16 Hmmm. If you try a slightly lower-resolution mode (say the 1600x1200 you
17 tried earlier), or the same mode with a lower refresh rate (50Hz
18 maybe?), does that work? The other OS's could be cheating their refresh
19 rate a bit. Also, do you have the manual for your monitor? That may have
20 details on the precise numbers. You could verify that the vertical
21 refresh and horizontal rates are correctly detected, or specify them
22 manually in xorg.conf.

24 Thanks,
