65 I may be wrong but I think this is not quite correct. I had to look for
66 the specs (hsync, vsync) of my LCD because X was trying to run it on
67 higher refresh rates resulting in out of range errors. On the other hand
68 Colleen said the screen was "garbled" - doesn't seem to be an out of
69 range problem. Probably it would be best if Colleen attached or linked
70 to Xorg.0.log and xorg.conf and maybe kernel output [if that kernel
71 recompilation didn't fix the problems of course].
