Blue squares instead of video...
Problem: Occassionally the card will get into a mode where all video (mplayer, xine. Some non-straight X overlay thing) no longer works. Instead of the movie, I get a big blue screen.
Once this happens, I have to kill X to fix it.
I used to have this problem a bit more frequently in the 3xxx series of Linux drivers, but it had gone away. I recently added a bttv-based HD tuner card to my system, and when I try and use that card it will sometimes get into this mode.
The software for that card is rather unstable (and trying to use the motion comp/IDCT support), so I suspect that its doing something wrong... but I still think the driver should prevent things from becoming broken like this.
Any suggestions? Any thing I can do to better track this down?
