Ctrl+Alt+KpPlus/Ctrl+Alt+KpMinus (ie. Plus key on the right edge of
the keyboard) change video mode, if more than one is defined. You can
change the default mode by rearranging the first "Modes" line in the
"screen" section of /etc/X11/XF86Config with the Driver line
corresponding to your server. The first is the default, KpPlus cycles
forward in the list, and KpMinus backwards.
ie. If you have the XF86_SVGA server installed, you use screen section
with a 'Driver "svga"' line in it.
If you want to create more modes, I found the file
/usr/lib/X11/doc/VideoModes.doc useful, and it seems to be safe
provided you told xf86config (in the xbase install in debian 0.96R6)
the correct hsync and vsync frequencies for your monitor. (Get ready
for Ctrl+Alt+Backspace if not. :-) More details in the XF86Config man
page if you feel brave.
