Hi!
If you have started X (which I assume you have from your description), 
try fiddling with xrandr.  Just running xrandr without any arguments 
should show all screens connected to your computer.  You can then 
disable certain screens with
xrandr --output [name-of-output] --off
The name of the output is listed in the xrandr output from the first run.
Is this a dual or multi screen set up?

Regards
