Hi Pete.  When you say that you're switching your screen size, how
exactly are you doing that?  Are you using the xrandr command or are
you using Ctrl-Alt-+ and Ctrl-Alt--?  The second way only changes your
viewport size and your desktop will always remain the same size, but
using the xrandr allows you to actually change the size of your desktop.
Assuming you're not already using xrandr, type "xrandr" to get a summary
of the available resolutions, then do

    xrandr -s 320x200

to switch.

I believe (although I haven't used it enough to say for sure) that you
don't need to list the resolutions you want to use in your xorg.conf
file.  Those are only necessary for changing between viewport sizes with
Ctrl-Alt-{+/-}.

Hope that helps.


Matt
