Xorg often overrides the Fn + F4 switching of the BIOS. Depending on
your video card, one or more of the following might work:

1) For some cards there is a command available to switch LCD and
   external video on and off. Using ACPI and a bit of scripting you can
   even assign this to special keys.

2) Sometimes Xorg can be tricked by switching to a tty and using the Fn
   + F4 combination there. Then you have to restart X without switching
   back to the CTRL + ALT + F7 terminal, for example by running
   /etc/init.d/gdm restart

3) Sometimes it is necessary to write a special xorg.conf for a cloned
   dual display setup and start X with that layout, e.g.
   startx -- -layout Beamer
   (assuming that you called this layout "Beamer" in xorg.conf.)

If you post more info about your video card ("lspci | grep -i vga") it
is very likely that someone will be able to give you more specific
advice.
