Well, it certainly is the name of
someone's video card!!!
The two standard drivers for ATI are "ati" and "radeon". Both should be available in Fedora 8. First, look in /etc/X11/xorg.conf to see what you are using now. You are looking for something like this:
Code:
Section "Device"
Identifier "device1"
VendorName "ATI Technologies Inc."
BoardName "ATI Radeon"
Driver "radeon"
EndSection
All this aside, I am not clear on how the choice of video driver would cause the CPU to be running excessively. Is the system otherwise running normally?
