[lug] Re: Another question on X. displaying at two resolutions simultaneously?

Have you looked at using something like VNC?  It would require another
computer but should do what you want, even if it is overkill.

You will always have a issue where the projector will not show a area
of the screen that that is visible to the laptop user.  This in it self
would probably make it more frustrating than just running the laptop at
a lower res.
