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.
Results
If you have tested the package, please report your findings (broken|same|better) and also your PCI ID:
lspci -nn | grep VGA

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) |
