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 install xserver-xorg-video-intel-2.4
Now you should be set. Restart X and see if the graphics performance from intrepid is restored.
== 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".

[8086:27a2] (rev 03) |
Performance restored |
siretart |
compiz/3d performance is comparable to intrepid, even planet-penguin-racer is playable again |
[8086:2a42] (rev 07) |
Performance improved |
Lure |
much better performance than 2.6 driver with EXA+greedy or UXA, only problem is that it gets physical size of my 12.1" panel wrong (have to use xrandr --fbmm to fix it manually) |
[8086:2a02] (rev 03) |
Slightly worse |
Laurent |
With the normal Jaunty driver, at least with no open Windows, the Compiz effects were fluid. Now, I experiment lack of performances even with no open windows. Apart of that, no change (even after reboot). |
