To enable 3D acceleration, the proprietary NVidia driver must be installed. The first time you boot into Ubuntu, you should get an alert asking if you want to install the binary driver. If not, it can be installed from the Hardware Drivers panel at System --> Administration --> Hardware Drivers.

If you want more options for configuring your video card than is provided by the Ubuntu control panels, you can install the NVidia Control Panel with

{{cmduser| sudo apt-get install nvidia-settings}}

which will add the NVidia X Server Settings panel to the Administration menu.

Alternately, more recent versions of the NVidia driver and Control Panel can be installed using EnvyNG (envyng-gtk in Synaptic). Simply start it up (System Tools --> EnvyNG) and ask it to install the NVidia driver. Using the most recent binary drivers, or at least ones more recent that
those installed by the Hardware Drivers panel, is required for proper Suspend functionality.

Unfortunately, there are some annoying bugs in the NVidia driver. The most annoying one is that after resuming from suspend, you will often get a blank white screen. To get past it, simply type in your password and press enter, and you will be returned to your desktop. Fortunately, Ubuntu has released a workaround for this bug, so it should go away once you update all your packages to the latest versions.

Another problem is that the driver does not report the correct refresh rate to Compiz, resulting in rough animation. To fix this, install the compizconfig-settings-manager package, then go to System --> Preferences --> Advanced Desktop Effects Settings. Click on General Options, go to the Display Settings tab, uncheck the Detect Refresh rate box and drag the Refresh Rate slider to 60. Also, check the Sync To VBlank box.

Next, Compiz animations are also choppy due to NVidia's PowerMizer feature, which slows down the GPU to conserve power when it is not in use. This works well for 3D games which constantly use 3D acceleration, but poorly for Compiz which uses the GPU in small bursts. To solve this problem, I made a couple of shell scripts which keep the GPU at its highest speed while running on AC power. The first one is named "powermizer-loop" and does most of the work:

#!/bin/sh

while true; do

powerstate=`cat /proc/acpi/ac_adapter/AC/state | awk '{print $2}'`

if [ $powerstate = "on-line" ]; then
nvidia-settings -q all > /dev/null
fi
sleep 25;
done

The second is named "powermizer-off" and starts up powermizer-loop when I log in, ensuring that only one copy runs at a time:

#!/bin/sh

killall powermizer-loop
~/powermizer-loop &

I put both of these scripts in my home directory and made them executable by doing:

chmod 755 powermizer-loop powermizer-off

Then to make powermizer-off run on login, I opened System --> Preferences --> Sessions, clicked on Add, and entered the command "/home/argilo/powermizer-off".

Of course, performance still suffers when running on battery, but hopefully NVidia will fix this problem in a future version of their driver.

One final bug is that EDID (Extended Display Identification Data) is misdetected, which causes problems with font sizes and greatly reduces the number of resolutions available in the NVidia X Server Settings application. (For example, I was unable to set my laptop's screen to 1024x768 for use with a projector during a presentation.) To correct this problem, I added the following lines to /etc/X11/xorg.conf in the "Screen" section:

Option "UseEdidDpi" "FALSE"
Option "DPI" "96 x 96"
Option "UseEdidFreqs" "FALSE"
Option "HorizSync" "40-70"

The first two lines fix the font size issue, and the last two lines fix the resolution problem. I'm not sure if the 40-70 values are actually correct, since I just took them from someone else's xorg.conf, but they seem to work.

NVidia seems to have corrected the EDID misdetection bug in the latest version of their driver, but it's not available in Hardy and I'm not aware of any easy way to install it.

== Suspend ==
Suspend is supposed to work out of the box if you're not using the Nvidia binary drivers. If you are using them, make sure the are updated as explained in the Display/Video section, and the following instructions will fix suspend to ram. Suspend to disk (hibernate) is not working at this time.

{{NOTE|These instructions worked on the T61p with type numbers 6460, 6457 (and perhaps 6465). It may also work with other type numbers.}}

To get suspend to ram working, you need to edit a configuration file, which apparently has some bad information in it.

{{cmduser |gksudo gedit /usr/share/hal/fdi/information/10freedesktop/20-video-quirk-pm-lenovo.fdi}}

Find the following section:
...

<match key="system.hardware.product" prefix_outof="6457;6460;6465">
<merge key="power_management.quirk.s3_bios" type="bool">true</merge>
<merge key="power_management.quirk.vbemode_restore" type="bool">true</merge>
</match>


<match key="system.hardware.product" prefix_outof="6459;7664;8918">
<merge key="power_management.quirk.none" type="bool">true</merge>
</match>


...

Remove the <code>6457;6460;</code> from the <code><match key="system.hardware.product" prefix_outof="6457;6460;6465"></code> line and add the following lines right before the <code></code> line:
<match key="system.hardware.product" prefix_outof="6457;6460">
<merge key="power_management.quirk.s3_bios" type="bool">false</merge>
<merge key="power_management.quirk.vbemode_restore" type="bool">true</merge>
</match>

Based on [https://bugs.launchpad.net/ubuntu/+source/hal-info/+bug/235284 Bug #235284 in hal-info (Ubuntu)]

On (at least) the 6457 model you'll need the latest binary Nvidia graphics drivers (173.14.09 at time of writing for Envy) to be able to resume from suspend. Additionally I have to switch to the X terminal manually by pressing alt+F7.
The sleep LED will blink for a while after resume, but will stop eventually and the wireless devices will be switched back on. You may experience some resetting of the display when that happens. Just move the cursor to regain your desktop. N.B. This does not seem to occur when waking after a long time of sleep.

