@ReedMace, that command resets your configuration file to the same
config that you'd get if you installed X.org cleanly today. The config
file you had before had some commented out junk in it left from an
upgrade (which wasn't harmful but ugly) and also a restrictive virtual
size that most likely caused your issue.

@Geir, my thinking here was, hmm "two black stripes" sounds like a 4:3
running in a 16:10 and I thought, if he has a 16:10 he probably didn't
want that 1024x768 virtual size in there. Why would anyone even want a
virtual size that small anyway? I thought that was used for dual-head
configs only (I'm not sure what exactly virtual size is though)?

The question remains of course, why did he have that virtual size in
there? Maybe it was added manually (config issue) or it could have been
added by gnome-display-properties when the driver was operating in some
really strange low-res mode or something? Unless ReedMace repro's with
live CD I think we should just close this bug as a one off config issue.

FWIW; just for fun I slapped a 1024x768 virtual size on my 965GM laptop
just now (it normally runs 1280x800 on the LVDS). I was expecting it to
boot 1024x768 with "two black stripes" (confirming my longshot guess
above) but it didn't actually; on my system it oddly booted into
640x400, even though xrandr lists several supports modes up to 1024x768
as the highest. I totally don't get how or why the X server came up with
that res. Interesting note about debconf vs missing xorg.conf btw ...
