== Linux driver - OpenSource ==
The open-source "radeon" driver works quite well for 2D. It gets a bit hotter than the fglrx. 3D is still in early development but some open source games work.
Wine support is very dogy with the radeon driver dont expect anything to work with it.

== Linux driver - Proprietary ==
Please look at the [[fglrx]] page for details

Fan control scripts

2010-06-16T14:21:12Z

Manuel:

{| width="100%"
|style="vertical-align:top;padding-right:20px;width:10px;white-space:nowrap;" | __TOC__
|style="vertical-align:top" |
This page provides several scripts for controlling the ThinkPad's system fan according the its [[thermal sensors]] (overriding the embedded controller), in order to reduce [[problem with fan noise|fan noise]] and decrease [[how to reduce power consumption|power consumption]].

{{WARN|These scripts rely on undocumented hardware features and override nominal hardware behavior. They may thus cause arbitrary damage to your laptop or data. Watch your temperatures!}}
{{NOTE|Closed-loop fan control requires a thermal sensor sweep, which is an expensive operation. The firmware doesn't update the sensors more than once every 2s, so care should be taken not to waste resources by reading them too often.}}
|}

==Variable speed control scripts==
The following scripts sets the fan speed according to the system's [[thermal sensors]]. In addition, they include a hack for preventing the annoying fan pulsing that occurs on some systems. Note that the fan levels, thresholds and anti-pulsing hacks are system-specific, so you may need to adjust them.

===Comprehensive <tt>bash</tt> script with fine control over fan speed===
This script works with any recent Linux kernel (2.6.14 and higher). It requires the [[ibm-acpi]] module to be loaded with the <tt>experimental=1</tt> module parameter (e.g., {{cmdroot|1=modprobe ibm_acpi experimental=1}}).

In Linux 2.6.22 and higher you need to additionally pass fan_control=1 to the module thinkpad_acpi (e.g., {{cmdroot|1=modprobe thinkpad-acpi experimental=1 fan_control=1}})

The code lets you define a temperature range for each [[thermal sensors|thermal sensor]]. The script computes the fan level needed by each sensor based on the configured range, and then sets the the actual fan level to the slowest that will satisfy all sensors (plus some hysteresis to avoid fluctiations). It also includes a workaround for the [[Problem with fan noise|pulsing noise]] problem. The script provides an (optional) daemon mode and logging to syslog. The method of controlling fan speed is documented [[How to control fan speed|here]].

The system hard disk temperature is monitored as well, using the hard disk's internal sensor. This works only on certain Hitachi disks and requires kernel >= 2.6.19-rc1 or the ide driver, since it uses a [[Thermal Sensors#Hitachi_harddisks_SENSE_CONDITION_temperature_sensor|non-standard method]] for reading the temperature without causing a head unload or spinup.

The code:
* {{CodeRef|tp-fancontrol}}

Current options:

Usage: ./tp-fancontrol [OPTION]...

Available options:
-s N Shift up the min temperature thresholds by N degrees
(positive for quieter, negative for cooler).
Max temperature thresholds are not affected.
-S N Shift up the max temperature thresholds by N degrees
(positive for quieter, negative for cooler). DANGEROUS.
-t Test mode
-q Quiet mode
-d Daemon mode, go into background (implies -q)
-l Log to syslog
-k Kill already-running daemon
-u Tell already-running daemon that the system is being suspended
-p Pid file location for daemon mode
{{WARN|The list of temperature ranges used in this script is much more liberal than the rules used by the embedded controller firmware, and is derived mostly from anecdotal evidence, hunches and wishful thinking. It is also model-specific - see [[thermal sensors]].}}

====init script for the comprehensive script====

This is optional. It assumes that the above <tt>tp-fancontrol</tt> script is saved at {{path|/usr/bin/tp-fancontrol}}.
* Init script: {{CodeRef|tp-fancontrol.init}} (save as {{path|/etc/init.d/tp-fancontrol}})
* Init script (Debian): {{CodeRef|tp-fancontrol.init.debian}} (save as {{path|/etc/init.d/tp-fancontrol}})
* Configuration file for init script: {{CodeRef|tp-fancontrol.conf}} (save as {{path|/etc/tp-fancontrol.conf}})

===Simple <tt>bash</tt> script with fine control over fan speed (requires kernel patch)===
The following is a simpler patch (without extra features like daemon mode and logging). It requires the [[patch for controlling fan speed]] or a recent kernel (>=2.6.19).

{{CodeRef|tp-fancontrol-basic}}

===tp-fan: Automatic daemon with GTK+ GUI===
Provides easy setup and monitoring through graphical GTK+ interface. Temperature thresholds can be set separately for each sensor since version 0.90.

At the moment packages are available for Ubuntu 7.10 and 8.04. However, porting to other distributions or manual setup should be easy.

* Home page: http://www.gambitchess.org/moin.py/tpfan

===thinkfan: A minimalist fan control program===
Written in C to use as little CPU power as possible. Configuration is done via a simple text file, by providing (FAN_LEVEL, LOWER_LIMIT, UPPER_LIMIT) tuples. Inspired by i8kfan. Requires thinkpad_acpi with fan_control=1. Just released version 0.7, which now allows a more fine-grained control over temperature limits.

* Download here: http://sourceforge.net/projects/thinkfan/

==Fan enable/disable scripts==
The following scripts were written before it was known [[patch for controlling fan speed|how to control the fan speed]], so they only toggle between fan disabled and default (noisy) fan behavior. In some models, they also do not monitor all available [[thermal sensors]].

===<tt>sh</tt> script example===
{{CodeRef|fan-enable-basic}}

===<tt>sh</tt> script with more features===
{{CodeRef|fan-enable-extended}}

===<tt>sh</tt> script with extra safety functionality===
ibm_acpi usually works well. But to rely on it completely, this script provides some extra safety functionality:
# It catches various signals and turns the fan on before it quits.
# It turns off the fan under very strict conditions, leaving it on when unexpected errors occur.

{{CodeRef|fan-enable-safe}}

==Init scripts==

===Init script example===

{{CodeRef|fan-enable.init}}

===Init script example for gentoo===
Assume one of the above control scripts is {{path|/usr/sbin/ibm-fancontrold}}, for gentoo use the following init script in /etc/init.d/ibm-fancontrol.
Copy the script to {{path|/etc/init.d/ibm-fancontrol}}, then do

# rc-update add ibm-fancontrol default

This will add the init script to the default runlevel.