== Bluetooth ==
If installed, bluetooth must be enabled with the command:

{{cmduser | echo enable | sudo tee /proc/acpi/ibm/bluetooth}}

Replace enable with disable to turn it off.

You can now connect devices by following the instructions at [https://help.ubuntu.com/community/BluetoothSetup Ubuntu Help Bluetooth Setup page]
{{NOTE|On (at least) the 6457 model the Bluetooth and Wireless LAN toggle button (Fn+F5) seems to work fine. Be aware of the additional hardware switch at the front of the machine. This needs to be in the green setting.}}

== Internal Microphone/Microphone Input Jack ==
The microphone is muted out of the box. In order to enable it, double click on the the speaker icon in the task bar or run {{cmduser | gnome-volume-control}}. Under File > Change Device, select "Capture: ALSA PCM on front:0 (AD198x Analog) via DMA (PulseAudio Mixer)" and set the master slider to about 75%. Make sure that the mute and recording buttons below the slider do not show red Xs.

Go back to the Change Device menu and select "HDA Intel (Alsa mixer)". Then go to the edit menu and select preferences. In the window that opens, make sure that the boxes for Capture, Capture1, and both instances of Input Source. The Volume Control panel should now have four tabs: Playback, Recording, Switches and Options. In the options tab, select Internal Mic for the internal microphone or Mic for the mic input jack for both Input sources. As far as i can tell, the second one down doesn't seem to actually do anything. Now in the recording tab you can mute Capture 1 and adjust the sensitivity of the mic with the Capture slider. You can use Sound Recorder in Applications > Sound & Video to test out your settings.

In the past, I have spent a fair amount of time messing with the PulseAudio settings on this install, so it would be great if someone with a relatively unaltered install could verify these instructions and post a confirmation. The main thing I did before was follow the PulseAudio howto here: [http://ubuntuforums.org/showthread.php?t=789578 HOWTO: PulseAudio Fixes & System-Wide Equalizer Support] [[User:Chazchaz101|Chazchaz101]] 11:05, 8 September 2008 (CEST)

=== What does not work? ===
*Screen brightness control

=== Screen brightness control ===
There is a known bug in Kubuntu/KDE 4.1 which causes acpi_fakekey information to be lost. This in turn breaks the /etc/acpi/video_brightnessdown.sh and video_brightnessup.sh scripts. See https://bugs.launchpad.net/ubuntu/+source/kdeutils-kde4/+bug/223643

Here's a workaround: change the above scripts as follows:
<pre>
root@t61p:/etc/acpi# cat video_brightnessdown.sh
#!/bin/bash
brightness=$(cat /sys/class/backlight/acpi_video1/actual_brightness)
new_brightness=$[brightness-1]
echo $new_brightness > /sys/class/backlight/acpi_video1/brightness

root@t61p:/etc/acpi# cat video_brightnessup.sh
#!/bin/bash
brightness=$(cat /sys/class/backlight/acpi_video1/actual_brightness)
new_brightness=$[brightness+1]
echo $new_brightness > /sys/class/backlight/acpi_video1/brightness

Install Ubuntu Gutsy Gibbon on a T61p

2008-03-15T19:52:15Z

Sgla1: /* Brightness */

== Installing Gutsy Gibbon (7.10) on a T61p ==

== Introduction ==

This document outlines configuring Ubuntu 7.10 (Gutsy Gibbon) on your Thinkpad T61p. Most items will work out of the box and a base install will provide you with an almost completely working system. Due to the modular nature of the T61 there are many different configuration, please read carefully and only make the changes specific to your system.

Feel free to update this Wiki with your information however please ask questions on the Talk page.

== Installation Notes ==

Note: On lenovo t61p thinkpad with nVidia Corporation Quadro FX 570M graphics card the installer fails to create a usable xorg.conf file and the system reboots into an unusable black screen as X refuses to start. This is caused by the installer selecting the nv driver, which does not support this card. Using the vesa driver will allow X to start.

<ol>
<li>Install Ubuntu onto the laptop. The Live CD will boot in safe graphics mode for most users (but not all). However, the splash screen does not work for 64-bit users and perhaps 32-bit users as well. Be patient the system will boot, even though the screen is black. It may be faster to do the initial install using the alternate CD (text mode install).</li>

<li>After it is installed, fix issue: "no x session on first reboot after install" (see steps below)</li>
</ol>

To fix this, you have to reboot into rescue mode and hand-edit xorg.conf to use vesa driver until the restricted nvidia driver is enabled.

Steps:
<ol>
<li>Choose Recovery Mode from the Grub boot menu.</li>
<li>Edit the xorg.conf file:
{{cmdroot|nano /etc/X11/xorg.conf}}</li>
<li>Scroll down until you see the section listed below and replace nv with vesa on the driver line:

<code>
Section "Device"
Identifier "nVidia Corporation G80 [Quadro FX 570M]"
Driver "nv"
BusID "PCI:1:0:0"
EndSection
</code></li>
<li>Hit {{key|Ctrl}}{{key|X}} to exit, {{key|Y}} then {{key|Enter}} to save.</li>
<li>Reboot: {{cmdroot|reboot}}</li>
</ol>

You should now get the GUI login, but all of the accelerated graphics eye candy will be disabled until you have updated the nvidia drivers as per the Display/Video Section.

