[plug] X over digital projecter

[sol]

Hey ho,

Next month I've been asked to give a public workshop/lecture on linux (basic 
stuff for complete newbies) in a public library. I've been assured that there 
will be a digital projector on site which I can plug my pc into to display my 
video output. I have a similar kind of presentation the week after for 
university requiring the use of a projector.

I've not used a digitial projecter before, and thought I'd better ask about 
it before making myself look like a dick in public. I was wondering whether 
I'll need to reset XF86Config for the specific resolution of the projector or 
whether the projector will just work out what resolution I'm running at and 
display everything on the desktop in screen? If I do need to change 
XF86Config settings, should I just change the monitor settings as if the 
projecter were just like a monitor device? Are there any other gotchas to 
keep in mind when using digital projectors?

ta in advance,
sol