{{CodeRef|ibm-fancontrol.init}}

===Init script example for rh/fedora===
Assume one of the above control scripts is {{path|/sbin/tp-fancontrold}},
copy the script to {{path|/etc/init.d/tp-fancontrol}}, then do

# chkconfig --add tp-fancontrol

This will add the init script to the default runlevel.

{{CodeRef|tp-fancontrol-fc.init}}

You'd have to install also "kernel-module-ibm-acpi" package.

==Other==

===tpfand===
This little piece of python code is only there to speed up your fan in a T400 with an ATI card cause the fglrx driver does not control the fan speed which leads to overheating while gaming or do other graphic stuff with the ati chip. This script relies on the normal bios control of the fan. If the laptop gets to hot it will speed up the fan to max speed (somehow the bios does not do this ??!!) and re-enables the bios control on a certain temperature. This was only tested on a T400 with ATI chip.
You can just run in in the background as root. It is very chatty and writes in a logfile in /tmp. It should work with any Thinkpad who has /proc/acpi/imb/fan interface.
[http://pastebin.ca/1884323 tpfand]

Tested on:
T400 with Radeon HD 3400
Please test on other models with ATI chip.

===fanctrld===
[http://log.does-not-exist.org/archives/2005/08/13/2043_t_43_fan_control_daemon.html fanctrld] is a daemon (written in C) that controls the Thinkpad's fan. The basic approach is to monitor both temperature and fan speed. The fan is enabled when a certain temperature is exceeded, and disabled when the BIOS slows down the fan below a certain speed.

===ThinkPad Fan Control GTK GUI tool===

[http://www.gambitchess.org/moin.py/ThinkPad_Fan_Control A GTK GUI program (packaged for Ubuntu Gutsy Gibbon 7.10)] may also help.

For those using Ubuntu 8.10 and recent Thinkpad models (eg: X200), this is the fan control packages to use: sudo apt-get install tpfand tpfan-admin tpfand-profiles (The packages are part of the main ubuntu repository). It solves the problem of a constantly-on fan. I don't think there are yet profiles for those newer thinkpad models, but it's fairly easy to manually configure the right thresholds. For reference, this is the /etc/tpfand.conf I use for my X200:

enabled = True

override_profile = True

0. Sensor 0 = 0:0 50:3 58:5 67:8

1. Sensor 1 = 0:0 55:3 62:5 69:8

2. Sensor 2 = 0:255

3. Sensor 3 = 0:0 48:3 61:5 69:8

4. Sensor 4 = 0:0 43:3 50:8

5. Sensor 5 = 0:255

6. Sensor 6 = 0:0 40:8

7. Sensor 7 = 0:255

==Ideas for improvement==
* Use the [[HDAPS]] sensor to automatically lower the temperature thresholds when the laptop is moving. Prolonged movement usually happens when the laptop is on the user's lap (see [[Problem with hot surfaces]] for implications), or when in a moving vehicle where fan noise is typically overshadowed by vehicle noise.
* Use a [http://en.wikipedia.org/wiki/PID_controller PID controller] feedback loop instead of simple thresholds.
* Monitor the UltraBay disk temperature too.

* [[How to control fan speed]]
* Shimodax's ThinkPad fan control tool for a Windows offers functionality similar to these scripts; see the [http://forum.thinkpads.com/viewtopic.php?t=17715 forum discussion] at thinkpads.com.
* Yury Polyanskiy has a [http://mailman.linux-thinkpad.org/pipermail/linux-thinkpad/2005-November/030697.html kernel patch] for automatic fan control in kernelspace (only enable/disable based on maximum temperature).

Install Ubuntu 9.04 (Jaunty Jackalope) on a ThinkPad T400

2009-07-24T19:07:57Z

Manuel: /* Active Protection System */

[[:Category:T400|T400]]

==Before Installation==

Before you can start Ubuntu from CD or USB you have to change two BIOS settings:
* Change to Internal or ATI Graphics with Config --> Display --> Graphics Device --> [Integrated graphics] or [Discrete Graphics]
* Disable OS Detection for Switchable Graphics. Otherwise it will mysteriously switch back to Switchable Graphics.

Now you can boot your Live-CD, connect to Wireless Lan, and install the OS.

==What works out of the box?==

*Wireless with iwlagn driver ([[Intel WiFi Link 5100/5300 WLAN controller]])
**G mode + WEP and WPA2 PSK
**with status LED and everything!
*Wireless with ath5k driver (ThinkPad 11b/g Wireless LAN mini PCI Express Adapter III (Atheros AR5007EG/AR2425 Chipset))
** jockey-gtk gives you the option of installing MadWIFI. I did not try that since ath5k works for me.
*Bluetooth
**Even with [[Bluetooth Laser Mouse]]
*[[Ethernet Controllers#Intel Gigabit (10/100/1000)|Intel Gigabit Ethernet Controller]]

*Intel driver for Integrated Graphics (Intel Integrated [[Intel GMA 4500MHD]])
** with 3D acceleration out-of-the-box
*ATI [[fglrx]] driver for Discrete Graphics ([[ATI Mobility Radeon 3470]] graphics)
**To enjoy 3D acceleration, you have to install the proprietary [[fglrx]] Driver. (for example with the jockey-gtk tool)
*VGA/HDMI output

*Sound card
**To use your internal microphone you maybe have to change to "HDA Intel CONEXANT Analog (ALSA)" in audio-settings.
*Optical drive (Including DVD burning)
*built-in webcam (tested with skype, cheese and vlc media player)
*7-in-1 card reader from Ricoh (MMC, Memory Stick, Mem Stick Pro, SD, SDHC, XD, XD Type H Memory)
*Touchpoint and Trackpad
**Including scroll at the right side of the pad by default. (for scrolling with the middle mouse button, see below!)