If you have a Ubuntu 7.10 DVD, you could use the same to first launch a live CD version of Ubuntu. When the live CD boots up it asks for the installation of restricted nVidia drivers (internet connection required). Once the restricted drivers are installed. Use the "Install" option from the live CD session to start the installation of Ubuntu.

==Alternate Fix==
#Boot from Ubuntu 7.10 Desktop CD
#If during the black screen you suspect that the Ubuntu Live CD is not going to boot, or you don't wish to wait, restart the installation and explicitly choose to install in safe graphics mode.
#When the safe graphics installation halts while trying to initialize the X server, press CTRL-ALT-F1 to bring up the command line.
#At the prompt, start X in Vesa mode with the command 'startx'. Continue the Live CD install as usual, switching back to the GUI installation process with CTRL-ALT-Function key if there are interrupting messages from another X server startup process.
#When the system restarts, skip to the command line again and when X fails to start, type 'startx' again to go into vesa mode.
#Now install the restricted nvidia drivers to resolve the problem.

== Display/Video ==

The '''nv''' driver does not support the Nvidia 570M card at all. To enable accelerated 3D support click System->Administration->Restricted Drivers Manager. It will allow you to download and install an updated set of nvidia drivers. {{NOTE| If this is a fresh installation, you will get an error "can't get source for nvidia-glx-new", which means you need to update the package list: first, be sure that in System->Administration->Software Sources, the entry "Proprietary drivers for devices (restricted)" is checked. Then either click System->Administration->Update Manager->Check, or open a terminal and type "sudo apt-get update".}} On the next reboot you should get accelerated support and full graphics resolution (but still no splashscreen).{{NOTE| If the Restricted Drivers Manager fails to install the driver you can use the Envy tool from: http://albertomilone.com/nvidia_scripts1.html. This tool is unsupported and the only supported method of installing the Nvidia drivers is via Synaptic or the Restricted Drivers Manager}}
On the model with 1920x1200 video, the default fonts are very tiny. Change them with System->Preferences->Appearance->Fonts->Details.

== Brightness ==
source: [[ Installing Ubuntu 7.10 (Gutsy Gibbon) on a ThinkPad T61 ]]
====Nvidia Quadro N140 and 570M:====
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. In a few rare cases switching back to X (ctrl+alt+7) may freeze your computer with a black screen so save any open documents before switching out.

When using the '''vesa''' driver the brightness controls do work. So this problem seems to be related to the '''nvidia''' driver.

'''Update: Note that as of version 169.04 of the Nvidia driver brightness controls do work normally (with my 570M at least).''' (Gutsy Gibbon 7.10 comes with restricted Nvidia driver version 100.14). You can install the latest Nvidia binary drivers with "Envy" (see above)

== Audio ==
*Fix ALSA:
Gutsy uses ALSA v1.0.14 by default. Unfortunately, the audio card is not supported using that version. The solution is to upgrade to v1.0.15 or above. At the time of this writing, there are no packages for this version; however, new users should search Synaptic because that will make the process much easier: search for alsa-base and determine whether the available version is at least v1.0.15. If there are no packages available, the driver must be compiled from source. Follow this guide http://ubuntuforums.org/showthread.php?t=612605 to install the alsa v1.0.15.
After restarting, open a terminal and run alsamixer. Use the left/right arrow keys to select the channels; make sure that PCM and headphone are not muted (use m key). Muting/unmuting input channels can cause interference, so experiment to produce the best sound quality.
--[[User:Jbrown96|Jbrown96]] 22:57, 24 December 2007 (UTC)

I was unable to unmute sound using alsamixer or any other gui. Instead running this as root unmuted the channel and then everything worked fine. echo up > /proc/acpi/ibm/volume
--[[User:balsdorf|balsdorf]] 15:43, 30 January 2008

Everything except the mic works fine for me with ALSA 1.0.14. When I unmute the internal mic in alsamixer, it plays the mic sounds out the speakers.
--[[User:Chazchaz101|Chazchaz101]] 07:17, 28 December 2007 (UTC)

Same experience as Chazchaz101, but I could fix the microphone problem by adjusting the ALSA configuration as described in
source: [[Installing Ubuntu 7.10 (Gutsy_Gibbon) on a ThinkPad_T61#Microphone]].
--[[User:A-j|A-j]] 23:31, 28 January 2008 (UTC)

*fix sound buttons:
source: [[Installing Ubuntu 7.04 (Feisty Fawn) on a ThinkPad T61|Installing Ubuntu 7.04 (Feisty Fawn) on a ThinkPad T61]]

the volume control hotkeys are configured to control microphone volume out of the box.

fix: If you're using Gnome, from the System menu, click Preferences -> Sound, and in the Default Mixer Tracks field, choose PCM.

