Enabling compiz for X3100 graphic card

If you install Ubuntu on a PC with a X3100 (aka 965), the right driver will be in place. So don't do as I did ;-) trying to upgrade the driver or editing the xorg.conf to see what it going on...
The reason why it is not working out of the box is because it is meant that way. Developers have black listed the x3100 due to some limitation to the with the current intel driver. So if you want compiz, you have to take the X3100 out of the black list. To do so, edit the file /usr/bin/compiz and comment out (add a # sign at the beginning) the following line :

T=”$T 8086:2982 8086:2992 8086:29a2 8086:2a02 8086:2a12″ # intel 965

So, in the end it should look like this:

#T=”$T 8086:2982 8086:2992 8086:29a2 8086:2a02 8086:2a12″ # intel 965

Then you can go to system->preferences->appearance and click on the "Visual Effect" tab to enable compiz. It worked like a charm for me (Toshiba A200 FT-1).