*Control buttons/Hotkeys
**Volume control buttons
**Screen brightness control (FN + Home/End)
**Thinklight control (FN + PgUp)
**WLAN/BT/OFF toggle (Fn+F5 press once: Wlan and BT off/Press second time: BT off, Wlan on/Third time: BT on, Wlan off/Press another time: BT and Wlan on)
**To add a bluetooth-only-toggle (Fn+F6) that doesn't affect WLAN take a look [[ThinkPad_Bluetooth_with_Enhanced_Data_Rate_(BDC-2)|here]]
**Wlan/BT hardware switch
**Media player control (FN + arrows)
**Browser history buttons
**Switch to extern Monitor (FN + F7 press once: picture on both monitors/Second time: on external Monitor/Third time: Laptop monitor)
**Suspend shortcut (FN + F4)
**Hibernate shortcut (FN + F12)
**Battery info shortcut (FN + F3)
**Screenlock shortcut (FN + F2)
**dock eject button (FN + F9) not tested yet!
**[[ThinkVantage Button]] (You only have to allocate a programm!)

*Some ACPI features
**Battery status, power graphs and history (tested with an single 6-Cell battery)
**Lid states and events
*Suspend/Hibernate

==What needs some Tweaks?==

===Mute button===

The Mute button only mutes the sound but no induction in the gnome volume indicator.
To fix this you must edit you grub menu.lst and add a kernel option acpi_osi="Linux" .

first back up your menu list
> sudo cp /boot/grub/menu.lst{,.orig}

Edit it
> sudo vim /boot/grub/menu.lst

Look for a line that looks something like this:
# kopt=root=UUID=<the disk partition id> ro

Add the kernel option to the end of the line:
# kopt=root=UUID=<the disk partition id> ro acpi_osi="Linux"

Save the file, then update grub
> sudo update-grub

===Postinstall-Script for this Workarounds===

This script:
*enables scrolling with trackpoint
*enables FN + F8 to switch on/off trackpad
*makes the recommended Workaround for the harddrive-Bug
*writes BATT_HD_POWERMGMT=200 (also to disable permanent Harddrive-parking )
*enables the Menu-Key

Step for Step:

1.Save this script as a textfile on your Desktop

2.Open the Terminal

3.Write this to change directory to Desktop

cd Desktop

4.Then type this line to set rights to read/write and execute (replace textfile with your filename!)

chmod 775 textfile

5.To get administrator rights type:

sudo su

6.Type your password

7.Execute the script

./textfile

8. If the script doesn't lead to success, you could try

sudo rm /var/cache/hald/fdi-cache
sudo /etc/init.d/hal restart

====Scrolling with Trackpoint====

Create a new file called /etc/hal/fdi/policy/mouse-wheel.fdi typing:

sudo gedit /etc/hal/fdi/policy/mouse-wheel.fdi

And fill it with this code:

<?xml version="1.0" encoding="UTF-8"?> 

<match key="info.product" string="TPPS/2 IBM TrackPoint">
<merge key="input.x11_options.EmulateWheel" type="string">true</merge>

(Based on code from [http://mvogt.wordpress.com/2008/08/15/xorg-evdev-and-emulatewheel/ Michael Vogt] and adapted to support both vertical and horizontal scrolling.)

====Enabling Touchpad on/off key====

Source: [[https://help.ubuntu.com/community/SynapticsTouchpad#shmconfig]]
The SHMConfig is now controlled through hal. In the past this was done through xorg.conf

You have to add the file
{{cmduser|sudo gedit /etc/hal/fdi/policy/shmconfig.fdi}}
with the following content:
<?xml version="1.0" encoding="UTF-8"?>
<deviceinfo version="0.2">
<device>
<match key="input.x11_driver" string="synaptics">
<merge key="input.x11_options.SHMConfig" type="string">True</merge>
</match>
</device>
</deviceinfo>

After this change please reboot. Restarting hal doesn't help.

====Menu-Key====

Taken from '''Bug [https://bugs.launchpad.net/ubuntu/+source/linux/+bug/287428 #287428]''' "Menu key emits XF86WakeUp on Thinkpad X61s":

Václav Šmilauer wrote:
"When I press the menu key on Thinkpad X61s, it doesn't do anything. I checked with xev and the generated keycode is 151 (xev-reported), which is mapped to <I151> and this, in turn to XF86WakeUp.
I tried diferent keyboard models for Thinkpads, bot none of them worked in this respect. A temporary solution was to replace "XF86WakeUp" with "Menu" in /usr/share/X11/xkb/symbols/inet:86, where <I151> is mapped."

'''The Workaround in short:'''

sudo gedit /usr/share/X11/xkb/symbols/inet

Press Str + F to search for '''"I151"''' and write

'''"Menu"''' instead of '''"XF86WakeUp"''' in this line!

====Notebook-Harddrive Bug====

https://wiki.ubuntu.com/PowerManagement#8.10%20(Intrepid):

"Many of the previous issues have been addressed in Intrepid. All you need to do is:
"ENABLE_LAPTOP_MODE=true" in /etc/default/acpi-support (Bug 244838 fixed in acpi-support 0.111?)

You can also change "BATT_HD_POWERMGMT=1" in /etc/laptop-mode/laptop-mode.conf to an higher value to stop permanent harddrive-parking!

====[[Active Protection System]]====

'''APS with DKMS support for tp_smapi, visit: http://code.google.com/p/tp-smapi-dkms-module/'''

If you use APS with DKMS then you don't need to rebuild the module after kernel switch/update.

http://www.thinkwiki.org/wiki/Tp_smapi#t…s_0x1600-0x161f

'''Here is a Step by Step guidance [[How to protect the harddisk through APS]] with Kernel 2.6.28!'''

