I have ATI Radeon 9000 and the last version of xf86-video-ati 6.6.191-1 doesn't work or better: KDE start but on logoff computer freezing. Also when screensaver start and works correct but after move a mouse or press a key computer freezing. My system: Arch Linux, kernel 2.6.21, KDE 3.5.6, Xorg 70.200.000 Thank you. -- http://www.flickr.com/photos/starikarp