*fix volume control applet:

the volume control applet is configured to control microphone volume out of the box.

fix: If you're using Gnome, right-click the applet > preferences > Select the device and track to control

**do not change device (s/b HDA Intel)
**change track from Microphone to PCM

== Network/Internet ==

Some users report that IPv6 has large negative impact on internet connection speed (wired and wireless) on Ubuntu 7.10. If you are experiencing this, the following steps will allow you to disable IPv6 and restore your connection speed.
{{NOTE|There is a workaround to improve connectivity for Firefox. On the Firefox address bar type '''about:config''' and look for '''network.dns.disableIPv6''' and change its value to '''true'''[[Image:Ubuntu710_Firefox_Fix.png]].}}

Type the following in the terminal
{{cmduser|sudo gedit /etc/modprobe.d/aliases}}. The system may ask you to provide the Super User password. Once the file is opened, search for the following string, '''alias net-pf-10 ipv6'''.
Comment this line by prefixing a {{cmdresult|#}}. Now add a new line just below the commented line, '''alias net-pf-10 off'''.

[[Image:Update_to_Aliases.png]]

Now, save the file and restart Ubuntu.

== Suspend with Nvidia Binary Driver ==

*Fix suspend with Nvidia binary drivers:

Follow the directions on the Ubuntu wiki. [https://help.ubuntu.com/community/NvidiaLaptopBinaryDriverSuspend Nvidia Binary Driver Suspend]

==Bluetooth==
Bluetooth works out of the box. Pressing Fn-F5 once will enable bluetooth, disable wireless, pressing again, enable both and pressing one more time will disable bluetooth.

If you would like to set bluetooth state independently the script below determines the current bluetooth state and toggles the device on or off.

First create a new file named bluetooth-toggle:
{{cmdroot|sudo touch /usr/sbin/bluetooth-toggle}}

Now open a editor:
{{cmdroot|sudo gedit /usr/sbin/bluetooth-toggle}}

Paste the following script:

#!/bin/bash
cat /proc/acpi/ibm/bluetooth | awk '{ print $2 }' | while read line;
do
if [ $line == "enabled" ]; then
echo disable > /proc/acpi/ibm/bluetooth
else
echo enable > /proc/acpi/ibm/bluetooth
fi
break
done

Now set the execute permissions:
{{cmdroot|sudo chmod +x /usr/sbin/bluetooth-toggle}}

You can invoke the script out of the console by typing sudo bluetooth-toggle or create a menu icon by using the menu editor under preferences using gksudo bluetooth-toggle as command line.

source: [[Installing Ubuntu 7.10 (Gutsy Gibbon) on a ThinkPad T61]]

You can also create a launcher for this script that you can stick in the GNOME panel.

==Fingerprint Reader==

The [http://thinkfinger.sourceforge.net/ Thinkfinger] package allows you to swipe a finger in most places where you would have to type your password. At least for me, the most recent (0.3) version used here works with sudo, gksudo and on the login page but not with the the screen saver. Also, you are still required to type your user name on the login screen.

There appears to be a method to make the reader work for the screensaver, but I haven't tested it yet.

1) Add the launchpad repository to your sources:
{{cmduser| sudo gedit /etc/apt/sources.lst}}
note: if that file is not present or empty, try
{{cmduser| sudo gedit /etc/apt/sources.list}}
add the lines:
## LAUNCHPAD REPOSITORY
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

2) Install the following packages:

{{cmduser| sudo apt-get install thinkfinger-tools libpam-thinkfinger libthinkfinger0}}

3) Test the package installation and connection to the reader:

{{cmduser| sudo tf-tool --acquire && sudo tf-tool --verify}}

A completed test should look something like this:

frank@Laptop:~$ sudo tf-tool --acquire && sudo tf-tool --verify

ThinkFinger 0.3 (http://thinkfinger.sourceforge.net/)
Copyright (C) 2006, 2007 Timo Hoenig <thoenig@suse.de>

Initializing... done.
Please swipe your finger (successful swipes 3/3, failed swipes: 0)... done.
Storing data (/tmp/test.bir)... done.

ThinkFinger 0.3 (http://thinkfinger.sourceforge.net/)
Copyright (C) 2006, 2007 Timo Hoenig <thoenig@suse.de>

Initializing... done.
Please swipe your finger (successful swipes 1/1, failed swipes: 0)... done.
Result: Fingerprint does match.
frank@CLaptop:~$

4) Enable use of reader for authentication:

{{cmduser| sudo gedit /etc/pam.d/common-auth}}

add
auth sufficient pam_thinkfinger.so
before the pam_unix.so line and
try_first_pass
to the end of the pam_unix.so line.

5) Add User(s):
For each user:
{{cmduser| sudo tf-tool --add-user your_user_name}}

You can safely ignore the error:
Unable to set ACL of aquired file: /etc/pam_thinkfinger/charlie.bir: Operation not supported

6) Check uinput kernel module:

{{cmduser|lsmod | grep uinput}}
If the output starts with uinput, then you're done.
If you don't get any output, then it needs to be started and set to start on boot.

Start uinput:
{{cmduser|sudo modprobe uinput}}

Start on boot:
{{cmduser|sudo gedit /etc/modules}}
add the line:
uinput

At this point, you should be ready to swipe!

== Installing Gutsy Gibbon (7.10) on a T61p ==

=== Introduction ===

This document outlines configuring Ubuntu 7.10 (Gutsy Gibbon) on your Thinkpad T61p. Most items will work out of the box and a base install will provide you with an almost completely working system. Due to the modular nature of the T61 there are many different configuration, please read carefully and only make the changes specific to your system.