At first you have to delete existing kernel modules to make space for the new ones (Press ENTER after each line):

sudo rm /lib/modules/$KVER/kernel/ubuntu/misc/thinkpad_ec.ko
sudo rm /lib/modules/$KVER/kernel/ubuntu/misc/tp_smapi.ko
sudo rm /lib/modules/$KVER/kernel/drivers/hwmon/hdaps.ko

Then downlaod the newest packages:

You will need
*tp_smapi-0.4 from here: http://sourceforge.net/project/showfiles.php?group_id=1212&package_id=171579
*hdapsd-20090401.tar.gz from here: http://sourceforge.net/project/showfiles.php?group_id=138242&package_id=308030
*gnome-hdaps-applet-20081204.tar.gz from here: http://www.zen24593.zen.co.uk/hdaps/

Save this things on your Desktop and unpack them, e.g.

tar xvfz hdapsd-20090401.tar.gz
tar xvfz tp_smapi-0.40.tgz
tar xvfz gnome-hdaps-applet-20081204.tar.gz

Then open the Terminal and type this to change into the tp_smapi directory:

cd Desktop/tp_smapi-0.40

Then try to load the kernel modules:

make load HDAPS=1 FORCE_IO=1

If there is written "drivers successfully loaded", you can type this for installation:

make install HDAPS=1 FORCE_IO=1

To laod this modules on startup you have to write them into the /etc/modules file:

sudo gedit /etc/modules

Append this to the file:

thinkpad_ec
tp_smapi
hdaps

We also need options to load this modules correctly. They have to be written in /etc/modprobe.d/local.conf

sudo gedit /etc/modprobe.d/local.conf

Fill the file with this code

# enable thinkpad_ec
options thinkpad_ec force_io=1

# option to correctly set tilting through hdaps sensor
options hdaps invert=1

Now you can try, if the modules are loaded yet. Do so with

lsmod | grep hdaps

if not perform:

sudo modprobe thinkpad_ec tp_smapi hdaps

Then install this packages:

sudo apt-get install hdaps-utils hdapsd

Afterwards you can test hdaps-gl (with typing hdaps-gl in terminal) which shows the position of your Laptop.

hdapsd is not working yet. Therefore we need to compile our newer version downloaded before.

cd Desktop/hdapsd-20090401/
./configure --prefix=/usr/
make
sudo make install

If compilation and installation succeeded, you can test it by typing this into your terminal:

sudo hdapsd -d sda -s 15 -a -v -y

If you suddenly move your laptop the output will change! (stop it with pressing Str + C)

The last step is, to copy an overworked initiation-script over the existing one.

The first line will download it, the second will set rights and the third one copies it to the right position. (Press ENTER after each!)

wget http://www.unet.univie.ac.at/~a0604095/hdapsd
sudo chmod 733 hdapsd
sudo cp hdapsd /etc/init.d/

Now you can start hdapsd with typing

sudo /etc/init.d/hdapsd start

After an reboot everything should start automatically and work correctly! You can change the sensitivity value and other things in this file: "'''/etc/default/hdapsd'''".
To see the effects you have to type "sudo /etc/init.d/hdapsd restart" to restart hdapsd!

To install the gnome-panel-applet type this lines into the terminal:

sudo apt-get install libpanel-applet2-dev
cd Desktop/gnome-hdaps-applet-20081204
gcc $(pkg-config --cflags --libs libpanelapplet-2.0) -o gnome-hdaps-applet gnome-hdaps-applet.c
sudo cp gnome-hdaps-applet /usr/bin/
sudo mkdir /usr/share/pixmaps/gnome-hdaps-applet/
sudo cp *.png /usr/share/pixmaps/gnome-hdaps-applet/
sudo cp GNOME_HDAPS_StatusApplet.server /usr/lib/bonobo/servers/

The first line is to install required deps, second line is to move to the source directory (we have downloaded it looong time ago!), then we compile it and copy the files to several positions. After an reboot you can add this applet to the panel!

Please feel free to correct mistakes. If you have trouble, don't be shy and contact me with jabber: jango4@jabber.org

==What doesn't work at the moment?==

====[[Integrated Fingerprint Reader]]====

There is a new chipset build in, the "AuthenTec AES2810". So neither the [http://thinkfinger.sourceforge.net thinkfinger] nor the [http://www.reactivated.net/fprint/wiki/Main_Page fprint] Project support this Device at the moment.

lsusb:
Bus 002 Device 004: ID 08ff:2810 AuthenTec, Inc.

Daniel from fprint Project wrote in their mailing list, that support for our device is in development!
For more information look here: [http://reactivated.net/fprint/wiki/Unsupported_devices fprint Unsupported devices]

====[[Switchable Graphics]]====

Same Problem as with 8.10!

==Not tested yet==

==Upgrading from earlier versions of Ubuntu==

====Resume/Suspend problems====
If you have problems with resume/suspend, first try if it works from the LiveCD. If LiveCD works, the problem must be in your Ubuntu configuration.
Try reinstalling acpi-support and laptop-mode-tools:
sudo apt-get remove --purge laptop-mode-tools acpi-support
sudo apt-get install laptop-mode-tools acpi-support
If this doesn't help, check the files in /etc/hal/fdi/information directory and remove the unnecessary files.

[[:Category:T400|T400]]

==Before Installation==

Before you can start Ubuntu from CD or USB you have to change two BIOS settings:
* Change to Internal or ATI Graphics with Config --> Display --> Graphics Device --> [Integrated graphics] or [Discrete Graphics]
* Disable OS Detection for Switchable Graphics. Otherwise it will mysteriously switch back to Switchable Graphics.

Now you can boot your Live-CD, connect to Wireless Lan, and install the OS.

==What works out of the box?==

*Wireless with iwlagn driver ([[Intel WiFi Link 5100/5300 WLAN controller]])

==What needs some Tweaks?==

===Mute button===

The Mute button only mutes the sound but no induction in the gnome volume indicator.
To fix this you must edit you grub menu.lst and add a kernel option acpi_osi="Linux" .

first back up your menu list
> sudo cp /boot/grub/menu.lst{,.orig}

Edit it
> sudo vim /boot/grub/menu.lst

Look for a line that looks something like this:
# kopt=root=UUID=<the disk partition id> ro

Add the kernel option to the end of the line:
# kopt=root=UUID=<the disk partition id> ro acpi_osi="Linux"

Save the file, then update grub
> sudo update-grub

===Postinstall-Script for this Workarounds===

This script:
*enables scrolling with trackpoint
*enables FN + F8 to switch on/off trackpad
*makes the recommended Workaround for the harddrive-Bug
*writes BATT_HD_POWERMGMT=200 (also to disable permanent Harddrive-parking )
*enables the Menu-Key

Step for Step:

1.Save this script as a textfile on your Desktop

2.Open the Terminal

3.Write this to change directory to Desktop

cd Desktop

4.Then type this line to set rights to read/write and execute (replace textfile with your filename!)

chmod 775 textfile

5.To get administrator rights type:

sudo su

6.Type your password

7.Execute the script

./textfile

8. If the script doesn't lead to success, you could try

sudo rm /var/cache/hald/fdi-cache
sudo /etc/init.d/hal restart

====Scrolling with Trackpoint====

Create a new file called /etc/hal/fdi/policy/mouse-wheel.fdi typing:

sudo gedit /etc/hal/fdi/policy/mouse-wheel.fdi

And fill it with this code:

<?xml version="1.0" encoding="UTF-8"?>

(Based on code from [http://mvogt.wordpress.com/2008/08/15/xorg-evdev-and-emulatewheel/ Michael Vogt] and adapted to support both vertical and horizontal scrolling.)

