you'll need to add a virtual line to your config set to the max size
desktop you want to use, e.g.,:

       Subsection "Display"
               Depth   24
               Virtual 2680 1050
               Modes   "1400x1050"
       EndSubSection

then

dualhead:
xrandr --output VGA-0 --right-of LVDS

turn vga port off:
xrandr --output VGA-0 --off

etc.  See xrandr --help for more.
