi1.10/pam/$SERIAL}}

===Configuring pam===
The following part is distribution specific. On {{Ubuntu}} you can modify {{path|/etc/pam.d/common-auth}} (on {{Gentoo}} and {{Fedora}} it is {{path|/etc/pam.d/system-auth}}) to look like this:

#
# /etc/pam.d/common-auth - authentication settings common to all services
#
# This file is included from other service-specific PAM config files,
# and should contain a list of the authentication modules that define
# the central authentication scheme for use on the system
# (e.g., /etc/shadow, LDAP, Kerberos, etc.). The default is to use the
# traditional Unix authentication mechanisms.
#
auth sufficient pam_bioapi.so {5550454b-2054-464d-2f45-535320425350} /etc/bioapi1.10/pam/
password sufficient pam_bioapi.so {5550454b-2054-464d-2f45-535320425350} /etc/bioapi1.10/pam/
auth required pam_unix.so nullok_secure

With this modification pam immediatelly starts to use the fingerprint reader to do local authorization (e.g. sudo/gdm use the fingerprint reader).

{{NOTE|This was discovered through trial and success, if it is plain wrong, wikorrect it, please.}}

On {{Fedora}}, you may need to add {{path|/usr/local/lib}} to your LD_LIBRARY path so that the libraries referenced from <tt>pam_bioapi.so</tt> get picked up properly.

Now gdm should pop up an (ugly) image to swipe your finger and... magic - you can login without a password.

==Make xscreensaver use the scanner==
*Get the needed xscreensaver sources:
:{{cmduser|wget http://www.jwz.org/xscreensaver/xscreensaver-4.23.tar.gz}}
:{{cmduser|tar xzf xscreensaver-4.23.tar.gz}}
:{{cmduser|cd xscreensaver-4.23}}
:{{cmduser|wget http://nax.hn.org/pub/bioapi/xscreensaver-4.22_alternativeAuth.diff}}
*After reviewing the patch (it's small and straightforward), do
:{{cmduser|patch -p1 < xscreensaver-4.22_alternativeAuth.diff}} The patch prevents xscreensaver from opening an authentification window and dispatches the authentification request to another program, in our case <tt>pam</tt> and <tt>pam_bioapi</tt>. It should apply with some offset, don't mind that. If it says something about rejected though, then there's a problem.
*Compile with
:{{cmduser|./configure --with-pam && make}} and then install as root with
:{{cmduser|su -c make install}} .
*Make sure that the newly compiled xscreensaver is used:
:{{cmduser|which xscreensaver}} should return
:{{cmdresult|/usr/local/bin/xscreensaver}} .
:*In case it doesn't, try
::{{cmduser|1=export PATH=/usr/local/bin:$PATH}} and retry.
*Kill the running instance of xscreensaver:
:{{cmduser|xscreensaver-command -exit}}
*Make sure you have the following line in your {{path|~/.xscreensaver}}:
alternativeAuth: True
*Now edit {{path|/etc/pam.d/xscreensaver}} to include the following line (If you're on {{Ubuntu}} Breezy and you already changed {{path|/etc/pam.d/common-auth}} you should not need to do this.):
auth sufficient pam_bioapi.so {5550454b-2054-464d-2f45-535320425350} /etc/bioapi1.10/pam/
*Start the new xscreensaver
:{{cmduser|xscreensaver}} There should be a splash screen with version 4.23.
*Now try:
:{{cmduser|xscreensaver-command -lock}}

How to make ACPI work

2005-08-25T01:49:39Z

Ychao: /* Suspend to RAM (Sleep) */

==general==
===Kernel configuration===
First of all you'll have to enable ACPI support in your kernel (if your distro doesn't already have an ACPI enabled kernel).
To do this open your kernel config and enable ACPI Power Management:
:{{kernelconf||||Power management options|Power Management support|<*>|CONFIG_PM}}
:{{kernelconf||||Power management options|ACPI|<*>|CONFIG_ACPI_SLEEP}}

You'd most likely want to enable the following ACPI options:
:{{kernelconf|||Power management options|ACPI|Sleep States|<*>|CONFIG_ACPI_SLEEP}}
:{{kernelconf|||Power management options|ACPI|AC Adapter|<*>|CONFIG_ACPI_AC}}
:{{kernelconf|||Power management options|ACPI|Battery|<*>|CONFIG_ACPI_BATTERY}}
:{{kernelconf|||Power management options|ACPI|Fan|<*>|CONFIG_ACPI_FAN}}
:{{kernelconf|||Power management options|ACPI|Processor|<*>|CONFIG_ACPI_PROCESSOR}}
:{{kernelconf|||Power management options|ACPI|Thermal Zone|<*>|CONFIG_ACPI_THERMAL}}