====Enabling Touchpad on/off key====

Source: [[https://help.ubuntu.com/community/SynapticsTouchpad#shmconfig]]
The SHMConfig is now controlled through hal. In the past this was done through xorg.conf

You have to add the file
{{cmduser|sudo gedit /etc/hal/fdi/policy/shmconfig.fdi}}
with the following content:
<?xml version="1.0" encoding="UTF-8"?>
<deviceinfo version="0.2">
<device>
<match key="input.x11_driver" string="synaptics">
<merge key="input.x11_options.SHMConfig" type="string">True</merge>
</match>
</device>
</deviceinfo>

After this change please reboot. Restarting hal doesn't help.

====Menu-Key====

Taken from '''Bug [https://bugs.launchpad.net/ubuntu/+source/linux/+bug/287428 #287428]''' "Menu key emits XF86WakeUp on Thinkpad X61s":

Václav Šmilauer wrote:
"When I press the menu key on Thinkpad X61s, it doesn't do anything. I checked with xev and the generated keycode is 151 (xev-reported), which is mapped to <I151> and this, in turn to XF86WakeUp.
I tried diferent keyboard models for Thinkpads, bot none of them worked in this respect. A temporary solution was to replace "XF86WakeUp" with "Menu" in /usr/share/X11/xkb/symbols/inet:86, where <I151> is mapped."

'''The Workaround in short:'''

sudo gedit /usr/share/X11/xkb/symbols/inet

Press Str + F to search for '''"I151"''' and write

'''"Menu"''' instead of '''"XF86WakeUp"''' in this line!

====Notebook-Harddrive Bug====

https://wiki.ubuntu.com/PowerManagement#8.10%20(Intrepid):

"Many of the previous issues have been addressed in Intrepid. All you need to do is:
"ENABLE_LAPTOP_MODE=true" in /etc/default/acpi-support (Bug 244838 fixed in acpi-support 0.111?)

You can also change "BATT_HD_POWERMGMT=1" in /etc/laptop-mode/laptop-mode.conf to an higher value to stop permanent harddrive-parking!

====[[Active Protection System]]====

'''Here is a Step by Step guidance [[How to protect the harddisk through APS]] with Kernel 2.6.28!'''

At first you have to delete existing kernel modules to make space for the new ones (Press ENTER after each line):

sudo rm /lib/modules/$KVER/kernel/ubuntu/misc/thinkpad_ec.ko
sudo rm /lib/modules/$KVER/kernel/ubuntu/misc/tp_smapi.ko
sudo rm /lib/modules/$KVER/kernel/drivers/hwmon/hdaps.ko

Then downlaod the newest packages:

You will need
*tp_smapi-0.4 from here: http://sourceforge.net/project/showfiles.php?group_id=1212&package_id=171579
*hdapsd-20090401.tar.gz from here: http://sourceforge.net/project/showfiles.php?group_id=138242&package_id=308030
*gnome-hdaps-applet-20081204.tar.gz from here: http://www.zen24593.zen.co.uk/hdaps/

Save this things on your Desktop and unpack them, e.g.

tar xvfz hdapsd-20090401.tar.gz
tar xvfz tp_smapi-0.40.tgz
tar xvfz gnome-hdaps-applet-20081204.tar.gz

Then open the Terminal and type this to change into the tp_smapi directory:

cd Desktop/tp_smapi-0.40

Then try to load the kernel modules:

make load HDAPS=1 FORCE_IO=1

If there is written "drivers successfully loaded", you can type this for installation:

make install HDAPS=1 FORCE_IO=1

To laod this modules on startup you have to write them into the /etc/modules file:

sudo gedit /etc/modules

Append this to the file:

thinkpad_ec
tp_smapi
hdaps

We also need options to load this modules correctly. They have to be written in /etc/modprobe.d/local.conf

sudo gedit /etc/modprobe.d/local.conf

Fill the file with this code

# enable thinkpad_ec
options thinkpad_ec force_io=1

# option to correctly set tilting through hdaps sensor
options hdaps invert=1

Now you can try, if the modules are loaded yet. Do so with

lsmod | grep hdaps

if not perform:

sudo modprobe thinkpad_ec tp_smapi hdaps

Then install this packages:

sudo apt-get install hdaps-utils hdapsd

Afterwards you can test hdaps-gl (with typing hdaps-gl in terminal) which shows the position of your Laptop.

hdapsd is not working yet. Therefore we need to compile our newer version downloaded before.

cd Desktop/hdapsd-20090401/
./configure --prefix=/usr/
make
sudo make install

If compilation and installation succeeded, you can test it by typing this into your terminal:

sudo hdapsd -d sda -s 15 -a -v -y

If you suddenly move your laptop the output will change! (stop it with pressing Str + C)

The last step is, to copy an overworked initiation-script over the existing one.

The first line will download it, the second will set rights and the third one copies it to the right position. (Press ENTER after each!)

wget http://www.unet.univie.ac.at/~a0604095/hdapsd
sudo chmod 733 hdapsd
sudo cp hdapsd /etc/init.d/

Now you can start hdapsd with typing

sudo /etc/init.d/hdapsd start

After an reboot everything should start automatically and work correctly! You can change the sensitivity value and other things in this file: "'''/etc/default/hdapsd'''".
To see the effects you have to type "sudo /etc/init.d/hdapsd restart" to restart hdapsd!

