If you are using the latest version of xserver-xorg, then the command
xrandr should be able to do what you want.  Here is an example that
shuts off my internal display, 

xrandr --output VGA --mode 1024x768  --output LVDS --off

and here is one that binds the two displays together into one screen

xrandr --output VGA --mode 1600x1200 --output LVDS --left-of VGA --mode 1024x768

I guess you probably want something like 

xrandr --output VGA --off

you can find out the names of your displays by xrandr with no options.

I am using debian xserver-xorg 1:7.2-5 (X.Org version 1.3.0)
