External monitors/projector

[Par Leijonhufvud]

I have a IBM Thinkpad R50e with 5.3 and x-org. Sometimes I want to  use
a projector as a secondary monitor (mostly with beamer style
presentations). I haven't been able to find any good pointers on how to
get it to use the external monitor/projector properly. Any suggestions?

Ideal would be having the option of either have the screen and the
external monitor/projector show the same things _or_ being treated as
separate entities...