If you prefer editing your {{path|.config}} file directly, you should set at least the following variables:
CONFIG_PM=y
CONFIG_ACPI_BOOT=y
CONFIG_ACPI_INTERPRETER=y
CONFIG_ACPI_SLEEP=y
CONFIG_ACPI_SLEEP_PROC_FS=y
CONFIG_ACPI_AC=y
CONFIG_ACPI_BATTERY=y
CONFIG_ACPI_BUTTON=y
CONFIG_ACPI_FAN=y
CONFIG_ACPI_PROCESSOR=y
CONFIG_ACPI_THERMAL=y
CONFIG_ACPI_BUS=y
CONFIG_ACPI_EC=y
CONFIG_ACPI_POWER=y
CONFIG_ACPI_PCI=y
CONFIG_ACPI_SYSTEM=y

Then recompile your kernel.

===IBM specific ACPI driver===
Unfortunately, special drivers for ACPI on ThinkPads were not included with kernels prior 2.6.10. So you'll have to compile one yourself or get it as precompiled module for your kernel.

You have the choice between [[thinkpad-acpi]] and [[ibm-acpi]], with the latter being the recommended one.

If you use a post-2.6.10 kernel and you want to use [[ibm-acpi]], it is recommended to look on its projects page for a possibly newer version.

{{HINT|In general it is a good idea to read the README included with the driver.}}

===ACPI daemon===
Also you'll need to install [[acpid]], if it isn't present on your system. [[acpid]] is a daemon that handles the ACPI events generated by the system. Read [[How to configure acpid]].

==Screen blanking (Standby)==
Make sure you have
Option "DPMS"
in the Monitor section of your {{path|/etc/X11/XF86Config}} or {{path|/etc/X11/xorg.conf}}.

Running {{cmd|xset +dpms}} and then {{cmd|xset dpms force off}} will turn off the backlight on a laptop screen. 

Note that this may not work in combination with {{cmd|echo -n "mem" > /sys/power/state}} because switching to console causes the backlight to come back on before sleeping.

==Suspend to RAM (Sleep)==
ACPI Sleep/suspend-to-ram with recent 2.6.x kernels usually works fine. Have a look at the [[How to configure acpid|acpid configuration HOWTO]]. It includes a specific example for going to sleep on lid close.

The following glitches may or may not occur in relation to suspending to RAM:
* If your suspend is failing, and a {{cmdroot|tail /var/log/acpid}} shows "Permission denied" errors, be sure that your new ACPI event and action scripts have the appropriate permissions.
* When resuming from a suspend-to-ram the display might remain black or might only show the pre-suspend output (the system is still rebootable via {{key|ctrl}}{{key|alt}}{{key|del}}). Look [[Problem with display remaining black after resume|here]] for solutions.
* When your system is equiped with a Radeon Mobility graphic controller your [[Problem with LCD backlight remaining on during ACPI sleep|LCD backlight may not turn off automatically]]. Use [[radeontool]] to switch off your backlight prior suspend in your sleep action script.
* Also, you might want to take note of the [[Problem with high power drain in ACPI sleep]].

==Suspend to disk (Hibernate)==
There are two drivers for this available:
* swsusp, which is in the kernel and
* [http://developer.berlios.de/projects/softwaresuspend/ SoftwareSuspend2] which is more feature rich, but not yet in the kernel, so you have to patch it in yourself
Both are reported to work fine as long as you use open-source graphic drivers. A comparison of the features can be found on [http://softwaresuspend.berlios.de/features.html this page].

Just in case you are in doubt...yes, it is safe in both cases to use the same swap partition as active swap and as suspend partition.

===using swsusp===
Software Suspend (swsusp) is included in the 2.6 kernel series. It seems like no patches for 2.4 kernels are available.

To enable software suspend change your kernel config as follows:
:{{kernelconf||||Power management options|Power management support|<*>|CONFIG_PM}}
:{{kernelconf||||Power management options|Software Suspend|<*>|CONFIG_SOFTWARE_SUSPEND}}
:{{kernelconf||||Power management options|Default resume partition|[/dev/resume_partition]|CONFIG_PM_STD_PARTITION}}

<tt>/dev/resume_partition</tt> needs to be replaced by the swap partition you want to use for suspending. (Use {{cmdroot|fdisk -l /dev/hda}} if unsure.)

You can override the default resume partition anytime by giving {{bootparm|resume|/dev/resume_partition}} as kernel boot parameter.
Also, in case you suspended, but want to boot up normally (without resuming from the saved image - losing all data that was unsaved at suspend time), you can give the <tt>noresume</tt> kernel boot parameter.

(In my case, and according to reports from several people, suspending does not work if resume_partition is specified in the kernel config (my version is 2.6.12-3 from kernel.org). It works as a charm if one specifies the resume partition as a kernel parameter instead.)