Feel free to update this Wiki with your information however please ask questions on the Talk page.

=== Installation Notes ===

*Booting with the live CD not tested; there are no problems with graphics during install with the 'alternate' cd

*fix no x session on first reboot after install

On lenovo t61p thinkpad with nVidia Corporation Quadro FX 570M graphics card the installer fails to create a usable xorg.conf file and the system reboots into an unusable black screen as x refuses to start. The installer selects the nv driver, which does not support this card.

fix: reboot into rescue mode and hand-edit xorg.conf to use vesa driver until the restricted nvidia driver is enabled.

== Display/Video ==

The '''nv''' driver does not support the Nvidia 570M card at all. To enable accelerated 3D support click System->Administration->Restricted Drivers Manager {{NOTE| If the Restricted Drivers Manager fails to install the driver you can use the Envy tool from: http://albertomilone.com/nvidia_scripts1.html. This tool is unsupported and the only supported method of installing the Nvidia drivers is via Synaptics and the Restricted Drivers Manager}}

=== Brightness ===
source: [[ Installing Ubuntu 7.10 (Gutsy Gibbon) on a ThinkPad T61 ]]
====Nvidia Quadro N140 and 570M:====
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. In a few rare cases switching back to X (ctrl+alt+7) may freeze your computer with a black screen so save any open documents before switching out.

When using the '''vesa''' driver the brightness controls do work. So this problem seems to be related to the '''nvidia''' driver.

== Audio ==
*fix sound buttons:
source: [[Installing Ubuntu 7.04 (Feisty Fawn) on a ThinkPad T61|Installing Ubuntu 7.04 (Feisty Fawn) on a ThinkPad T61]]

the volume control hotkeys are configured to control microphone volume out of the box.

fix: If you're using Gnome, from the System menu, click Preferences -> Sound, and in the Default Mixer Tracks field, choose PCM.

*fix volume control applet:

the volume control applet is configured to control microphone volume out of the box.

fix: If you're using Gnome, right-click the applet > preferences > Select the device and track to control

**do not change device (s/b HDA Intel)

Sgla1:

==Introduction==

This document outlines configuring Ubuntu 7.10 (Gutsy Gibbon) on your Thinkpad T61. Most items will work out of the box and a base install should provide you with a completely working system. Due to the modular nature of the T61 there are many different configuration, please read carefully and only make the changes specific to your system.

Feel free to update this Wiki with your information however please ask questions on the Talk page.

==Installation Notes ==

*If booting with the live CD gives you a blank screen you should select the "Safe Graphics" menu choice.

== Display/Video ==

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

Due to [https://bugs.launchpad.net/xorg-server/+bug/111257 | bug 111257], compiz is disabled on the Intel i965 based video cards. To fix it, download this file[http://www.fileden.com/files/2007/9/28/1467484/compizubuntuintel.zip], unzip it, and follow the instructions in "description and README."

''Note: If you enable Compiz on an Intel card there will be issues with viewing media files, please see the bug report above for details''

'''Nvidia''' 2D video works out of the box, to enable accelerated 3D support click System->Administration->Restricted Drivers Manager {{NOTE| If the Restricted Drivers Manager fails to install the driver you can use the Envy tool from: http://albertomilone.com/nvidia_scripts1.html. This tool is unsupported and the only supported method of installing the Nvidia drivers is via Synaptics and the Restricted Drivers Manager}}

===Multiple Monitors===

If you previously used Xinerama this is no longer a supported option, you should use one of the tools described below to configure dual displays.

'''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. Note:
Twinview works but a movie will span both the laptop screen and second monitor or projector.

'''Intel X3100:'''

Plugging in an external monitor works, but is a clone of the built-in LCD by default. Using the Screens and Graphics tool located under Administration you can setup the second monitor as an extension of the existing screen or a clone for presentations.

'''Setting up dual monitors via the command line'''

If you like doing it via the command line and are using the Intel drivers or the open-source "nv" driver you can use this example (''Note all this should be possible using the Screens and Graphics tool so only make this change if you prefer the command line method''):

This 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:

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), some users consider the default fonts too be too large ([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 should work out of the box on a fresh install.

====Nvidia Quadro N140 and 570M:====
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. In a few rare cases switching back to X (ctrl+alt+7) may freeze your computer with a black screen so save any open documents before switching out.

== Audio ==

=== Inextricably Linked to the Modem ===
Make sure that you have the modem enabled in the BIOS. If it is disabled, you may discover (with much consternation) that your audio is also disabled. In this situation, your drivers may still load, but you will get an error message whenever you try to play audio.

After trying all of the ALSA related fixes for this machine, with no love, I remembered what a colleague had said about his T60, and tried this on a hunch. Blammo, it worked!

===Enabling Audio 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.

The mute button on the laptop does not work.

===Microphone===

There have been reports that the microphone may not work, please add your input to the talk page [http://www.thinkwiki.org/wiki/Talk:Installing_Ubuntu_7.10_%28Gutsy_Gibbon%29_on_a_ThinkPad_T61#Microphone] and update this section when a consensus on the problem and solution has been reached.

