Installing Ubuntu 7.10 (Gutsy Gibbon) on a ThinkPad T61

2007-09-28T13:47:00Z

Yaemmanuelli: /* Fingerprint Reader */

==Installation Notes ==

If booting with the default options gives you a blank screen you should select the "Safe Graphics" menu choice when booting from the live CD.

If you are doing a text mode install such as PXE/network then your screen will be corrupted during the process. Workaround and details
are at https://bugs.launchpad.net/ubuntu/+source/xresprobe/+bug/127008

== Display/Video ==

=== Accelerated Video and Desktop Effects ===
'''Intel''' 2D and 3D accelerated video work out of the box.

As of September 19, compiz is disabled on the intel video cards. To fix edit /usr/bin/compiz and around line 46 comment this portion out:

<nowiki>#T="$T 8086:2982 8086:2992 8086:29a2 8086:2a02 8086:2a12" # intel 965</nowiki>

This edit will need to be reapplied every time compiz is updated. A more permanent method is create a script named compiz.sh with the following in it:
#!/bin/sh
SKIP_CHECKS=yes compiz --replace
Then, make it executable by right-clicking the file, selecting Properties, then selecting Permissions, and checking Allow executing file as program.

Double-click on the script and select Run to start compiz. To have it start at boot, go to System -> Preferences -> Sessions. Click Add, name it something, and for Command, browse to and choose the compiz.sh you created. Click Ok and Close.

'''Nvidia''' 2D video works out of the box, to enable accelerated 3D support click System->Administration->Restricted Drivers Manager

===Installing Nvidia drivers manually===

{{WARN| Installing the drivers via Synaptic or the Restricted Drivers Manager are the only supported methods of installing the Nvidia driver, the method below (while it works for most people) is not supported}}

Download the drivers from http://www.nvidia.com/object/linux_display_ia32_100.14.19.html and save it to your Desktop.
Exit to a virtual terminal by pressing [CTRL]+[ALT]+[F2]

Stop the X server:

$ sudo /etc/init.d/gdm stop (stopping the X server)

Remove nvidia-glx-new

$ sudo apt-get remove nvidia-glx-new

Install the drivers:

$ sh NVIDIA-Linux-x86-100.14.19-pkg1.run (depending on the version that will be online)

Follow instructions in the installer, when complete restart the X-Server with:

$ sudo /etc/init.d/gdm restart (restarting the X server)

{{NOTE| If you have an issue with Gnome or KDE crashing please see [https://bugs.launchpad.net/bugs/98641 this bug report] or search the ubuntuforums for some solutions}}

===Multiple Monitors===

'''Nvidia N140m:'''

When using the default drivers (The open source "nv" drivers) you can use Administration->"Screens and Graphics" to setup the second monitor

Using the proprietary drivers you must use the Nvidia tool located at Applications->System Tools-> Nvidia X Server Settings.

It has been reported that the NVIDIA drivers tend to crash with xinerama enabled. 2 displays with xinerama off has been stable.

'''Intel X3100:'''

Plugging in an external monitor works, but is a clone of the built-in LCD by default. Following the instructions on [http://www.thinkwiki.org/wiki/Intel_Graphics_Media_Accelerator_X3100 this page] to extend your desktop to the second monitor does *not* work; it results in the crash described [http://lists.freedesktop.org/archives/xorg/2007-April/023326.html here]. According to [http://lists.freedesktop.org/archives/xorg/2007-April/023335.html this post] and [https://bugs.freedesktop.org/show_bug.cgi?id=10706 this bug report], the problem is a new Xinerama implementation and an old config file.

To extend your desktop to the second monitor, you'll want to do what [http://wiki.debian.org/XStrikeForce/ReleaseNotes this page] suggests (under "Dual-Head config breakage with xserver-xorg-video-intel").

Below is an example for a 1680x1050 built-in LCD and a 1600x1200 external LCD:
Add a "Virtual 3280 1200" line in the Display SubSection of the Screen Section in your xorg.conf:
{{Fixme|If someone could include an example of the change described above it would be greatly appreciated}}
Exit to a virtual terminal (press: ctrl-alt-F1), login and type the following:

{{cmdroot|sudo /etc/init.d/gdm stop}}

{{cmdroot|xrandr --output LVDS --auto}}

To set the built-in LCD to ouput 1680x1050

{{cmdroot|xrandr --output VGA --right-of LVDS}}

To extend the desktop

=== Fonts on High-Res Screens ===

On high-res screens (e.g. 15" 1680x1050), the default fonts are too big ([https://bugs.launchpad.net/ubuntu/+source/gdm/+bug/99145 Launchpad bug report]). You can fix this by following these steps:

# Open System->Preferences->Appearance
# Select the "Fonts" tab
# Click the "Details" button (lower right)
# Adjust the Resolution down to 96dpi
# Make sure you have Subpixel (LCD) Smoothing enabled
# Save the preferences

If you also want small fonts on the GDM login window, you can do this:

# Open System->Administration->Login Window
# Select the 'Security' tab
# Click the 'Configure X-Server' button
# Append '-dpi 96' (without quotes) to the text in the 'Command' field
# Reboot the computer.

