If I use X on an accelerated, normal Matrox screen, my monitor complains on exit:
fH 49.4 KHz, fV 39.8 Hz
(and it doesn't sync at 40 Hz vertical refresh :-( ).
This is _half_ of the normal 80 Hz. Using fbset -a "1600x1200-80" before X, of after X, doesn't do anything. Does anybody know what to hack out in X to get it to _not_ reset my G400 to some unusable state? 3.3.6 was didn't do this. I can use the framebuffer-screen just fine, but I miss the DGA extension.
Thanks, Jurriaan -- BOFH excuse #329:
