Hi Kevin,

If you are talking about the ability to pan around the screen, then yes,
there is a "virtual" option that you can add to your Display subsection
that will allow you to specify a virtual resolution that is larger than
your video mode.  For example, to set your video mode to 1024x768 and
your virtual screen size to 1600x1200, you could do the following:

Section "Screen"
        Identifier "Screen0"
        Device     "Videocard0"
        Monitor    "Monitor0"
        DefaultDepth     24
        SubSection "Display"
                Viewport   0 0
                Depth     24
                Modes    "1024x768"
                Virtual  1600 1200
        EndSubSection
EndSection

Then, when you restart the X server, your monitor will show a 1024x768
subset of the larger 1600x1200 virtual screen.  You can use the mouse to
pan that subset across the entire virtual screen.