=== Brightness ===
====Intel X3100:====
The brightness controls do not work out of the box, but they should work once you apply all of the system updates.

However, there now appears to be a bug where the brightness controls stop working after you resume from a suspend.

Until the brightness bugs are finally worked out, you can install "xbacklight" (Applications -> Accessories -> Terminal, type "sudo apt-get install xbacklight" without the quotation marks and hit enter), which allows you to set the brightness from the command line and provides a greater range of brightness values.

To set brightness, go back to the terminal and type "xbacklight =VALUE" where VALUE is a number from 0 to 100 for how bright you want your display to be.

=====Creating brightness shortcuts=====
If you don't want to use the terminal you can set up shortcuts to pre-defined brightness levels:

1) Right-click on the desktop and select Create Launcher...

2) Make it look like this:<br>
[[Image:XBacklight launcher 50.png]]<br>
The 50 means that the backlight will be at 50% brightness. If you want your shortcut to set the brightness to 100% then simply replace 50 with 100 when you create your launcher (Shortcuts in Windows are analogous to Launchers in Ubuntu). Many people use at least two brightness levels (for example, 100% when on AC power, 50% when on battery power) so it's a good idea to make a launcher for each commonly used brightness level. I also suggest adding them to the upper panel (Linux for menu bar) so that they're easily accessible. If you want, you can use your own custom icons by right-clicking the launcher, selecting Properties, and then clicking on the picture in the Properties window and browsing for your own.

====Nvidia Quadro N140:====
The brightness controls do not work, however you can switch to a virtual terminal (ctrl+alt+F1) increase or decrease the brightness and then switch back to X (ctrl+alt+F7) without disrupting the running applications

====NVIDIA Quadro 570M:====
Brightness controls do not work out of the box. As in the N140 case, changing brightness in tty1, then switching back does work.

== Audio ==

Audio should work out of the box on a fresh Beta install.

Microphone may not work with applications (like sound recorder and skype) even though sound can be heard through the speakers or headphones.

===Enabling Sound and Fixing the Volume Controls===

By default, the sound may be disabled and the volume control buttons on the laptop (up by the ThinkVantage button) and the volume control applet (up by the clock) will not control the speaker volume (they actually control the microphone!). https://bugs.launchpad.net/ubuntu/+bug/136287
this bug report links to a fixed version from an Ubuntu dev a fixed version is available
To fix this:

# Right-click on the volume control applet (by the clock) and select "Open Volume Control"
# In the "Switches" tab, make sure "Headphone" and "Speaker" are both checked.
# Close the Volume control.
# Right-click on the volume control applet again and select "Preferences".
# Make sure the device is set to "HDA Intel (Alsa mixer)" and highlight the "PCM" option.
# Close the preferences.
# Select System->Preferences->Sound.
# In the "Default Mixer Tracks" section, make sure "PCM" is highlighted.
# Close the sound preferences.

You should now hear sound and be able to control the volume using the laptop buttons or volume applet.

== Intel Wireless ==

Intel 4965 users will find that they have a very unstable connection with random disconnects within 30 to 60 minutes of association. Once a system update is performed an updated package of wpa_supplicant will resolve this issue.

== Modem ==

The modem works with the Linuxant drivers available at http://www.linuxant.com

==Bluetooth==

To enable bluetooth you must have the thinkpad-acpi modules loaded:

{{cmdroot|sudo modprobe thinkpad-acpi}}

Then su to root (sudo doesn't work unless you put these commands into a script) to enable the root account so you can use su see [[http://ubuntuguide.org/wiki/Ubuntu:Feisty#How_to_set.2Fchange.2Fenable_root_user_password| This link]].

{{cmdroot|su }}

To enable bluetooth:

{{cmdroot|echo enable > /proc/acpi/ibm/bluetooth}}

To disable bluetooth:

{{cmdroot|echo disable > /proc/acpi/ibm/bluetooth}}

If you would like to set the keybindings put those commands into scripts such as:

{{cmdroot|sudo gedit /usr/bin/enablebt}}

Enter the following:
echo enable > /proc/acpi/ibm/bluetooth

Close/Save the file and mark it executable
{{cmdroot|sudo chmod +x /usr/bin/enablebt}}

{{cmdroot|sudo gedit /usr/bin/disablebt}}

enter the following

echo disable > /proc/acpi/ibm/bluetooth
Close/Save the file and mark it executable
{{cmdroot|sudo chmod +x /usr/bin/disablebt}}

Modify sudoers to permit those scripts to run as root (Possible security risk)

{{cmdroot|sudo visudo}}

Enter the following under the section "# User privilege specification" replacing enter_your_username_here with your username

enter_your_username_here ALL= NOPASSWD: /usr/bin/enablebt
enter_your_username_here ALL= NOPASSWD: /usr/bin/disablebt

Note: I need to lookup the keycodes to create the shortcuts, so this section is a work in progress.

