For me, the following incantation works:

xrandr --output LVDS --auto --output VGA --same-as LVDS --auto

both with an external monitor and a projector.  In the latter case,
where the projector's resolution is 1024x768, the note's screen is
shrunk to a 1024x768 rectangle, and the resulting margins are still
useful, even though they are not projected.  Unplugging the projector,
the same command restores the screen to the original 1600x900. A funny
side effect: the gnome top panel comes out completely scrambled.