===Sound Cracking===

There have been intermittent reports of users experiencing cracking when listening to audio. Here are a few possible solutions:

* Try to switch to the OSS driver in system => preference => sound => devices => Music and movies, select OSS - Open sound system (instead of ALSA)

* If this issue is only occurring for Rhythmbox go to Edit > Preferences > Playback > and Check "Use Crossfading Backend". Restart Rhythmbox and you should have better audio quality.

* Check that the microphone is muted and modify your mixer settings by moving items like PCM down halfway and see if the cracking goes away.

===Hissing===
Some users experience hissing during playback, and even when idle. To solve this mute the microphone when it is not in use:

# Run "alsamixer".
# Arrow over to "Mic", and hit "M" to mute.
# Arrow over to the first "Docking", and hit "M" to mute.
# Arrow to the first "Internal", and hit "M" to mute.

Now, make sure that "Headphone" and/or "Speaker" are _not_ muted, and that "PCM" is at a reasonable level (say ~70) so you don't make your ears bleed, and try playing something back. ''(<Esc> will exit alsamixer)''

== Modem ==

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

==Bluetooth==
Bluetooth works out of the box. Pressing Fn-F5 once will enable bluetooth, disable wireless, pressing again, enable both and pressing one more time will disable bluetooth.

If you would like to set bluetooth state independently the script below determines the current bluetooth state and toggles the device on or off.

First create a new file named bluetooth-toggle:
{{cmdroot|sudo touch /usr/sbin/bluetooth-toggle}}

Now open a editor:
{{cmdroot|sudo gedit /usr/sbin/bluetooth-toggle}}

Paste the following script:

cat /proc/acpi/ibm/bluetooth | awk '{ print $2 }' | while read line;
do
if [ $line == "enabled" ]; then
echo disable > /proc/acpi/ibm/bluetooth
else
echo enable > /proc/acpi/ibm/bluetooth
fi
break
done

Now set the execute permissions:
{{cmdroot|sudo chmod +x /usr/sbin/bluetooth-toggle}}

You can invoke the script out of the console by typing sudo bluetooth-toggle or create a menu icon by using the menu editor under preferences using gksudo bluetooth-toggle as command line.

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

Prebuilt packages are available from jldugger using Launchpad's PPA:

Add the thinkfinger package repository by creating {{path|/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 the package database and install packages:

{{cmduser|sudo apt-get update}}
{{cmduser|sudo apt-get install libpam-thinkfinger libthinkfinger-dev libthinkfinger-doc libthinkfinger0 thinkfinger-tools}}

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

auth sufficient pam_thinkfinger.so
auth required pam_unix.so try_first_pass

Edit {{path|/etc/modules}} and add the following line:

uinput

Load the module manually for this session:

{{cmduser| sudo modprobe uinput}}

Summary:
* 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.

== 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.
Note that /etc/X11/xorg.conf will be changed and the edge scrolling will be disabled after running nvidia-xconfig , copy the trackpad section from the backup of xorg.conf

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 for intel graphics cards===

This fix is for Intel Graphics Cards only.

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.

=== How to Suspend with nVidia 140m/570m ===

The suspend to RAM will work with the nVidia card and the proprietary drivers, but it requires some file editing. It did not work for me out of the box. Using the package manager, download and install the latest nVidia drivers (100.14.19+2.6.2.4-12.4 at time of writing). I also had to use the 2.6.22-12-generic kernel image (the 2.6.22-13 image did not work with this driver --- I'm assuming it has to match wit the nVidia version, but I am not an expert).

Once you have it installed and working, you have to make a change to {{path|/etc/default/acpi-support}}. Open the file in your favorite editor and change the following lines:

$ sudo nano /etc/default/acpi-support

{{path|/etc/default/acpi-support}}
# Should we save and restore state using the VESA BIOS Extensions?
SAVE_VBE_STATE=false
...
# Should we attempt to warm-boot the video hardware on resume?
POST_VIDEO=false
...
# Set the following to "platform" if you want to use ACPI to shut down
# your machine on hibernation
HIBERNATE_MODE=platform

This allowed me to suspend and resume, but after two suspends the wireless wouldn't work anymore. Theoretically, ACPI unloads the network drivers before suspending, but it doesn't seem to work correctly so I added these to the blacklist modules manually (in the same file as above:

{{path|/etc/default/acpi-support}}
# Add modules to this list to have them removed before suspend and reloaded
# on resume. An example would be MODULES="em8300 yenta_socket"
#
# Note that network cards and USB controllers will automatically be unloaded
# unless they're listed in MODULES_WHITELIST
MODULES="iwl4965 iwlwifi_mac80211 cfg80211"

Your wifi modules may be different. (I have the intel AGN wireless card -- I don't know if these modules are different for other cards.)

This allows me to suspend to ram; I haven't had any problems with it so far. I haven't gotten hibernate (suspend to disk) working, so there may be additional things you need to do for that. (I think part of my problem is that I don't have enough swap, but I don't care enough to actually fix it.)

/*The fix does not work for me. I have a T61 7664-17U(NVS 140m, 4965agn). The computers suspend, but when it wakes up it hangs up and I have to pull out the battery to restart it.*/

General hint: Do not install the package "hibernate" or "uswsusp" or the gnome-power-manager will fail to suspend/hibernate your computer. If you have installed the package don't forget to purge the configuration. (sudo apt-get remove hibernate --purge, uswsusp resp.)

== 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 cards both tested.

