The problem was that /etc/modules did not contain 'radeon'. After adding that and rebooting everything worked. I also tried 'modprobe radeon' while running X.

I cannot tell if the kernel upgrade to 2.6.36 was necessary. /Ole _______________________________________________ xorg@lists.freedesktop.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.freedesktop.org/mailman/listinfo/xorg Your subscription address: arch...@mail-archive.com
