I recently upgraded from 10.04-11.04 using the 11.04 CD
I don't use any effects, I log on the sessions using Ubuntu classic (no effects) . Whenever I try to play a video, the gdm restarts and puts me back at the login screen. I installed vlc thinking it might help but no deal. Can anyone help me solve this? Thanks a lot.
*edit* I tried all different types of video outputs in vlc, the default seems to work the best, but as soon as I click the vlc window, try to resize it, or access any menu on vlc or try to fullscreen the video gdm crashes and restarts.