'''Bluetooth:''' Tested with both a bluetooth headset and an HTC 8525

'''Network Card''' Intel 10/100/1000 tested

'''Firewire''' Tested with hard drive

'''Wireless switch'''

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

'''Webcam'''

'''Headphones''' You may need to enable Headphone out: Right-click on the volume control and select open volume control. Click the switches tab and then check the headphones box.

'''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 >>does not work on all machines<<
* 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 ===
* details?

=== Interrupt problem ===
* https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/126369
* USB ports can end up temporarily disabled
* Wifi can break
* integrated cardreader can be disabled
* bluetooth can be disabled
* Setting IRQ's to "Auto" from factory default of "11" in the BIOS seems to help some people.

=== Volume keys ===
* Control mic instead of speakers by default
* https://bugs.launchpad.net/ubuntu/+bug/136287

=== Wireless activity LED ===
doesn't seem to flicker properly. (?)

== 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.

Installing Ubuntu 7.10 (Gutsy Gibbon) on a ThinkPad T61

2007-10-21T18:32:51Z

Sgla1: /* Installation Notes */

==Introduction==

This document outlines configuring Ubuntu 7.10 (Gutsy Gibbon) on your Thinkpad T61. Most items will work out of the box and a base install should provide you with a completely working system. Due to the modular nature of the T61 there are many different configuration, please read carefully and only make the changes specific to your system.

Feel free to update this Wiki with your information however please ask questions on the Talk page.

==Installation Notes ==

*If booting with the live CD gives you a blank screen you should select the "Safe Graphics" menu choice.

*fix no x session on first reboot after install
On lenovo t61p thinkpad with nVidia Corporation Quadro FX 570M graphics card the installer fails to create a usable xorg.conf file and the system reboots into an unusable black screen as x refuses to start. The installer selects the nv driver, which does not support this card.

fix: reboot into rescue mode and hand-edit xorg.conf to use vesa driver until the restricted nvidia driver is enabled.

== Display/Video ==

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

Due to [https://bugs.launchpad.net/xorg-server/+bug/111257 | bug 111257], compiz is disabled on the Intel i965 based video cards. To fix it, download this file[http://www.fileden.com/files/2007/9/28/1467484/compizubuntuintel.zip], unzip it, and follow the instructions in "description and README."

''Note: If you enable Compiz on an Intel card there will be issues with viewing media files, please see the bug report above for details''

'''Nvidia''' 2D video works out of the box, to enable accelerated 3D support click System->Administration->Restricted Drivers Manager {{NOTE| If the Restricted Drivers Manager fails to install the driver you can use the Envy tool from: http://albertomilone.com/nvidia_scripts1.html. This tool is unsupported and the only supported method of installing the Nvidia drivers is via Synaptics and the Restricted Drivers Manager}}

===Multiple Monitors===

If you previously used Xinerama this is no longer a supported option, you should use one of the tools described below to configure dual displays.

'''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. Note:
Twinview works but a movie will span both the laptop screen and second monitor or projector.

'''Intel X3100:'''

Plugging in an external monitor works, but is a clone of the built-in LCD by default. Using the Screens and Graphics tool located under Administration you can setup the second monitor as an extension of the existing screen or a clone for presentations.

'''Setting up dual monitors via the command line'''

If you like doing it via the command line and are using the Intel drivers or the open-source "nv" driver you can use this example (''Note all this should be possible using the Screens and Graphics tool so only make this change if you prefer the command line method''):

This 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:

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), some users consider the default fonts too be too large ([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 should work out of the box on a fresh install.

====Nvidia Quadro N140 and 570M:====
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. In a few rare cases switching back to X (ctrl+alt+7) may freeze your computer with a black screen so save any open documents before switching out.

== Audio ==

=== Inextricably Linked to the Modem ===
Make sure that you have the modem enabled in the BIOS. If it is disabled, you may discover (with much consternation) that your audio is also disabled. In this situation, your drivers may still load, but you will get an error message whenever you try to play audio.

After trying all of the ALSA related fixes for this machine, with no love, I remembered what a colleague had said about his T60, and tried this on a hunch. Blammo, it worked!

===Enabling Audio 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.

The mute button on the laptop does not work.

===Microphone===

There have been reports that the microphone may not work, please add your input to the talk page [http://www.thinkwiki.org/wiki/Talk:Installing_Ubuntu_7.10_%28Gutsy_Gibbon%29_on_a_ThinkPad_T61#Microphone] and update this section when a consensus on the problem and solution has been reached.

===Sound Cracking===

There have been intermittent reports of users experiencing cracking when listening to audio. Here are a few possible solutions:

* Try to switch to the OSS driver in system => preference => sound => devices => Music and movies, select OSS - Open sound system (instead of ALSA)

* If this issue is only occurring for Rhythmbox go to Edit > Preferences > Playback > and Check "Use Crossfading Backend". Restart Rhythmbox and you should have better audio quality.

* Check that the microphone is muted and modify your mixer settings by moving items like PCM down halfway and see if the cracking goes away.

===Hissing===
Some users experience hissing during playback, and even when idle. To solve this mute the microphone when it is not in use:

# Run "alsamixer".
# Arrow over to "Mic", and hit "M" to mute.
# Arrow over to the first "Docking", and hit "M" to mute.
# Arrow to the first "Internal", and hit "M" to mute.