To install the gnome-panel-applet type this lines into the terminal:

sudo apt-get install libpanel-applet2-dev
cd Desktop/gnome-hdaps-applet-20081204
gcc $(pkg-config --cflags --libs libpanelapplet-2.0) -o gnome-hdaps-applet gnome-hdaps-applet.c
sudo cp gnome-hdaps-applet /usr/bin/
sudo mkdir /usr/share/pixmaps/gnome-hdaps-applet/
sudo cp *.png /usr/share/pixmaps/gnome-hdaps-applet/
sudo cp GNOME_HDAPS_StatusApplet.server /usr/lib/bonobo/servers/

The first line is to install required deps, second line is to move to the source directory (we have downloaded it looong time ago!), then we compile it and copy the files to several positions. After an reboot you can add this applet to the panel!

Please feel free to correct mistakes. If you have trouble, don't be shy and contact me with jabber: jango4@jabber.org

==What doesn't work at the moment?==

====[[Integrated Fingerprint Reader]]====

There is a new chipset build in, the "AuthenTec AES2810". So neither the [http://thinkfinger.sourceforge.net thinkfinger] nor the [http://www.reactivated.net/fprint/wiki/Main_Page fprint] Project support this Device at the moment.

lsusb:
Bus 002 Device 004: ID 08ff:2810 AuthenTec, Inc.

Daniel from fprint Project wrote in their mailing list, that support for our device is in development!
For more information look here: [http://reactivated.net/fprint/wiki/Unsupported_devices fprint Unsupported devices]

====[[Switchable Graphics]]====

Same Problem as with 8.10!

==Not tested yet==

==Upgrading from earlier versions of Ubuntu==

====Resume/Suspend problems====
If you have problems with resume/suspend, first try if it works from the LiveCD. If LiveCD works, the problem must be in your Ubuntu configuration.
Try reinstalling acpi-support and laptop-mode-tools:
sudo apt-get remove --purge laptop-mode-tools acpi-support
sudo apt-get install laptop-mode-tools acpi-support
If this doesn't help, check the files in /etc/hal/fdi/information directory and remove the unnecessary files.

==What needs some Tweaks?==

===Mute button===

The Mute button only mutes the sound but no induction in the gnome volume indicator.
To fix this you must edit you grub menu.lst and add a kernel option acpi_osi="Linux" .

first back up your menu list
> sudo cp /boot/grub/menu.lst{,.orig}

Edit it
> sudo vim /boot/grub/menu.lst

Look for a line that looks something like this:
# kopt=root=UUID=<the disk partition id> ro

Add the kernel option to the end of the line:
# kopt=root=UUID=<the disk partition id> ro acpi_osi="Linux"

Save the file, then update grub
> sudo update-grub

===Postinstall-Script for this Workarounds===

At first you have to delete existing kernel modules to make space for the new ones (Press ENTER after each line):

sudo rm /lib/modules/$KVER/kernel/ubuntu/misc/thinkpad_ec.ko
sudo rm /lib/modules/$KVER/kernel/ubuntu/misc/tp_smapi.ko
sudo rm /lib/modules/$KVER/kernel/drivers/hwmon/hdaps.ko

Then downlaod the newest packages:

You will need

tar xvfz hdapsd-20090401.tar.gz
tar xvfz tp_smapi-0.40.tgz
tar xvfz gnome-hdaps-applet-20081204.tar.gz

Then open the Terminal and type this to change into the tp_smapi directory:

cd Desktop/tp_smapi-0.40

Then try to load the kernel modules:

make load HDAPS=1 FORCE_IO=1

If there is written "drivers successfully loaded", you can type this for installation:

make install HDAPS=1 FORCE_IO=1

To laod this modules on startup you have to write them into the /etc/modules file:

sudo gedit /etc/modules

Append this to the file:

thinkpad_ec
tp_smapi
hdaps

We also need options to load this modules correctly. They have to be written in /etc/modprobe.d/local.conf

sudo gedit /etc/modprobe.d/local.conf

Fill the file with this code

# enable thinkpad_ec
options thinkpad_ec force_io=1

# option to correctly set tilting through hdaps sensor
options hdaps invert=1

Now you can try, if the modules are loaded yet. Do so with

lsmod | grep hdaps

if not perform:

sudo modprobe thinkpad_ec tp_smapi hdaps

Then install this packages:

sudo apt-get install hdaps-utils hdapsd

Afterwards you can test hdaps-gl (with typing hdaps-gl in terminal) which shows the position of your Laptop.

hdapsd is not working yet. Therefore we need to compile our newer version downloaded before.

cd Desktop/hdapsd-20090401/
./configure --prefix=/usr/
make
sudo make install

If compilation and installation succeeded, you can test it by typing this into your terminal:

sudo hdapsd -d sda -s 15 -a -v -y

If you suddenly move your laptop the output will change! (stop it with pressing Str + C)

The last step is, to copy an overworked initiation-script over the existing one.

The first line will download it, the second will set rights and the third one copies it to the right position. (Press ENTER after each!)

wget http://www.unet.univie.ac.at/~a0604095/hdapsd
sudo chmod 733 hdapsd
sudo cp hdapsd /etc/init.d/

Now you can start hdapsd with typing

sudo /etc/init.d/hdapsd start

After an reboot everything should start automatically and work correctly! You can change the sensitivity value and other things in this file: "'''/etc/default/hdapsd'''".
To see the effects you have to type "sudo /etc/init.d/hdapsd restart" to restart hdapsd!

To install the gnome-panel-applet type this lines into the terminal:

sudo apt-get install libpanel-applet2-dev
cd Desktop/gnome-hdaps-applet-20081204
gcc $(pkg-config --cflags --libs libpanelapplet-2.0) -o gnome-hdaps-applet gnome-hdaps-applet.c
sudo cp gnome-hdaps-applet /usr/bin/
sudo mkdir /usr/share/pixmaps/gnome-hdaps-applet/
sudo cp *.png /usr/share/pixmaps/gnome-hdaps-applet/
sudo cp GNOME_HDAPS_StatusApplet.server /usr/lib/bonobo/servers/

The first line is to install required deps, second line is to move to the source directory (we have downloaded it looong time ago!), then we compile it and copy the files to several positions. After an reboot you can add this applet to the panel!

