Xorg log with KMS enabled
I am having a problem with video playback on Ubuntu 12.04. When I try to play a
video with resolution 640x480 (or similar) it either hangs or flickers like
hell (depends on the player I use, VLC hangs).
All players are using the Xvideo extension for output by default, but this
seems to have a problem. The playback gets better when I configure the players
to use x11 output instead (some frames are dropped though, because I have a
slow CPU).
But if I boot with "nomodeset", which disables KMS, I can use the Xvideo
output, the playback works smoothly then. So I assume there is a bug somewhere
in the combination of Xvideo + KMS + radeon driver (at least for my hardware).</pre>