Now, make sure that "Headphone" and/or "Speaker" are _not_ muted, and that "PCM" is at a reasonable level (say ~70) so you don't make your ears bleed, and try playing something back. ''(<Esc> will exit alsamixer)''

== Modem ==

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

==Bluetooth==
Bluetooth works out of the box. Pressing Fn-F5 once will enable bluetooth, disable wireless, pressing again, enable both and pressing one more time will disable bluetooth.

If you would like to set bluetooth state independently the script below determines the current bluetooth state and toggles the device on or off.

First create a new file named bluetooth-toggle:
{{cmdroot|sudo touch /usr/sbin/bluetooth-toggle}}

Now open a editor:
{{cmdroot|sudo gedit /usr/sbin/bluetooth-toggle}}

Paste the following script:

cat /proc/acpi/ibm/bluetooth | awk '{ print $2 }' | while read line;
do
if [ $line == "enabled" ]; then
echo disable > /proc/acpi/ibm/bluetooth
else
echo enable > /proc/acpi/ibm/bluetooth
fi
break
done

Now set the execute permissions:
{{cmdroot|sudo chmod +x /usr/sbin/bluetooth-toggle}}

You can invoke the script out of the console by typing sudo bluetooth-toggle or create a menu icon by using the menu editor under preferences using gksudo bluetooth-toggle as command line.

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

Prebuilt packages are available from jldugger using Launchpad's PPA:

Add the thinkfinger package repository by creating {{path|/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 the package database and install packages:

{{cmduser|sudo apt-get update}}
{{cmduser|sudo apt-get install libpam-thinkfinger libthinkfinger-dev libthinkfinger-doc libthinkfinger0 thinkfinger-tools}}

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

auth sufficient pam_thinkfinger.so
auth required pam_unix.so try_first_pass

Edit {{path|/etc/modules}} and add the following line:

uinput

Load the module manually for this session:

{{cmduser| sudo modprobe uinput}}

Summary:
* 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.

== 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.
Note that /etc/X11/xorg.conf will be changed and the edge scrolling will be disabled after running nvidia-xconfig , copy the trackpad section from the backup of xorg.conf

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 for intel graphics cards===

This fix is for Intel Graphics Cards only.

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.

=== How to Suspend with nVidia 140m/570m ===

The suspend to RAM will work with the nVidia card and the proprietary drivers, but it requires some file editing. It did not work for me out of the box. Using the package manager, download and install the latest nVidia drivers (100.14.19+2.6.2.4-12.4 at time of writing). I also had to use the 2.6.22-12-generic kernel image (the 2.6.22-13 image did not work with this driver --- I'm assuming it has to match wit the nVidia version, but I am not an expert).

Once you have it installed and working, you have to make a change to {{path|/etc/default/acpi-support}}. Open the file in your favorite editor and change the following lines:

$ sudo nano /etc/default/acpi-support

{{path|/etc/default/acpi-support}}
# Should we save and restore state using the VESA BIOS Extensions?
SAVE_VBE_STATE=false
...
# Should we attempt to warm-boot the video hardware on resume?
POST_VIDEO=false
...
# Set the following to "platform" if you want to use ACPI to shut down
# your machine on hibernation
HIBERNATE_MODE=platform

This allowed me to suspend and resume, but after two suspends the wireless wouldn't work anymore. Theoretically, ACPI unloads the network drivers before suspending, but it doesn't seem to work correctly so I added these to the blacklist modules manually (in the same file as above:

{{path|/etc/default/acpi-support}}
# Add modules to this list to have them removed before suspend and reloaded
# on resume. An example would be MODULES="em8300 yenta_socket"
#
# Note that network cards and USB controllers will automatically be unloaded
# unless they're listed in MODULES_WHITELIST
MODULES="iwl4965 iwlwifi_mac80211 cfg80211"

Your wifi modules may be different. (I have the intel AGN wireless card -- I don't know if these modules are different for other cards.)

This allows me to suspend to ram; I haven't had any problems with it so far. I haven't gotten hibernate (suspend to disk) working, so there may be additional things you need to do for that. (I think part of my problem is that I don't have enough swap, but I don't care enough to actually fix it.)

/*The fix does not work for me. I have a T61 7664-17U(NVS 140m, 4965agn). The computers suspend, but when it wakes up it hangs up and I have to pull out the battery to restart it.*/

General hint: Do not install the package "hibernate" or "uswsusp" or the gnome-power-manager will fail to suspend/hibernate your computer. If you have installed the package don't forget to purge the configuration. (sudo apt-get remove hibernate --purge, uswsusp resp.)

== 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 cards both tested.

'''Bluetooth:''' Tested with both a bluetooth headset and an HTC 8525

'''Network Card''' Intel 10/100/1000 tested

'''Firewire''' Tested with hard drive

'''Wireless switch'''

'''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 ===
* details?

=== Interrupt problem ===
* https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/126369
* USB ports can end up temporarily disabled
* Wifi can break
* integrated cardreader can be disabled
* bluetooth can be disabled
* Setting IRQ's to "Auto" from factory default of "11" in the BIOS seems to help some people.

=== Volume keys ===
* Control mic instead of speakers by default
* https://bugs.launchpad.net/ubuntu/+bug/136287

=== Wireless activity LED ===
doesn't seem to flicker properly. (?)

== 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.

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):
