''This part is taken from [[Install Ubuntu Hardy Heron on a T61p | Hardy installation instructions]].''

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. You will have a choice between the 173 and 177 version of the driver. I would strongly recommend the latter one, because it will provide Suspend to disk functionality in favour of the 173 version.

This should also install the "NVidia X Server Settings" program in System --> Administration.

At the time of writing I am not able to restart X or log out from my GNOME session. X will fail to start and will eventually fall back to failsafe config (VESA drivers). This happens on my Quadro FX 570M and I'm not sure it is an issue of the new NVidia driver or the new X.org version in Intrepid.

{{NOTE|You should even install the binary NVidia driver if you won't use 3D acceleration because the open source nv driver will drain your battery much faster, because it doesn't support PowerMizer at all. This will keep the GPU in full speed all the time and will consume around 12 Watts more because of that (for the Quadro FX 570M), according to Powertop. That is 50% of the total usage!}}

=Optional=
==Fix for choppy Compiz animations==

The NVidia driver does not report the correct refresh rate of the display to Compiz, resulting in choppy animations and effects. 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. This will improve the smoothness of the window animations significantly if you're sensitive to the choppy animations.

Compiz animations can also be 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. It seems that the interval of the PowerMizer is way too long and is not speeding up when using in bursts. Fortunately, the situation seems to have improved in version 177 of the NVidia driver. To workaround 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 a+x powermizer-loop powermizer-off

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

==== EDID misdetection ====

EDID (Extended Display Identification Data) might be misdetected for your display, which 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.) If you encounter this problem, add the following lines to /etc/X11/xorg.conf in the "Screen" section:

Option "UseEdidFreqs" "FALSE"
Option "HorizSync" "40-70"

The 40-70 values are just an example. They seem to work well with my 1680x1050 display. You should put the values of your display there.

=Problems=
== Not able to restart X ==
This is quite an issue when you want to switch user or log out. The Xorg.0.log file doesn't give any errors or hints. Surprisingly both Suspend to RAM and Suspend to Disk are not failing.

It is a known issue in the 177 version of the binary NVidia driver which has not yet been addressed by NVidia. See Launchpad bug [http://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-177/+bug/258357 258357]. Workaround is to use the older 173 version (without Suspend to Disk functionality and with slower resume from Suspend to RAM).

== Wireless not working after resume (Atheros) ==
After resuming from suspend, I am unable to reconnect to my wireless network. Network Manager asks me for my password over and over again but never succeeds in connecting. I'm using the Thinkpad (Atheros) A/B/G wireless card.

To fix this problem, I followed the instructions listed at https://bugs.launchpad.net/ubuntu/+source/linux-restricted-modules/+bug/275692. Specifically, I created a file called /etc/pm/config.d/01-modules and put the following line in it:

SUSPEND_MODULES="ath_pci"

== Radio Killswitch ==
When killing Wireless LAN with the killswitch at the front, you won't be able to get WLAN back up after switching back. See Launchpad bugs [http://bugs.launchpad.net/ubuntu/+source/hal/+bug/289286 289286] and [http://bugs.launchpad.net/ubuntu/+source/linux-ubuntu-modules-2.6.24/+bug/193970 193970] and the [https://wiki.ubuntu.com/IntrepidReleaseNotes#Cannot%20reactivate%20Intel%203945/4965%20wireless%20if%20booting%20with%20killswitch%20enabled Release Notes] on the Ubuntu Wiki.

This will be solved in intrepid-updates eventually.

= Information, not Ubuntu issues =
== Brightness control on battery power ==
By default, when unplugging the AC power while the system is running, the brightness of the display goes down even when you have set not to in the Power Management settings and you are not able to reach a brightness level as high as possible when connected to AC power. This is not a software setting or GNOME bug, but a BIOS setting. In the BIOS you can find a brightness setting in the Power section. Set it to high for normal, expected behavior. You can let the GNOME Power Manager still lower the brightness, but you will be able to increase it when needed.

= Compared to Hardy =
Why upgrade your T61p to Intrepid or why not? (Specific for T61p)
== Improvements ==
*Ricoh SD card reader now reads read-only SD card. (Tested with Adata 150X 2GB SD card)
*Newer Wireless LAN drivers. For Intel cards this results in working LED, more sensitive reception, increased stability of connections and some 802.1x bugfixes.
*Out-of-the-box Suspend to RAM functionality (also faster resume).
*Working but slow Suspend to Disk functionality.
== Bugs and Regressions ==
*Hard radio killswitch (at the front) cannot bring WLAN back up after killing it.
*Atheros WLAN not working after resume from Suspend to RAM (but a workaround is available; [[#Wireless_not_working_after_resume_.28Atheros.29|see above]]).

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. You will have a choice between the 173 and 177 version of the driver. I would strongly recommend the latter one, because it will provide Suspend to disk functionality in favour of the 173 version.

This should also install the "NVidia X Server Settings" program in System --> Administration.

At the time of writing I am not able to restart X or log out from my GNOME session. X will fail to start and will eventually fall back to failsafe config (VESA drivers). This happens on my Quadro FX 570M and I'm not sure it is an issue of the new NVidia driver or the new X.org version in Intrepid.

{{NOTE|You should even install the binary NVidia driver if you won't use 3D acceleration because the open source nv driver will drain your battery much faster, because it doesn't support PowerMizer at all. This will keep the GPU in full speed all the time and will consume around 12 Watts more because of that (for the Quadro FX 570M), according to Powertop. That is 50% of the total usage!}}

==Fix for choppy Compiz animations==

The NVidia driver does not report the correct refresh rate of the display to Compiz, resulting in choppy animations and effects. 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. This will improve the smoothness of the window animations significantly if you're sensitive to the choppy animations.

Compiz animations can also be 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. It seems that the interval of the PowerMizer is way too long and is not speeding up when using in bursts. Fortunately, the situation seems to have improved in version 177 of the NVidia driver. To workaround 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 a+x powermizer-loop powermizer-off

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

==== EDID misdetection ====

EDID (Extended Display Identification Data) might be misdetected for your display, which 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.) If you encounter this problem, add the following lines to /etc/X11/xorg.conf in the "Screen" section:

Option "UseEdidFreqs" "FALSE"
Option "HorizSync" "40-70"

The 40-70 values are just an example. They seem to work well with my 1680x1050 display. You should put the values of your display there.

=Problems=
== Not able to restart X ==
This is quite an issue when you want to switch user or log out. The Xorg.0.log file doesn't give any errors or hints. Surprisingly both Suspend to RAM and Suspend to Disk are not failing.

It is a known issue in the 177 version of the binary NVidia driver which has not yet been addressed by NVidia. See Launchpad bug [http://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-177/+bug/258357 258357]. Workaround is to use the older 173 version (without Suspend to Disk functionality and with slower resume from Suspend to RAM).

== Wireless not working after resume (Atheros) ==
After resuming from suspend, I am unable to reconnect to my wireless network. Network Manager asks me for my password over and over again but never succeeds in connecting. I'm using the Thinkpad (Atheros) A/B/G wireless card.

To fix this problem, I followed the instructions listed at https://bugs.launchpad.net/ubuntu/+source/linux-restricted-modules/+bug/275692. Specifically, I created a file called /etc/pm/config.d/01-modules and put the following line in it:

SUSPEND_MODULES="ath_pci" and now resuming works.

== Radio Killswitch ==
When killing Wireless LAN with the killswitch at the front, you won't be able to get WLAN back up after switching back. See Launchpad bugs [http://bugs.launchpad.net/ubuntu/+source/hal/+bug/289286 289286] and [http://bugs.launchpad.net/ubuntu/+source/linux-ubuntu-modules-2.6.24/+bug/193970 193970] and the [https://wiki.ubuntu.com/IntrepidReleaseNotes#Cannot%20reactivate%20Intel%203945/4965%20wireless%20if%20booting%20with%20killswitch%20enabled Release Notes] on the Ubuntu Wiki.

This will be solved in intrepid-updates eventually.

= Information, not Ubuntu issues =
== Brightness control on battery power ==
By default, when unplugging the AC power while the system is running, the brightness of the display goes down even when you have set not to in the Power Management settings and you are not able to reach a brightness level as high as possible when connected to AC power. This is not a software setting or GNOME bug, but a BIOS setting. In the BIOS you can find a brightness setting in the Power section. Set it to high for normal, expected behavior. You can let the GNOME Power Manager still lower the brightness, but you will be able to increase it when needed.

