== Rolling back ==

If the driver does not work for you, or is not better, you should rollback to
the original Ubuntu one. Remove the two lines from `/etc/apt/sources.list`
again, and install the original one again:

{{{
 $ sudo apt-get install xserver-xorg-video-intel
}}}

If X.org does not start at all, you should change to a text terminal by
pressing Ctrl+Alt+F2, logging in, and use "sudo nano" to edit
`/etc/apt/sources.list`. After installing `xserver-xorg-video-intel`, restart
the computer with "sudo reboot".

The problem

As Described in X/Troubleshooting/IntelPerformance, some laptops with intel graphics hardware experience a serious performance degration after upgrading from intrepid to jaunty. The reasons for that are already explained on that page. This page explains how to revert the driver to the version in intrepid.

Installing the package

Add the following lines to your /etc/apt/sources.list: 

 deb http://ppa.launchpad.net/siretart/ppa/ubuntu jaunty main
 deb-src http://ppa.launchpad.net/siretart/ppa/ubuntu jaunty main

See https://help.launchpad.net/Packaging/PPA#Adding%20a%20PPA%20to%20your%20Ubuntu%20repositories for additional information how to add GPG keys to your system.

Install the driver: 

 $ sudo apt-get update
 $ sudo apt-get install xserver-xorg-video-intel-2.4

Now you should be set. Restart X and see if the graphics performance from intrepid is restored.

Do I need to change my xorg.conf file? ==> May not work. Situation not improved without xorg.conf change??

Rolling back

If the driver does not work for you, or is not better, you should rollback to the original Ubuntu one. Remove the two lines from /etc/apt/sources.list again, and install the original one again: 

 $ sudo apt-get install xserver-xorg-video-intel

If X.org does not start at all, you should change to a text terminal by pressing Ctrl+Alt+F2, logging in, and use "sudo nano" to edit /etc/apt/sources.list. After installing xserver-xorg-video-intel, restart the computer with "sudo reboot".
