I have the same problem. X Server fails continuously. Every time I try to see a movie, rmvb, flv, mkv, whatever, even on Totem when I'm playing music and I try to change the sound volume. I can't see videos, every time I try to put a video on full screen, x server fails and I'm back on log in screen. So I can reproduce the bug all the time, also with vlc, if I try to maximize the window while playing a video X Server fails again.
Ubuntu 11.04 stable. I log in with "Ubuntu Classic". I have no graphics hardware acceleration. I installed Ubuntu on a clean partition.
