I was attempting to give a presentation at the local Linux User's Group yesterday evening, and I couldn't get my laptop to sync with the projector in the room. Today I tried with an external display at home. I was able to get it to work in Vista once I was logged in, but not in sidux. Any ideas?

I can throw my config on the pile in case it helps.  I'm using ati, and 
there's a program I have (not sure if it's from a repository) called 
aticonfig that will produce different X config files depending on what 
setup you want.  Here is an example of what's in mine:
