Bug Description
Binary package hint: xserver-
After a apt-get dist-upgrade to jaunty I've got performance problems watching DVB-T video with kaffeine. Xorg and kaffeine both use 49% CPU performance. The picture in kaffeine jumps backward and forward (like a DJ scratching with vinyl LPs).
So I tried to set Option "AccelMethod" "uxa", but screens keep black after reboot. The cursor is still there and it's still possible to login and start kaffeine with alt-F2 keystroke (I hear the sound from DVB-T video).
Setting back Option to "AccelMethod" "exa", screens work, but performance problems keep the same.

For Karmic we're making UXA bugs like these a top priority, so I would like to forward this one upstream. First though, we need to verify the issue still exists with the latest upstream release. Would you please install and test the 2.7.0 driver and reproduce the bug, and let us know ASAP? A PPA with a Jaunty version of this driver is available at: https:/ /edge.launchpad .net/~ubuntu- x-swat/ +archive/ x-updates/
