i have been using these sites as a tutorial on installing my ATI drivers
I used the newest drivers ati-driver-installer-8-9-x86.x86_64.run
with an ATI radeon mobilty x600 card.
I didn't have compiz-fuzion installed oddly enough, but I finally installed it an now see "custom" in my visual effects screen. But now io cant open AT Catalyst Control Center because it says there was a problem initializing it saying "No ATI graphics driver installed or the ATI driver is not functioning properly"
Before I had compiz installed, this was working just fine... siiggh
