Actually, Xrandr 1.2 is supported by the free xorg-radeon-driver. But why doesn't it work? I could not find anything in the logs. If I try it without Xrandr I get this strange error that the Display Manager still thinks it is in 640x480 and the display is at 1280x1024 and the user did not set a change of e screen resolution.

Maybe I'll try to use Xrandr manually. Any suggestions where to look further? Thanks.
