I had a devil of a time getting X right on a test machine (K6-2 500 with
an old Radeon 7000 card and a 17" no-name monitor). Once I got it
running, it's needed no more care from me. But it drive me nuts since
the only mode(s) that worked reliably for me was 800x600 (or 640 x 480).
Now its happily buzzing along (when I boot it) at 1280x1024.
I had an easier time exchanging a Spectre 17" tube for an Acer 22" flat
panel on F8 (GeForce 6200), and the 19" Dell monitor worked right away
on the F11 test system I built (nVidia Riva TNT).
They changed the default behavior of Xorg when the monitor responds
correctly to queries about its capabilities, making Xorg.conf less
useful, and more difficult to use to override things. I think that was
for F10....
Anyways its bedtime for me now....
