you don't even have to restart the X server.  Just use xrandr.  some examples:
# turn vga output off
xrandr --output VGA-0 --off
# move vga output right of LVDS output
xrandr --output VGA-0 -right-of LVDS
# switch the mode on DVI to 1280x1024
xrandr --output DVI-0 --mode 1280x1024
# automatically set up all connected outputs
xrandr --auto

by default xrandr will turn on all outputs with monitors detected.
you can turn off any outputs you don't want on.  the desktop will
automatically resize to the size of the largest active output.