: A comment - I've tried finding the keycode using all the methods mentioned here [https://wiki.ubuntu.com/LaptopTestingTeam/HotkeyResearch] but the three methods "keyboard shortcuts", "showkey" and "tail" give me nothing. Fn-F8 does produce an acpi event, maybe that would be a good alternative. "ibm/hotkey HKEY 00000080 00001008". On my computer that's already set-up to run the script /etc/acpi/thinkpad-stretchortouchpad.sh. So I might just turn that into a bluetooth trigger instead as I have no interest in turning keys into a number-pad (which I think is what thinkpad-stretchortouchpad.sh tries to do, but fails on my system).

== Fingerprint Reader ==

The reader works with ThinkFinger. General instructions available [http://www.thinkwiki.org/wiki/Integrated_Fingerprint_Reader here] and [https://wiki.ubuntu.com/ThinkFinger here].

Debian packages for i386 can be found at: http://www.rubixlinux.org/debian/thinkfinger/

If you prefer using apt-get, you can add thinkfinger package repository for gutsy by creating /etc/apt/sources.list.d/thinkfinger.list with these two lines:

deb http://ppa.launchpad.net/jldugger/ubuntu gutsy main restricted universe multiverse
deb-src http://ppa.launchpad.net/jldugger/ubuntu gutsy main restricted universe multiverse

Then update a package database and install packages:

sudo apt-get update
sudo apt-get install libpam-thinkfinger libthinkfinger-dev libthinkfinger-doc libthinkfinger0 thinkfinger-tools

After the package is installed add the following two lines to /etc/pam.d/common-auth

auth sufficient pam_thinkfinger.so
auth required pam_unix.so try_first_pass

Note: Instructions in French available at http://doc.ubuntu-fr.org/materiel/thinkfinger

* Recording fingerprints works
* Login works
* The password must be entered to unlock a locked screensaver
* sudo works
* gksu and gksudo hang : for example it is necessary to run synaptic twice and enter your password upon failure. To be able to use the Finger print reader in the session subsequently, kill the hanging gksu/gksudo process. A workaround is editing the Gnome System Menu (alacarte) to specify sudo instead of gksu/gksudo for the launching command and choose type "Application in Terminal" : this opens an extra terminal window for each superuser application you want to use though.
{{HELP|Today 14th of September 2007, after Gutsy's updates, Fingerprint is no longer prompted for login and sudo. Looks like a PAM problem. sudo tf-tools --acquire still works
Today 17th of September.. this issue is solved after updates..
19th of September.. this issue is back after updates
UPDATE 27 Sept. 2007: Problem is probably caused by fact that version 0.2.3 and higher requires support of uinput in the kernel. See FAQ section on [https://wiki.ubuntu.com/ThinkFinger this page].

To make it work, load module by
sudo modprobe uinput
and make sure that it will be loaded on boot by adding "uinput" (without quotes) line to /etc/modules. After that sudo should work, as well as login to console and by gdm.
28 Sept 2007: the above hint works on my T61. Thanks!
}}

== Trackpad scrolling ==

Trackpad scrolling works out of the box in the standard thinkpad way: Slide your finger up and down the very right edge of the trackpad.

To enable using the middle mouse button to scroll, add the following lines to the "Configured Mouse" section in
{{path|/etc/X11/xorg.conf}}:

Option "EmulateWheel" "true"
Option "EmulateWheelButton" "2"

== Hibernate/Suspend ==

=== Blank Screen Fix ===

You may get a blank screen when resuming from suspend or hibernate ([https://bugs.launchpad.net/ubuntu/+bug/134391 Launchpad bug report]). If so, try editing {{path|/boot/grub/menu.lst}}, adding "acpi_sleep=s3_bios" (no quotes) to the "defoptions" list so that it looks something like this:

## additional options to use with the default boot option, but not with the
## alternatives
## e.g. defoptions=vga=791 resume=/dev/hda5
# defoptions=quiet splash '''acpi_sleep=s3_bios'''

Once you have edited the line and added the acpi_sleep parameter, you need to run

$ sudo update-grub

Note that if you get the blank screen upon resume, a quick-fix is to switch to a console (Ctrl-Alt-F1) and then back to X (Ctrl-Alt-F7). This will usually bring the display back to life. However, the long-term fix is to add the acpi_sleep parameter as shown above.

