[CentOS] Configure an ATI Radeon X1200 card?

 IMO I think you would be better off get the drivers from ATI and use them.
I have had better results with getting the propriatery drivers for those
cards. Nvidia drivers come with a graphical X configuration utility after
you build the kernel module driver.

Optionaly you can run "system-config-display" with the deafault configured X
config and select the ati card. Also if this is a duel monitor output card,
that could be where your ((NO Screens Are Found)) Error. Post your
Xorg.config file.
