View Full Version : ati graphics problem on 11.04

October 10th, 2011, 11:37 AM
I have an ati radeon 9550. I have used it successfully on earlier versions of mythbuntu. On this one I just can't get it working at decent speed (HD playback is very jerky.

I seem to have the "race"issue discussed here https://wiki.ubuntu.com/X/KernelModeSetting

my kern.log says that modesetting is enabled, but xorg.0.log says it isn't. I have tried adding "modprobe radeon" into /etc/init/gdm.conf as recommended, but with no result.

Help please.
