There's a (broken, incomplete, useful for reading but not for running, please don't even try to run it) version of this idea here: http://cgit.freedesktop.org/~ajax/xserver-shatter?h=shatter In case anyone's interested in the general shape of the idea. The comment at the top here is, well, more or less accurate: http://cgit.freedesktop.org/~ajax/xserver-shatter/tree/randr/rrmx.c?h=shatter&id=2d97ccc7ef20ab186dbe681fbe101ab4a246edfd The big work left to do is splitting this the rest of the way out from RANDR, redoing rendering dispatch so that everything is against contexts, probably some other stuff I'm forgetting. I've got a better writeup on the core API changes this will need, and a less garbage implementation, laying around on some laptop somewhere. I'll see about getting those uploaded. - ajax
