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.
