Description:
Using X on Arch Linux results in very high CPU usage, which leaves my system almost unusable, since even simple tasks, like scrolling or selecting files, are inhumanly slow :-D.

I've got KMS enabled (since you can't start X without with in the newer intel drivers), using KDE(mod) (but I had the same X behaviour with KDE 4.3.5 from [extra]) and KWin compositing is disabled.
I've got no xorg.conf.

Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 03)

xorg-server: 1.7.5.902-1
xf86-video-intel: 2.10.0-1
mesa: 7.7.1-0.1
kernel26: 2.6.32.10-1

I was encountering this problem also with older versions of the above mentioned packages.

Interestingly enough, I do not have this issue when running sidux, which I am running on the same hardware, with almost the same package versions of the mentioned packages above. (Only big difference: Sidux offers Qt 4.5.2 and KDE 4.3.4, while Arch Linux/KDEmod offer 4.6.x with 4.4.2, but the problem I described also was there with KDE 4.3.5 from [extra]).

There must be going something wrong...
This task depends upon

I now have a new notebook with a nvidia graphics card, so I cannot test it anymore… The CPU usage with the nvidia binary driver is pretty normal though