== Items that work out of the box ==

'''Intel Video:''' 2D and 3D acceleration works

'''Nvidia:''' 2D works, 3D requires the installation of the proprietary drivers

'''Wireless:''' Atheros cards work. Intel cards work properly after full updates.

'''Network Card'''

'''Firewire'''

'''Wireless switch'''

'''4-in-1 card reader'''

'''Headphones'''

'''Keyboard Shortcuts:'''

* Fn-PgUp activates/deactivates the thinklight
* Fn-Up will trigger stop on a media player
* Fn-Down will toggle pause and play on a media player
* Fn-Left/Right go to prev/next tracks on a media player
* Fn-F2 properly locks the screen
* Fn-F3 shows remaining battery
* Fn-F4 suspends (to ram)
* Fn-F12 hibernates (to disk)
* PrtSc opens the screenshot dialog

'''Docking Stations:'''

All docking station models should work and the following features have been tested:

* DVI or Analog video: You can switch to it using "Administration->Screens and Graphics", if you are using the proprietary Nvidia drivers you must use the Nvidia Control Panel.

* Network Pass-through

* Modem Pass-through

* USB ports: Connected upon docking

* PS/2 Ports

== Items that don't work ==

* Wireless USB/UWB - https://bugs.launchpad.net/ubuntu/+bug/136287
* USB ports can end up temporarily disabled - https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/126369

== Power consumption ==

Gutsy is the first version of Ubuntu to feature a tickless kernel (i386 only, not in AMD64 yet). Power consumption
can be monitored using the powertop tool under Ubuntu and using Lenovo battery monitor
under Windows.

$ sudo apt-get install powertop
$ sudo powertop

I couldn't find any difference in power consumption between the i386 tickless kernel (even with 70ms average sleep in C4)
and AMD64 kernel (2ms average sleep in C4). It would be expected that considerably less power would be consumed for the
i386 tickless kernel.

There is also a graph available by Right-clicking on the battery icon and selecting Power History.

These are the figures measured on a T61 15.4" 1680x1050 screen 7300 processor (2GHz) 2GB RAM, Intel X3100 graphics
with 4965 wifi, Bluetooth and UWB.

{| border=1 cellpadding=5

| Gutsy, all radios on, 100% brightness
|-
| 14.2W
| Gutsy, all radios on, 10% brightness

Adding the Nvidia card increases the laptops power requirements.

These are the figures measured on a T61 14" 1440x900 screen 2.2ghz Core2Duo 2GB RAM, Nvidia 140m video, IWL4965 wifi and Bluetooth (Disabled):

Yaemmanuelli: /* Fingerprint Reader */

==Installation Notes ==

If booting with the default options gives you a blank screen you should select the "Safe Graphics" menu choice when booting from the live CD.

If you are doing a text mode install such as PXE/network then your screen will be corrupted during the process. Workaround and details
are at https://bugs.launchpad.net/ubuntu/+source/xresprobe/+bug/127008

== Display/Video ==

'''Intel''' video works out of the box, but '''Nvidia''' accelerated 3D support is not installed by default. To install Nvidia 3D support click System->Administration->Restricted Drivers Manager

{{WARN| Installing the drivers via Synaptic or the Restricted Drivers Manager are the only supported methods of installing the Nvidia driver, the method below (while it works for most people) is not supported}}

If the above does not work you can install the drivers manually by going to the NVIDIA website [http://www.nvidia.com/object/unix.html http://www.nvidia.com/object/unix.html] and download your 32 bit or 64 bit driver and install it manually, for 64 bit that is:
# [CTRL]+[ALT]+[F2]
# $ sudo /etc/init.d/gdm stop (stopping the X server)
# $ sh NVIDIA-Linux-x86_64-100.14.11-pkg2.run (depending on the version that will be online)
# follow instructions in the installer
# $ sudo /etc/init.d/gdm restart (restarting the X server)

{{NOTE| If you have an issue with Gnome or KDE crashing please see [https://bugs.launchpad.net/bugs/98641 this bug report] or search the ubuntuforums for some solutions}}

{{NOTE|Desktop Effects may be unstable with the proprietary driver, Nvidia is aware of the issue and claims that the next release will resolve the issue. If, for example, you notice the screensaver or glxgears is crashing X, go to System -> Preferences -> Appearance -> Desktop effects and turn desktop effects off. }}

NOTE: As of September 19, compiz breaks on the intel video cards. To fix kwrite /usr/bin/compiz edit line 46, and comment this portion out:

#T="$T 8086:2982 8086:2992 8086:29a2 8086:2a02 8086:2a12" # intel 965

Control + Alt + Delete to restart X. Should be working.