To suspend you can either do a simple {{cmdroot|echo -n 4 > /proc/acpi/sleep}} (recommended) or use the [http://softwaresuspend.berlios.de/old-site/swsusp/sysvinit-2.76-v2-for_swsusp-v5.tar.gz patched SysVInit] and call {{cmdroot|swsusp}} or {{cmdroot|shutdown -z now}}.

Ideally you would do this from a script like {{path|/etc/acpi/actions/hibernate.sh}}. It has proven to be a good idea to shutdown the following processes/drivers within the script before you do the actual suspend.
*any running mysql server
*the linuxant driver may require stopping in a acpi script as well. {{cmdroot|dldrstop}} does the trick.

Afterwards you might want to enable them again, as well as run a script that does necessary configurations according to the ac power state.
Furthermore, the system clock is not readjusted automatically, so you will probably also want the do that from that script (i.e. by restarting your systemclock bootup script).

If the sound output is silent after resume, these commands might help to get sound to work again without reloading any modules:

amixer set Master mute >/dev/null 2>&1
amixer set PCM mute >/dev/null 2>&1
amixer set Master unmute >/dev/null 2>&1
amixer set PCM unmute >/dev/null 2>&1

Finally you should take note that swsusp does not set the ACPI S4 state. Instead it goes to S5. This means that the machine itself doesn't know that it was suspend rather than shutdown. Hence you can i.e. boot a parallel installed other operating system and resume your linux session later, as long as you don't touch the swap partition the image was saved to.

===using SoftwareSuspend2===
First apply Software Suspend 2 patches from http://softwaresuspend.berlios.de/ if they are not already in your kernel.

Be sure to also read the http://softwaresuspend.berlios.de/HOWTO.html

These are the options for the kernel. Make sure to change the <tt>/dev/resume_partition</tt> to your swap partition, i.e. <tt>/dev/hda5</tt>.

# Software Suspend 2
CONFIG_SOFTWARE_SUSPEND2=y
CONFIG_SOFTWARE_SUSPEND2_BUILTIN=y
CONFIG_SOFTWARE_SUSPEND_SWAPWRITER=y
CONFIG_SOFTWARE_SUSPEND_LZF_COMPRESSION=y
CONFIG_SOFTWARE_SUSPEND_TEXT_MODE=y
CONFIG_SOFTWARE_SUSPEND_DEFAULT_RESUME2="/dev/resume_partition"
# CONFIG_SOFTWARE_SUSPEND_KEEP_IMAGE is not set
CONFIG_SOFTWARE_SUSPEND_CHECK_RESUME_SAFE=y
# CONFIG_SOFTWARE_SUSPEND_DEBUG is not set
# CONFIG_SOFTWARE_SUSPEND_DEVELOPER is not set

Next, compile and install the kernel.

In the meantime, add the following to the kernel parameters: {{bootparm|resume2|swap:/dev/resume_partition}}. Again change <tt>/dev/resume_partition</tt> to your swap partition.

Install the hibernation script:
*For {{Gentoo}} users: emerge hibernate-script 
*For {{Fedora}} users: kernel and hibernate RPMs are available at http://mhensler.de/swsusp/ 
*For all other users, check the home page for packages (deb, i386 rpm, tgz, and source rpm) from http://softwaresuspend.berlios.de/
*{{Debian}} users using initrd image, make sure you copy [http://dagobah.ucc.asn.au/swsusp/2.0.0.102/swsusp-initrd.sh swsusp-initrd.sh] script to your {{path|/etc/mkinitrd/scripts}} directory before creating initrd image.

Restart using the new kernel and run the script to test it: {{cmdroot|/usr/sbin/hibernate}}

How to make ACPI work

2005-08-23T16:27:13Z

Ychao: /* Suspend to RAM (Sleep) */

==general==
===Kernel configuration===
First of all you'll have to enable ACPI support in your kernel (if your distro doesn't already have an ACPI enabled kernel).
To do this open your kernel config and enable ACPI Power Management:
{{kernelconf||||Power management options|Power Management support|<*>|CONFIG_PM}}
{{kernelconf||||Power management options|ACPI|<*>|CONFIG_ACPI_SLEEP}}

You'd most likely want to enable the following ACPI options:
{{kernelconf|||Power management options|ACPI|Sleep States|<*>|CONFIG_ACPI_SLEEP}}
{{kernelconf|||Power management options|ACPI|AC Adapter|<*>|CONFIG_ACPI_AC}}
{{kernelconf|||Power management options|ACPI|Battery|<*>|CONFIG_ACPI_BATTERY}}
{{kernelconf|||Power management options|ACPI|Fan|<*>|CONFIG_ACPI_FAN}}
{{kernelconf|||Power management options|ACPI|Processor|<*>|CONFIG_ACPI_PROCESSOR}}
{{kernelconf|||Power management options|ACPI|Thermal Zone|<*>|CONFIG_ACPI_THERMAL}}