Please feel free to correct mistakes. If you have trouble, don't be shy and contact me with jabber: jango4@jabber.org

==What doesn't work at the moment?==

====[[Integrated Fingerprint Reader]]====

There is a new chipset build in, the "AuthenTec AES2810". So neither the [http://thinkfinger.sourceforge.net thinkfinger] nor the [http://www.reactivated.net/fprint/wiki/Main_Page fprint] Project support this Device at the moment.

lsusb:
Bus 002 Device 004: ID 08ff:2810 AuthenTec, Inc.

Daniel from fprint Project wrote in their mailing list, that support for our device is in development!
For more information look here: [http://reactivated.net/fprint/wiki/Unsupported_devices fprint Unsupported devices]

====[[Switchable Graphics]]====

Same Problem as with 8.10!

==Not tested yet==

==Upgrading from earlier versions of Ubuntu==

====Resume/Suspend problems====
If you have problems with resume/suspend, first try if it works from the LiveCD. If LiveCD works, the problem must be in your Ubuntu configuration.
Try reinstalling acpi-support and laptop-mode-tools:
sudo apt-get remove --purge laptop-mode-tools acpi-support
sudo apt-get install laptop-mode-tools acpi-support
If this doesn't help, check the files in /etc/hal/fdi/information directory and remove the unnecessary files.

Save power with Ubuntu 9.04 (Jaunty Jackalope) on a ThinkPad T400

2009-04-24T12:36:09Z

Manuel:

Hi

// have to read wiki syntax to format correctly//

==Basic information==

I have Thinkpad T400 WC8......

9 cell battery now 60% last 4.37 h

Idle consumtion after this tipps: 11-13 watts before th tipps i used 30-35 watts

I use the ATI Card with the fglrx drivers, unfortunatelly the have no option to save power.

I use powernowd, Gudiance Power manager and KDE4.2 powerdevil.

4 Gig RAM 2.26 GHz 250GB/5400

Hibernate and suspend work (sometimes, crap fglrx driver)

== Let's start: ==

Stop deamons you don't need with rcconf

Set wlan and bluetooth off (hardware switch)

Deaktivate the touchpad.

== My Bios Settings: ==

Bluetooth off

Modem off

Wake on lan off

Flash over lan off

Serial port off

Always USB off

CdromSpeed silent

Virttualisation off

Dockingstation off

== Script to save power ==

This script reduce the power consumtion to 13-16 watts

Save this script as '''/etc/rc.local''' and do chmod +x on it

Then modify '''/etc/kde4/kdm/Xsetup'''

and add:

'''exec /etc/rc.local'''

before exit 0

The script:

[http://de.pastebin.ca/1397527 think_powersave]

== Modify the xorg ==

Modify like this:

Section "Device"
Identifier "Configured Video Device"
Driver "fglrx"
......
Option "DynamicClocks" "true"
Option "PowerState" "1"
BusID "PCI:1:0:0"
EndSection

and

Section "Monitor"
Identifier "aticonfig-Monitor[0]-1"
Option "VendorName" "ATI Proprietary Driver"
Option "ModelName" "Generic Autodetecting Monitor"
Option "DPMS" "true"
EndSection

== Use powernowd==

install powernowd

Then modify '''/etc/default/powernowd'''

with this parameters(add after -q with a space after q):

-m 2 -l 20 -u 70 -s 300000

==Powerdevil settings==

Powersave Profile Settings:

general:
Disable Composite

Dim after 1 min

Idle for +20 min shutdown

Lid: lock screen

any Button: Show logout dialog

screen:

Screen Brighness 75 %

enable display power management

standby 3 min
suspend 6 min
power off 8min

cpu:

scaleing: userspace
sheme: powersave

==Gudiance PowerManager==

Lock screen after resume

Battery Powered:

Brightness 75%

drops below 10 min --> shutdown
idle more than XXX do nothing
cpu freq: dynamic (changed from powernowd then)
Lid: lock screen

==Blacklist==

echo "blacklist pcmcia" >> /etc/modprobe.d/blacklist.conf

echo "blacklist yenta_socket" >> /etc/modprobe.d/blacklist.conf

Well good luck and have fun I think if you use the intel card you can additionally save 3-5 watts

Idle consumptions

2009-04-20T19:12:36Z

Manuel:

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.

# The sched_mc_power_savings tunable can save a significant amount of power (multiple Watts) under workloads where there is idle time in the system. To enable the tunable, use this command:
# These power savings options may impact the performance of some applications.

echo 1 > /sys/devices/system/cpu/sched_mc_power_savings

# The VM subsystem, in the Linux kernel, buffers writes to files that applications perform for a period of time. This caching allows the kernel to group consecutive writes into one big write, and to generally optimize the disk IO to be the most efficient. The kernel, by default, will start writing out data to disk after 5 seconds, so, if a power failure or kernel crash happens, at most, 5 seconds of data would be lost.
#
#
# If your machine has a reliable power supply (for example because you have a UPS or because your laptop has a battery) and doesn't crash much, you can increase this time so that the VM subsystem can do a better job optimizing the IO, as well as having the disk (and the SATA link when using ALPM) in lower power states for a longer period of time.
#
# To increase the timeout to 15 seconds, you can issue this command:

echo 60000 > /proc/sys/vm/dirty_writeback_centisecs

# For several years, the Linux kernel has had a "laptop mode" for the IO subsystem. When laptop mode is enabled, the kernel will try to be smart about when to do IO, to give the disk and the SATA links as much time as possible in a low power state.
#
# To enable laptop mode, you can use this command:
# Several distributions also include the laptopmode scripts as part of their standard installation. These scripts enable laptop mode automatically, in some cases.

echo 5 > /proc/sys/vm/laptop_mode

# hal is a core component of the various desktop environments and deals with all sorts of hardware interaction. One component of the hal daemon is the part where it polls the cdrom drive regularly (as often as once every two seconds!) to see if the user has inserted a CD. This is used, for example, to automatically open a new window with a file browser for the CD.
#
#
# Such regular polling will keep the hardware awake somewhat; the amount of power consumed depends on the exact type of CDROM drive. It also depends on the presence of the ALPM feature.
#
#
# If you rarely or never insert CDs (for example because the machine in question is a server located 3000 miles away), you can save some power by stopping this polling.
#
#
# Current versions of hal have a special command for this:

hal-disable-polling --device /dev/cdrom
# Note that this means that you will not get a pop-up window if you insert a CD. To enable this polling again, use the this command:
#
# hal-disable-polling --device /dev/scd0 --enable-polling

#Most ethernet controllers have a feature called "Wake On Lan" (WOL). WOL allows #the administrator to send the computer, when it's turned off, a magic packet o#ver ethernet that then powers the computer on.

