Ah, yes - I should have mentioned I know about this. It is a hack and it has problems: - It only works for some VGA's - nVidia with their closed drivers (not with XFree's drivers) and Matrox are the only ones that I am aware of. - Even with the nVidia's (don't know about Matrox), the computer hangs totally when switching modes (to console, to vmware's fullscreen... but not ctrl+alt+plus). - I wasn't able to make the USB keyboard work in XFree 4.2.0 (works in 4.1.0), but that may be some small issue... - And, as I said, it's an ugly hack. When it works, fine, but sometimes it does not and even causes crashes and hangs. I am sure the XFree developers wouldn't agree to integrate this in an official release. The patch does nothing to serialize accesses by the multiple servers to the VGA's... It _has_ to crash, sooner or later. :-) Are there really no plans to provide such multi-user functionality in XFree? It seems to me like a natural way to go and one that has been much requested... I would gladly donate my time for this if someone of the XFree developers provided some guidance and advice. I've already spent some hours looking at the source and it's still a jungle to me... (No offence intended, of course. It's probably just me.) The way I see is providing multiple event queues, one for each user (=screen, or even set of screens), and attach one keyboard and one mouse to each queue. And make one mouse cursor for each queue. I'm probably missing something important, but on first view, that seems to be it. Any insight?
