I have dual monitor setup, one widescreen LCD and an older CRT. Trying to
get different default modes on the two screens appears impossible. The CRT
does apparently not specify a preferred mode in its EDID, and without any
setting in xorg.conf it runs at the same 1680x1050 resolution as the LCD.

Trying to add an Option PreferredMode to its Monitor section in xorg.conf
resulted in the LCD also running at (the specified) 1280x1024. Adding an
Option PreferredMode to the LCD Monitor section had no effect (it still
ran at 1280x1024).

xrandr however, shows the + in the proper place for both monitors, so
at least something is picking up the PreferredMode, it's just not properly
applied when the initial mode is selected.

reassign 462562 xserver-xorg-core
kthxbye

I think this is because it tries to come up in the same resolution on
all connected displays by default, but I agree some way to override this
might be nice.

However, this is handled by the X server itself, reassigning.

I had a bug like this with earlier xserver-xorg-core. The BIOS
PreferredMode of the first output was overriding the xorg.conf
PreferredMode of the next output. Since VGA-0 is listed before DVI-0
with the ati driver, there's a good chance it's related and that the fix
for my bug was actually incomplete.

Can you send the corresponding xrandr output? I will forward your report
on the upstream bugzilla.

This does indeed sounds quite similar. If you have some pointers to where
in the code I should look, I'll see if I can figure out what's going on.
