I wanted to setup a game (Cube) on my CentOS box. I noticed the game runs very low on fps and I assumed that was because there was no video acceleration. So I downloaded the ATI driver package: ati-driver-installer-8.23.7-i386.run (31Mb). Everything went fine with the setup, and now the game works well on fps however X seems to be running on a huge resolution (I believe its 1600x1200, which is much bigger than my usual 1024x768 - also the screen refresh rate is so low that it hurts my eyes). I am however unable to revert back to my original resolution because:
-
Applications -> System Settings -> Display no longer works (it just doesn't start).
- I've got an
ATI Control utility but there is nothing about screen resolution there.
- the command
aticonfig --resolution=1024x768 seems to be working (of course I ran that as root), but after I restart X (or reboot) the resolution stays the same (huge).
- tried editing xorg.conf, but still no luck. Below is a section which I consider relevant from xorg.conf:
Code:

VendorName "Monitor Vendor"

What options do I have left ?
PS: My display adapter is an ATI Radeon 9800 SE
PPS: I edited the line
Code:
DisplaySize 1024 768
from the above xorg.conf. It was originally set up to:
Code:
DisplaySize 320 240