===Multiple Monitors===

Nvidia N140m:

When using the default drivers (The open source "nv" drivers) you can use Administration->"Screens and Graphics" to setup the second monitor

Using the proprietary drivers you must use the Nvidia tool located at Applications->System Tools-> Nvidia X Server Settings

Intel X3100:

Plugging in an external monitor works, but is a clone of the built-in LCD by default. Following the instructions on [http://www.thinkwiki.org/wiki/Intel_Graphics_Media_Accelerator_X3100 this page] to extend your desktop to the second monitor does *not* work; it results in the crash described [http://lists.freedesktop.org/archives/xorg/2007-April/023326.html here]. According to [http://lists.freedesktop.org/archives/xorg/2007-April/023335.html this post] and [https://bugs.freedesktop.org/show_bug.cgi?id=10706 this bug report], the problem is a new Xinerama implementation and an old config file.

To extend your desktop to the second monitor, you'll want to do what [http://wiki.debian.org/XStrikeForce/ReleaseNotes this page] suggests (under "Dual-Head config breakage with xserver-xorg-video-intel").

In my case, I have a 1680x1050 built-in LCD and a 1600x1200 external LCD, so I

# added a "Virtual 3280 1200" line in the Display SubSection of the Screen Section in my xorg.conf
# restarted X
# ran "xrandr --output LVDS --auto" to get my built-in LCD to ouput 1680x1050
# ran "xrandr --output VGA --right-of LVDS" to extend my desktop

=== Fonts on High-Res Screens ===

On high-res screens (e.g. 15" 1680x1050), the default fonts are too big ([https://bugs.launchpad.net/ubuntu/+source/gdm/+bug/99145 Launchpad bug report]). You can fix this by following these steps:

# Open System->Preferences->Appearance
# Select the "Fonts" tab
# Click the "Details" button (lower right)
# Adjust the Resolution down to 96dpi
# Make sure you have Subpixel (LCD) Smoothing enabled
# Save the preferences

If you also want small fonts on the GDM login window, you can do this:

# Open System->Administration->Login Window
# Select the 'Security' tab
# Click the 'Configure X-Server' button
# Append '-dpi 96' (without quotes) to the text in the 'Command' field
# Reboot the computer.

=== Brightness ===
====Intel X3100:====
The brightness controls do work not out of the box, but they should work once you apply all of the system updates.

However, there now appears to be a bug where the brightness controls stop working after you resume from a suspend.

Until the brightness bugs are finally worked out, you can install "xbacklight" (apt-get install xbacklight), which allows you to set the brightness from the command line and provides a greater range of brightness values.

====Nvidia Quadro N140:====
The brightness controls do not work, however you can switch to a virtual terminal (ctrl+alt+F1) increase or decrease the brightness and then switch back to X (ctrl+alt+F7) without disrupting the running applications

== Audio ==

Audio does not work out of the box, but will work once you apply all the updates.

Microphone may not work with applications (like sound recorder and skype) even though sound can be heard through the speakers or headphones.

===Enabling Sound and Fixing the Volume Controls===

# In the "Switches" tab, make sure "Headphone" and "Speaker" are both checked.
# Close the Volume control.
# Right-click on the volume control applet again and select "Preferences".
# Make sure the device is set to "HDA Intel (Alsa mixer)" and highlight the "PCM" option.
# Close the preferences.
# Select System->Preferences->Sound.
# In the "Default Mixer Tracks" section, make sure "PCM" is highlighted.
# Close the sound preferences.

You should now hear sound and be able to control the volume using the laptop buttons or volume applet.

== Intel Wireless ==

Intel 4965 users will find that they have a very unstable connection with random disconnects within 30 to 60 minutes of association. The issue is described in [https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/138873 this] bug report. The problem is with wpa_Supplicant and Kees Cook (An Ubuntu Developer) has posted a fixed version [http://ppa.launchpad.net/keescook/ubuntu/pool/main/w/wpasupplicant/ here]. The fix should be available via a normal update soon.

== Modem ==

The modem works with the Linuxant drivers available at http://www.linuxant.com

==Bluetooth==

To enable bluetooth you must have the thinkpad-acpi modules loaded:

{{cmdroot|sudo modprobe thinkpad-acpi}}

Then su to root (sudo doesn't work unless you put these commands into a script) to enable the root account so you can use su see [[http://ubuntuguide.org/wiki/Ubuntu:Feisty#How_to_set.2Fchange.2Fenable_root_user_password| This link]].

{{cmdroot|su }}

To enable bluetooth:

{{cmdroot|echo enable > /proc/acpi/ibm/bluetooth}}

To disable bluetooth:

{{cmdroot|echo disable > /proc/acpi/ibm/bluetooth}}

== Fingerprint Reader ==

CRITICAL ERROR: Use the mac80211 iwl3945 driver instead. ipw3945d is closed source sometimes hangs on resume.