#WOL is a great feature if you regularly power up computers remotely. However, WO#L also keeps the network card active, even when the computer is powered off.

# The current generation onboard audio (often called "High Definition" or HDA) has power savings capabilities similar to AC97. The Linux ALSA drivers support these capabilities, as of version 1.0.15 of the ALSA subsystem. These are scheduled to appear in the 2.6.24 kernel.
#
#
# Unlike the AC97 power saving mode, the HDA power saving mode is enabled by default.
#
#
# If you are running an older kernel, you can download the ALSA sound drivers from the ALSA website.

# To see if power save is enabled for the HDA controllers, you can use this command:
#
# # cat /sys/module/snd_hda_intel/parameters/power_save
# 10
#
# Power saving is enabled if the value that this shows is greater than zero.

#
# Disable it by replacing min_power with max_performance.

Save power with Ubuntu 9.04 (Jaunty Jackalope) on a ThinkPad T400

2009-04-20T16:14:46Z

Manuel:

Hi

'''Basic information:'''

I have Thinkpad T400 WC8......

9 cell battery now 60% last 4.37 h

Idle consumtion after this tipps: 11-13 watts

I use the ATI Card with the fglrx drivers, unfortunatelly the have no option to save power.

I use powernowd, Gudiance Power manager and KDE4.2 powerdevil.

I will get into deeper later.

'''Let's start:'''

Set wlan and bluetooth off (hardware switch)

'''My Bios Settings:'''

Bluetooth off
Modem off
//have to look up other things//

'''Script to save power'''

Save this script as /etc/rc.local

Then modify /etc/kde4/kdm/Xsetup

and add:

exec /etc/rc.local

before exit 0

The script:

#!/bin/bash
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

#exit 0

## From lesswatts.org
#
# Zusammenstellung von Befehlen die man nach dem booten aktivieren muss
# auch von Powertop usw
#
# Modem und Bluetooth in Bios abschalten
#
#

# The sched_mc_power_savings tunable can save a significant amount of power (multiple Watts) under workloads where there is idle time in the system. To enable the tunable, use this command:
# These power savings options may impact the performance of some applications.

echo 1 > /sys/devices/system/cpu/sched_mc_power_savings

# The VM subsystem, in the Linux kernel, buffers writes to files that applications perform for a period of time. This caching allows the kernel to group consecutive writes into one big write, and to generally optimize the disk IO to be the most efficient. The kernel, by default, will start writing out data to disk after 5 seconds, so, if a power failure or kernel crash happens, at most, 5 seconds of data would be lost.
#
#
# If your machine has a reliable power supply (for example because you have a UPS or because your laptop has a battery) and doesn't crash much, you can increase this time so that the VM subsystem can do a better job optimizing the IO, as well as having the disk (and the SATA link when using ALPM) in lower power states for a longer period of time.
#
# To increase the timeout to 15 seconds, you can issue this command:

echo 60000 > /proc/sys/vm/dirty_writeback_centisecs

# For several years, the Linux kernel has had a "laptop mode" for the IO subsystem. When laptop mode is enabled, the kernel will try to be smart about when to do IO, to give the disk and the SATA links as much time as possible in a low power state.
#
# To enable laptop mode, you can use this command:
# Several distributions also include the laptopmode scripts as part of their standard installation. These scripts enable laptop mode automatically, in some cases.

echo 5 > /proc/sys/vm/laptop_mode

# hal is a core component of the various desktop environments and deals with all sorts of hardware interaction. One component of the hal daemon is the part where it polls the cdrom drive regularly (as often as once every two seconds!) to see if the user has inserted a CD. This is used, for example, to automatically open a new window with a file browser for the CD.
#
#
# Such regular polling will keep the hardware awake somewhat; the amount of power consumed depends on the exact type of CDROM drive. It also depends on the presence of the ALPM feature.
#
#
# If you rarely or never insert CDs (for example because the machine in question is a server located 3000 miles away), you can save some power by stopping this polling.
#
#
# Current versions of hal have a special command for this:

hal-disable-polling --device /dev/cdrom
# Note that this means that you will not get a pop-up window if you insert a CD. To enable this polling again, use the this command:
#
# hal-disable-polling --device /dev/scd0 --enable-polling

#Most ethernet controllers have a feature called "Wake On Lan" (WOL). WOL allows #the administrator to send the computer, when it's turned off, a magic packet o#ver ethernet that then powers the computer on.

#WOL is a great feature if you regularly power up computers remotely. However, WO#L also keeps the network card active, even when the computer is powered off.

ethtool -s eth0 wol d
# d:g g to enable Battery charge control features

# To set the thresholds for starting and stopping battery charging (in percent of current full charge capacity):
#
# # echo 40 > /sys/devices/platform/smapi/BAT0/start_charge_thresh
# # echo 70 > /sys/devices/platform/smapi/BAT0/stop_charge_thresh
# # cat /sys/devices/platform/smapi/BAT0/*_charge_thresh
#

#echo 23 > /sys/devices/platform/smapi/BAT0/start_charge_thresh
#echo 92 > /sys/devices/platform/smapi/BAT0/stop_charge_thresh

# Hint:
# Battery charging thresholds can be used to keep Li-Ion ad Li-Polymer batteries partially charged, in order to increase their lifetime.
#
# To prevent charging for 17 minutes (regardless of thresholds):
#
# # 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 using an Ultrabay battery.
#
# To cancel charging preventation:
#
# # echo 0 > /sys/devices/platform/smapi/BAT0/inhibit_charge_minutes
#
# To force battery discharging (even if connected to AC):
#
# # echo 1 > /sys/devices/platform/smapi/BAT0/force_discharge
#
# Hint:
# This can be used to choose which battery is discharged when using an UltraBay battery.
#
# To cancel forced discharge:
#
# # echo 0 > /sys/devices/platform/smapi/BAT0/force_discharge
