How do you know the projector will like 1024x768? Everywhere you go,
they have a different projector or giant TV screen, and they all have
their own favorite geometry.

Will the preceding commands give you video on both the laptop and the
projector? If so, will either one have its screen truncated? It's been
years since I could get a good, solid picture on both my laptop and the
projector.

In my typical presentation at Bar Camp Orlando, the guy before me runs
late, consumes all the 10 minute guardband between our talks, and 2
minutes before I'm scheduled to talk, I walk up, apologize, switch our
computers, run my lxrandr, and start my presentation while he's still
talking. LOL, within 2 minutes of the start of the guardband after my
talk, I'm torn down, ready for the next guy to hook up, I've
surrendered any microphone, and I'm off to the side answering
questions, slowly migrating out into the hall so the next guys starts
on time.
