It does 70% constant CPU load.

I searched and tried to solve it many ways but neither of the ideas worked.
- switching to an older kernel
- boot with noacpi option
- disable composite module
- reconfigure the xorg
- etc...

Make sure you don't have a browser running, does it still use cpu?

I did not have browser running but now it changed. It does not use this much cpu all the time but when I start the gnome system monitor it uses up 70% again.

I saw the same bug in my clean Hardy installation. No external repositories activated. Everithing is OK at start, but in half an hour, xorg process grows up...
I have no ATI driver, just ubuntu-restricted extras, japanese support, emesene, ccsm and awn installed after OS clean install.
AMD Athlon XP 2600+
ATI Radeon 9250
1 GB RAM

Future updates will correct it? Could it be FF beta 5 caused by?
