How to Enable UXA at Ubuntu Jaunty

Hey guys, i upgraded to ubuntu jaunty today.I have a Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller card and after upgrading to Ubuntu Jaunty i had a lot of compiz problems and low frame rate problems.Xorg's cpu usage does not go under %20 even i disable compiz.Yup shit.Then i found UXA.Every problems are fixed with this, my ubuntu jaunty box is flying now : ) .Please read all of my blog post before doing anything here because UXA is VERY VERY unstable and it is not going to ship with Ubuntu Jaunty since it is not stable.Before doing anything enter this command :

$lspci -nn | grep VGA

The output will look like :

nyn@nyn-laptop:~$ lspci -nn | grep VGA
00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller [8086:2a02] (rev 03)

Note that number between [] (at my case it is 8086:2a02 )

Now go here , and check the reports which are made by people (It is working perfect with my card, however i did not test suspend etc).If the reports for your card is ok (Even it is not ok, you can test it yourself since it is very easy to revert the changes), let's begin :

Edit your xorg.conf file and add
Option "AccelMethod" "uxa"
below
Identifier "Configured Video Device"

It should look like this :

Section "Device"
Identifier "Configured Video Device"
# ...
Option "AccelMethod" "uxa"
EndSection

After this reboot your Ubuntu Jaunty box and test it.If something goes wrong and you want to revert back, just put a comment (#) at Option line we added or just remove that line.
