That's right, ATI just sucks big timre on Linux.
Everybody should boycot their crap, claiming they are developing drivers for 64-bit and still nothing.
They SUCK!
I did some fiddling, for example dual head only works in xfree 4.3, but not the 1 in Suse 9.1.
I also had the drivers working on xorg 6.7 on gentoo. xorg 6.8 is no go at all!
Dual head on xorg gives a blurred 2nd screen by the way.
So if you want some decent graphics just buy Nvidia and tell all your friends to do the same
!
Nvidia has 64-bit drivers (for a long time), good tv-out support, dual head configuration and easy switching between resolutions, just look at the README.
Hope this helps some folks