= Compared to Hardy =
Why upgrade your T61p to Intrepid or why not? (Specific for T61p)
== Improvements ==
*Ricoh SD card reader now reads read-only SD card. (Tested with Adata 150X 2GB SD card)
*Newer Wireless LAN drivers. For Intel cards this results in working LED, more sensitive reception, increased stability of connections and some 802.1x bugfixes.
*Out-of-the-box Suspend to RAM functionality (also faster resume).
*Working but slow Suspend to Disk functionality.
== Bugs and Regressions ==
*Hard radio killswitch (at the front) cannot bring WLAN back up after killing it.
*Atheros WLAN not working after resume from Suspend to RAM.

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. You will have a choice between the 173 and 177 version of the driver. I would strongly recommend the latter one, because it will provide Suspend to disk functionality in favour of the 173 version.

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. You will have a choiche between the 173 and 177 version of the driver. I would strongly recommend the latter one, because it will provide Suspend to disk functionality in favour of the 173 version.

This should also install the "NVidia X Server Settings" program in System --> Administration.

At the time of writing I am not able to restart X or log out from my GNOME session. X will fail to start and will eventually fall back to failsafe config (VESA drivers). This happens on my Quadro FX 570M and I'm not sure it is an issue of the new NVidia driver or the new X.org version in Intrepid.

{{NOTE|You should even install the binary NVidia driver if you won't use 3D acceleration because the open source nv driver will drain your battery much faster, because it doesn't support PowerMizer at all. This will keep the GPU in full speed all the time and will consume around 12 Watts more because of that (for the Quadro FX 570M), according to Powertop. That is 50% of the total usage!}}

=Optional=
==Fix for choppy Compiz animations==

The NVidia driver does not report the correct refresh rate of the display to Compiz, resulting in choppy animations and effects. 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. This will improve the smoothness of the window animations significantly if you're sensitive to the choppy animations.

Compiz animations can also be 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. It seems that the interval of the PowerMizer is way too long and is not speeding up when using in bursts. Fortunately, the situation seems to have improved in version 177 of the NVidia driver. To workaround 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 a+x powermizer-loop powermizer-off

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

{{NOTE|As far as I can see, the EDID misdetection bug is fixed in the 177 version of the NVidia binary driver.}}

By default, when unplugging the AC power while the system is running, the brightness of the display goes down even when you have set not to in the Power Management settings and you are not able to reach a brightness level as high as possible when connected to AC power. This is not a software setting or GNOME bug, but a BIOS setting. In the BIOS you can find a brightness setting in the Power section. Set it to high for normal, expected behavior. You can let the GNOME Power Manager still lower the brightness, but you will be able to increase it when needed.

Installing Ubuntu 8.04 (Hardy Heron) on a ThinkPad T61p

2008-07-07T03:18:23Z

Argilo: /* What works out of the box */

==What works out of the box==
*Video driver
*Wireless (Intel 3945ABG or 4965AGN)
**Only tested G mode
*Video (VESA)
**Hardware Drivers panel offers to install NVidia proprietary drivers on first boot
*Touchpoint and trackpad
*Volume control buttons
*Screen brightness control

== Display / Video ==

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, 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.

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.

Installing Ubuntu 8.04 (Hardy Heron) on a ThinkPad T61p

2008-07-07T03:17:53Z

Argilo: /* What works out of the box */ Small updates

==What works out of the box==
*Video driver
*Wireless (Intel 3945ABG or 4965AGN)
**Only tested G mode
*Video (VESA)
**Hardware Drivers panel offers to install nvidia proprietary drivers on first boot
*Touchpoint and trackpad
*Volume control buttons
*Screen brightness control

== Display / Video ==

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, 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.

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".

== Display / Video ==

To enable 3D acceleration, the proprietary NVidia driver must be installed. To do this, I installed EnvyNG (envyng-gtk in Synaptic), then ran it (System Tools --> EnvyNG) and asked it to install the NVidia driver.

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. This bug is documented in Launchpad [https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/160264] and a partial workaround is available [https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/160264/comments/69]. The workaround may eventually become a part of Hardy.

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.

Finally, 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.

To enable 3D acceleration, the proprietary NVidia driver must be installed. To do this, I installed EnvyNG (envyng-gtk in Synaptic), then ran it (System Tools --> EnvyNG) and asked it to install the NVidia driver.

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. This bug is documented in Launchpad [https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/160264] and a partial workaround is available [https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/160264/comments/69]. The workaround may eventually become a part of Hardy.

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.
