Re: Projector Wall
Right. I have considered trying to modify Compiz to perhaps draw onto a quad for each screen, and then transform those. I don't really want to dive into that though if perhaps trimming is possible in an easier place or someone has a transform idea that I have not found.
I've gotten Compiz running on my configuration using Xgl actually, but Xgl is deprecated now. I haven't really tried to coerce Xgl to run on a newer release of X.org -- is it worth my time to try, or is it too intimately concerned with the host X server?