The iwl3945 driver generally only works for about 30 minutes to an hour due to a bug with wpa_supplicant see the section above on the IWL4965 for instructions on fixing this issue

== Items that work out of the box ==

'''Intel Video:''' 2D and 3D acceleration works

'''Nvidia:''' 2D works, 3D requires the installation of the proprietary drivers

'''Wireless:''' Atheros cards work, see [http://www.thinkwiki.org/index.php?title=Installing_Ubuntu_7.10_%28Gutsy_Gibbon%29_Tribe_5_on_a_ThinkPad_T61&action=edit&section=8 this] section for a note regarding Intel cards

* PrtSc opens the screenshot dialog

'''Docking Stations:'''

All docking station models should work and the following features have been tested:

* DVI or Analog video: You can switch to it using "Administration->Screens and Graphics", if you are using the proprietary Nvidia drivers you must use the Nvidia Control Panel.

* Network Pass-through

* Modem Pass-through

* USB ports: Connected upon docking

* PS/2 Ports

== Items that don't work ==

* Wireless USB/UWB - https://bugs.launchpad.net/ubuntu/+bug/136287
* USB ports can end up temporarily disabled - https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/126369

== Power consumption ==

Gutsy is the first version of Ubuntu to feature a tickless kernel (i386 only, not in AMD64 yet). Power consumption
can be monitored using the powertop tool under Ubuntu and using Lenovo battery monitor
under Windows.

$ sudo apt-get install powertop
$ sudo powertop

I couldn't find any difference in power consumption between the i386 tickless kernel (even with 70ms average sleep in C4)
and AMD64 kernel (2ms average sleep in C4). It would be expected that considerably less power would be consumed for the
i386 tickless kernel.

There is also a graph available by Right-clicking on the battery icon and selecting Power History.

These are the figures measured on a T61 15.4" 1680x1050 screen 7300 processor (2GHz) 2GB RAM, Intel X3100 graphics
with 4965 wifi, Bluetooth and UWB.

=== Linux X.Org driver ===
Supported by Xorg [http://www.x.org/wiki/IntelGraphicsDriver?highlight=%28intel%29%7C%28driver%29]. The driver supports hardware accelerated 3D via the Direct Rendering Infrastructure (DRI), but only in depths 16 and 24.

Version 2.1.1 of the driver fixes a TV output problem. Use xrandr to view the enabled screens in X.

=== Linux Intel driver ===
There is a Graphics driver for the Mobile Intel 965 Express Chipset Family at [http://downloadfinder.intel.com/scripts-df-external/filter_results.aspx?strTypes=all&ProductID=2301&OSFullName=Linux*&lang=eng&strOSs=39&submit=Go%21 Intels Support Site]. This driver is just a snapshot of the Xorg/XFree86 driver.

==== ThinkPad LCD ====
Display on the internal LCD works as long as you set the monitor settings correct.

==== External VGA port ====
Works. Dualhead is supported.

There are two options for running the external VGA port - either as a copy of the LCD (clone) or as a separate workspace. Here is an example for the separate workspace mode for xorg.conf for the X60s:

Installing Ubuntu 7.10 (Gutsy Gibbon) on a ThinkPad T61

Yaemmanuelli: /* Fingerprint Reader */

==Installation Notes ==

If you have an nVidia graphics chipset, you may need to boot from the Gutsy installation media using the "Safe Graphics" menu choice. My attempts to boot with the default choice left me with a blank screen. After installation, I [http://www.albertomilone.com/nvidia_scripts1.html installed Envy] and followed the [http://albertomilone.com/wordpress/?p=107 using Envy on Gutsy instructions] to install the nVidia driver, and it "just worked".
:--[[User:Brianfinley|Brian E. Finley]] 18:18, 2 September 2007 (UTC)

== Video ==

'''Intel''' video works out of the box, but '''Nvidia''' accelerated 3D support is not installed by default. To install Nvidia 3D support click System->Administration->Restricted Drivers Manager

With Nvidia, you may experience a bug where the X server crashes or fails to start. Numerous solutions are provided (with mixed results) in the [https://bugs.launchpad.net/bugs/98641 Launchpad bug report] as well as [http://ubuntuforums.org/showthread.php?t=533557&highlight=Thinkpad+T61 this thread] on the Ubuntu forums.

== Audio ==

Audio does not work out of the box, but will work once you apply all the updates.

===Enabling Sound and Fixing the Volume Controls===

By default, the sound may be disabled and the volume control buttons on the laptop (up by the ThinkVantage button) and the volume control applet (up by the clock) will not control the speaker volume. To fix this:

# Right-click on the volume control applet (by the clock) and select "Open Volume Control"
# In the "Switches" tab, make sure "Headphone" and "Speaker" are both checked.
# Close the Volume control.
# Right-click on the volume control applet again and select "Preferences".
# Make sure the device is set to "HDA Intel (Alsa mixer)" and highlight the "PCM" option.
# Close the preferences.
# Select System->Preferences->Sound.
# In the "Default Mixer Tracks" section, make sure "PCM" is highlighted.
# Close the sound preferences.

