Hi all a small consolidation of a problem that I've been having with the
Matrox G400 and dfbmga driver.
When playing the dfbmga output from mplayer I was getting this
http://www.linuxowl.com/images/screenshot-1.jpg when playing a video
file, thanks to Ville Syrjälä who said that he got something similar
when that framebuffer on the primary head was 1024x768 and when playing
the video with 1600x1200 it played fine.
BTW I found the reason for this. matroxfb was messing with CRTC1 high
priority request settings. The attached patch makes my TV-out happy :)
Mine *TOO*. No more fuss.
Thanks Ville, that's terrific.
