I like to use 'xrandr' to change resolution.

It's more like video card problem, if were monitor problem then wouldn't
start and didn't came back to login screen. Try with `vesa' as driver...
But I don't think that will solve your problem.

The relevant part from 'lspci -v' might be necessary if it's not a
config problem.

What GUI?

Do you have these specs in xorg.conf? Run

dpkg-reconfigure xserver-xorg

IIRC there are three ways to set monitor specs. You might need to
use the 'advanced' method. Also be sure to select (with space-bar)
all resolutions you want to be able to use.

If the reconfiguring fails then you should post the output of lspci
suggested above, your xorg.conf and Xorg.0.log (the log preferably on
some site because it can be quite long).

HTH,
Andrei