You should now hear sound and be able to control the volume using the laptop buttons or volume applet.

{{HELP|Is this still necessary after updating? I did not seem to require this change.}}

2007/09/03 - This was needed for me, at least partially : after applying updates, I could hear sound, but the volume control button near the ThinkVantage button did not do anything, and it worked after I followed the intructions above (Yves-Antoine Emmanuelli, Paris.

== Modem ==

The modem works with the Linuxant drivers available at http://www.linuxant.com

== Fingerprint Reader ==

The reader works with ThinkFinger. [http://www.thinkwiki.org/wiki/Integrated_Fingerprint_Reader Instructions].

-----------------------------------------
2007/09/04 : Install of Debian packages for i386 found on http://www.rubixlinux.org/debian/thinkfinger/ went fine.

Replaced the contents /etc/pam.d/common-auth by the following two lines :

auth sufficient pam_thinkfinger.so<br>
auth required pam_unix.so try_first_pass

as instructed on http://doc.ubuntu-fr.org/materiel/thinkfinger

Recording my fingerprint went fine<br>
Login works OK<br>
But gksudo crashes : for example it is necessary to run synaptic twice, and finally enter password.

2007/09/04 : End
------------------------------------------

== Trackpad scrolling ==

Trackpad scrolling works out of the box in the standard thinkpad way: Slide your finger up and down the very right edge of the trackpad.

To enable using the middle mouse button to scroll, add the following lines to the "Configured Mouse" section in
{{path|/etc/X11/xorg.conf}}:

Option "EmulateWheel" "true"
Option "EmulateWheelButton" "2"

== Hibernate/Suspend ==

You may get a blank screen when resuming from suspend or hibernate ([https://bugs.launchpad.net/ubuntu/+bug/134391 Launchpad bug report]). If so, try editing {{path|/boot/grub/menu.lst}}, adding "acpi_sleep=s3_bios" (no quotes) to the first kernel entry so that it looks something like this ('''do not copy and paste this code''', just append the acpi_sleep=s3_bios parameter as shown -- the UUID will not be the same from one system to the next):

title Ubuntu, kernel 2.6.22-10-generic
root (hd0,0)
kernel /boot/vmlinuz-2.6.22-10-generic root=UUID=[...] ro quiet splash '''acpi_sleep=s3_bios'''
initrd /boot/initrd.img-2.6.22-10-generic
quiet

Note that if you get the blank screen upon resume, a quick-fix is to switch to a console (Ctrl-Alt-F1) and then back to X (Ctrl-Alt-F7). This will usually bring the display back to life. However, the long-term fix is to add the acpi_sleep parameter as shown above.

== Fonts on High-Res Screens ==

On high-res screens (e.g. 15" 1680x1050), the default fonts are too big. You can fix this by following these steps:

# Open System->Preferences->Appearance
# Select the "Fonts" tab
# Click the "Details" button (lower right)
# Adjust the Resolution down to 96dpi
# Make sure you have Subpixel (LCD) Smoothing enabled
# Save the preferences

== Brightness ==

The brightness controls (Fn-Home, Fn-End) don't seem to work reliably (if at all), and the brightness dialog box occasionally will pop up at random or "stick" on the screen, often causing the screen to flicker. Messing around with the brightness controls (Fn-Home, Fn-End) will usually make the dialog to go away and the flickering stop. [https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/123854 Launchpad bug report].

With the Nvidia card to increase/decrease brightness hit Ctrl+Alt+F1 to drop to a virtual console, change the brightness and hit Ctrl-Alt-F7 to return to Gnome. This can be done without affecting running applications.

If you have an Intel card you can install the Gnome Brightness Applet to give you an easy way to change the brightness from within Gnome:

# Right-click on the top menu bar.
# Select "Add to Panel".
# Scroll down to the "System & Hardware" section.
# Highlight the "Brightness Applet" and click the "Add" button.

Using this applet often results in the "flickering screen syndrome" described above, but jiggling the brightness slider a little will cause this flickering to stop.

== Items that work out of the box ==

'''Intel Video:''' 2D and 3D acceleration works

'''Nvidia:''' 2D works, 3D requires the installation of the proprietary drivers

'''Wireless:''' Atheros and Intel work

* Fn-F2 properly locks the screen
* Fn-F3 shows remaining battery
* Fn-F4 suspends (to ram)
* Fn-F12 hibernates (to disk)
* PrtSc opens the screenshot dialog

'''Docking Stations:'''

All docking station models should work and the following features have been tested:

* DVI or Analog video: You can switch to it using xrandr for Intel cards or using the Nvidia Control Panel with the Nvidia card.

{{HELP|Does the new displayconfig-gtk tool work for switching video with the Intel card?}}

You should now hear sound and be able to control the volume using the laptop buttons or volume applet.

