With today's auto-config, and not reading xorg.conf, I don't know.
But you used to be able to set a desktop size distinct from the
actual display size. Then the display could be panned around the
virtual desktop space.
On the system I'm using I have an nVidia graphics card. It has
a binary to set some of the card properties. Among them is "enable
panning" and the a field to set the virtual display size. It worked.
So this seems to be using the hardware to do what I recall doing in
the X-window or display manager software.
