Do I understand correctly that, when connecting through a KVM, the
system drops the monitor resolution to nothing with the same xorg.conf
file?

What's actually happening? Is xorg thinking that a new monitor has been
connected (as the monitor is invisible through the KVM), looks for a
new/default monitor setting, doesn't find one, and defaults to least
common denominator? Not necessarly a bad defensive strategy, you could
have connected a 20 year old clunker which would let the smoke out if
xorg was running it at 1600x1200.

Rather than entering modelines manually, you'd be faster to enter the
monitor's actual hsync/vsync rates manually, which your system tool
should also let you do at 640x480.

Perhaps it stored the monitor parameters for future use. If you
connected a small monitor, things might go belly-up. Which do you
prefer?