If you prefer editing your {{path|.config}} file directly, you should set at least the following variables:
CONFIG_PM=y
CONFIG_ACPI_BOOT=y
CONFIG_ACPI_INTERPRETER=y
CONFIG_ACPI_SLEEP=y
CONFIG_ACPI_SLEEP_PROC_FS=y
CONFIG_ACPI_AC=y
CONFIG_ACPI_BATTERY=y
CONFIG_ACPI_BUTTON=y
CONFIG_ACPI_FAN=y
CONFIG_ACPI_PROCESSOR=y
CONFIG_ACPI_THERMAL=y
CONFIG_ACPI_BUS=y
CONFIG_ACPI_EC=y
CONFIG_ACPI_POWER=y
CONFIG_ACPI_PCI=y
CONFIG_ACPI_SYSTEM=y

Then recompile your kernel.

===IBM specific ACPI driver===
Unfortunately, special drivers for ACPI on ThinkPads were not included with kernels prior 2.6.10. So you'll have to compile one yourself or get it as precompiled module for your kernel.

You have the choice between [[thinkpad-acpi]] and [[ibm-acpi]], with the latter being the recommended one.

If you use a post-2.6.10 kernel and you want to use [[ibm-acpi]], it is recommended to look on its projects page for a possibly newer version.

{{HINT|In general it is a good idea to read the README included with the driver.}}

===ACPI daemon===
Also you'll need to install [[acpid]], if it isn't present on your system. [[acpid]] is a daemon that handles the ACPI events generated by the system. Read [[How to configure acpid]].

==Screen blanking (Standby)==
Make sure you have
Option "DPMS"
in the Monitor section of your {{path|/etc/X11/XF86Config}} or {{path|/etc/X11/xorg.conf}}.

Running {{cmd|xset +dpms}} and then {{cmd|xset dpms force off}} will turn off the backlight on a laptop screen. 

Note that this may not work in combination with {{cmd|echo -n "mem" > /sys/power/state}} because switching to console causes the backlight to come back on before sleeping.

==Suspend to RAM (Sleep)==
ACPI Sleep/suspend-to-ram with recent 2.6.x kernels usually works fine. Have a look at the [[How to configure acpid|acpid configuration HOWTO]]. It includes a specific example for going to sleep on lid close.

The following glitches may or may not occur in relation to suspending to RAM:
* With a 2.6.9 or 2.6.10 kernel, when resuming from a suspend-to-ram the display might remain black (the system is still rebootable via {{key|ctrl}}{{key|alt}}{{key|del}}). This can be fixed by adding {{bootparm|acpi_sleep|s3_bios}} to the kernel boot parameters. It seems this problem is solved in 2.6.11-rc1, but is reported to be needed on 2.6.12.3.
* When your system is equiped with a Radeon Mobility graphic controller your [[Problem with LCD backlight remaining on during ACPI sleep|LCD backlight may not turn off automatically]]. Use [[radeontool]] to switch off your backlight prior suspend in your sleep action script.
* Also, you might want to take note of the [[Problem with high power drain in ACPI sleep]].
* You may experience problems when using {{cmdroot|echo standby > /sys/power/state}} (machine goes to sleep and wakes up immediately). This can be avoided by using {{cmdroot|echo -n 3 >/proc/acpi/sleep}} to get it to sleep. This can be also happen if hotplug daemon is still running.
* Problems with the serial port of the port replicator after the wake up from ram have also been experienced.
* Crash on resume
** ...when using ATI proprietary drivers can be solved by using [http://freshmeat.net/projects/vbetool/ vbetool].
** ...might be solved by disabling ''APIC'' (@Processor type and features) in the kernel configuration
* If your suspend is failing, and a tail of {{path|/var/log/acpid}} shows "Permission denied" errors, be sure that your new ACPI event and action scripts have the appropriate permissions
* Due to the fact that Sonoma chipset based laptops (T43, T43p) utilize the SATA layer for disk access and SATA does not have power-management support yet Suspend to RAM does not work on these machines. However, Jens Axboe's patch ([http://marc.theaimsgroup.com/?l=linux-kernel&m=111504542402455&w=2] LKML posting) provides SATA power-management support and makes Suspend to RAM work on the T43 at least. (Tested on 2.6.12rc6 which the patch applies to with some offsets. T43p not tested but should work as well. X41: uses SATA also and works with ACPI sleep after this patch applied (with acpi_sleep=s3_bios), but still hung when using APM (acpi=off). R52 uses SATA and sleep doesn't work, so it is probably affected too)
