Did you be chance ever identify the issue? My main frontend started
doing the same thing yesterday - apparently also without a reason.
It's also a Zotac IONITX (A-E) but with Mythbuntu 11.04. I've never
seen the issue before, everything worked earlier in the day when I
suspended the system into S3 mode and left it. In the evening I woke
up the system, started live TV and got a black screen instead of the
video, but with sound, OSD and subtitles working fine. No software
updates has been accepted on the system for 1-2 weeks, so updated
drivers/Xorg/MythTV shouldn't be the cause - the system has also been
powered off multiple times during this week. Changing to a non-VDPAU
profile gets the picture back, but changing back to any of the
VDPAU-profiles bring back the issue. The issue remains after a hard
reset and after leaving the system overnight with no power supply
I found a setting in the BIOS called something like "Initialize VGA
BIOS when resuming from S3 mode", but it didn't make a difference.
Neither did disabling/enabling compositing in Xorg.
I haven't tried reinstalling the system yet, but that will probably be
the next step...it would however be nice to identify the issue.
