I'm using Debian on a Matrox card. Matrox Graphics, Inc. G400 rev 133, Package: xserver-xorg-video-mga Version: 1:1.4.4.dfsg.1-2 Playing a video on a mga multihead/xinerama setup is working without problems (using X11/xv). After suspending the system (kernel suspend) and resuming the only output on the screen is a blue box. I tried resetting the colorkey with xvattr -a XV_COLORKEY -v 66046 but it didn't helped. Logging out of the X session and logging in again solves the problem.
Created attachment 8503 [details] Xorg Configuration of the affected system
The video overlay need to be re-initialized when the computer is resumed. Many drivers only initialize the overlay when the server is started.
Sorry about the phenomenal bug spam, guys. Adding xorg-team@ to the QA contact so bugs don't get lost in future.
