99 times out of 100, LCD screens do just fine with a minimal xorg.conf.
Here's mine:

### Available Driver options are:-

Notice how the only things that are uncommented are unky radeon driver
settings. I can even take the "Modes" line out and it all still works
just fine. That's because virtually all modern monitors/cards speak DDC
and Xorg can ask the hardware when it starts what the hardware
supports.
The only thing Colleen *has* to customize here is the correct "Driver"
for her nvdia card

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