The reason for the fullscreen video performance hit seems to be no XV overlay support w/ KMS turned on. Furthermore, as of xserver-xorg-video- ati 6.13.0-1ubuntu2, XV has been explicitly and completely disabled on my machine (which I believe to be a mistake, bug #562537).
Temporary workaround (for me) so as to have desktop effects and accelerated fullscreen video: Install the jaunty version of libgl1-mesa-dri and libgl1-mesa-glx (7.4-0ubuntu3.2). Install xserver-xorg-video-ati and xserver-xorg-video-radeon version 6.13.0-1ubuntu1 (available via launchpad at https://launchpad.net/ubuntu/lucid/i386/xserver-xorg-video-radeon/1:6.13.0-1ubuntu1 and https://launchpad.net/ubuntu/lucid/i386/xserver-xorg-video-ati/1:6.13.0-1ubuntu1) Obviously, I would prefer not to use these outdated packages, but it's the only way I know of to avoid these regressions. Hopefully XV overlay support will come to KMS soon. -- [RV100/RV200] (Needs KMS) Background and full screen apps don't show up when Normal Visual Effects on https://bugs.launchpad.net/bugs/444139 You received this bug notification because you are a member of Ubuntu-X, which is the registrant for xserver-xorg-driver-ati. _______________________________________________ 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
