I see this problem as well, but not 100% of the time. It seems that I can get usable 3D performance with KMS if I reboot with radeon.modeset=0, select "Normal" for Visual Effects, then reboot again with radeon.modeset=1. It's still not great compared to when KMS is disabled but much better than if I boot with KMS enabled then start compiz after logging in.
I have been able to use this workaround twice now after running in the slow desktop problem. -- [KMS][RV530] compiz very slow on AGP hardware https://bugs.launchpad.net/bugs/496653 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
