[ltp] external monitor Fn-F7

[David Tansey]

Has anyone setup a thinkpad to easily switch to external monitors and
back (both cloning, side-by-side, and one-or-the-other)?

I found a website with an xorg.conf file, but that put them side-by-side
and didn't like my laptop having a different resolution than my external
LCD. 

i'm trying i810switch, but am not having too much success. it says 
No LCD support for this chipset.

I have an x40 running ubuntu (hoary) with the intel i855 chipset. my
external monitor is a 17 inch LCD with 1280x1024 native resolution.
Ideally, I'd be able to switch to any external monitor (or projector.) 

I'd also love to map Fn-F7 to toggle between laptop,external,both, (and
if i'm lucky, cloning or side by side)

thank for the tips!