{{HELP|Is this still necessary after updating? I did not seem to require this change.}}

2007/09/03 - This was needed for me, at least partially : after applying updates, I could hear sound, but the volume control button near the ThinkVantage button did not do anything, and it worked after I followed the intructions above (Yves-Antoine Emmanuelli, Paris.

== Modem ==

The modem works with the Linuxant drivers available at http://www.linuxant.com

== Fingerprint Reader ==

The reader works with ThinkFinger. [http://www.thinkwiki.org/wiki/Integrated_Fingerprint_Reader Instructions].

== Trackpad scrolling ==

Trackpad scrolling works out of the box in the standard thinkpad way: Slide your finger up and down the very right edge of the trackpad.

To enable using the middle mouse button to scroll, add the following lines to the "Configured Mouse" section in
{{path|/etc/X11/xorg.conf}}:

Option "EmulateWheel" "true"
Option "EmulateWheelButton" "2"

== Hibernate/Suspend ==

You may get a blank screen when resuming from suspend or hibernate ([https://bugs.launchpad.net/ubuntu/+bug/134391 Launchpad bug report]). If so, try editing {{path|/boot/grub/menu.lst}}, adding "acpi_sleep=s3_bios" (no quotes) to the first kernel entry so that it looks something like this ('''do not copy and paste this code''', just append the acpi_sleep=s3_bios parameter as shown -- the UUID will not be the same from one system to the next):

title Ubuntu, kernel 2.6.22-10-generic
root (hd0,0)
kernel /boot/vmlinuz-2.6.22-10-generic root=UUID=[...] ro quiet splash '''acpi_sleep=s3_bios'''
initrd /boot/initrd.img-2.6.22-10-generic
quiet

Note that if you get the blank screen upon resume, a quick-fix is to switch to a console (Ctrl-Alt-F1) and then back to X (Ctrl-Alt-F7). This will usually bring the display back to life. However, the long-term fix is to add the acpi_sleep parameter as shown above.

== Fonts on High-Res Screens ==

On high-res screens (e.g. 15" 1680x1050), the default fonts are too big. You can fix this by following these steps:

# Open System->Preferences->Appearance
# Select the "Fonts" tab
# Click the "Details" button (lower right)
# Adjust the Resolution down until fonts look how you like them (96dpi is a common standard)
# Make sure you have Subpixel (LCD) Smoothing enabled
# Close the Details window and adjust the Application, Document, Desktop, etc fonts as desired (I set them all to 10).

== Brightness ==

The brightness controls (Fn-Home, Fn-End) don't seem to work reliably (if at all), and the brightness dialog box occasionally will pop up at random or "stick" on the screen, often causing the screen to flicker. Messing around with the brightness controls (Fn-Home, Fn-End) will usually make the dialog to go away and the flickering stop. [https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/123854 Launchpad bug report].

With the Nvidia card to increase/decrease brightness hit Ctrl+Alt+F1 to drop to a virtual console, change the brightness and hit Ctrl-Alt-F7 to return to Gnome. This can be done without affecting running applications.

If you have an Intel card you can install the Gnome Brightness Applet to give you an easy way to change the brightness from within Gnome:

# Right-click on the top menu bar.
# Select "Add to Panel".
# Scroll down to the "System & Hardware" section.
# Highlight the "Brightness Applet" and click the "Add" button.

Using this applet often results in the "flickering screen syndrome" described above, but jiggling the brightness slider a little will cause this flickering to stop.

== Items that work out of the box ==

'''Intel Video:''' 2D and 3D acceleration works

'''Nvidia:''' 2D works, 3D requires the installation of the proprietary drivers

'''Wireless:''' Atheros and Intel work

'''Network Card'''

'''Firewire'''

'''Wireless switch'''

'''4-in-1 card reader'''

'''Headphones/Microphone jacks'''

'''Bluetooth:''' The bluetooth module is detected but I have no bluetooth device to check with.

'''Keyboard Shortcuts:'''

* Fn-PgUp activates/deactivates the thinklight
* Fn-Up will trigger stop on a media player
* Fn-Down will toggle pause and play on a media player
* Fn-Left/Right go to prev/next tracks on a media player
* Fn-F2 properly locks the screen
* Fn-F3 shows remaining battery
* Fn-F4 suspends (to ram)
* Fn-F12 hibernates (to disk)
* PrtSc opens the screenshot dialog

'''Docking Stations:'''

All docking station models should work and the following features have been tested:

* DVI or Analog video: You can switch to it using xrandr for Intel cards or using the Nvidia Control Panel with the Nvidia card.

{{HELP|Does the new displayconfig-gtk tool work for switching video with the Intel card?}}

* Network Pass-through: Works

* Modem Pass-through: Works

* USB ports: Connected upon docking

* PS/2 Ports: Untested, may require a reboot.
