It is. Last time I looked into it it worked but wasn't especially stable... ie if user B logged out, then user A's X session was also killed while the login manager restarted.

USB because they can each be identified individually, likewise for the GFX cards. Once the devices can be uniquely identified, you can set up X to have specific keyboard, mouse and GFX card as a single X session, and the other keyboard/mouse/GFX card as a different X session. > You might make it work by using some sort of virtualisation and > giving each host access to it's own graphics/keboard/mouse.

Sounds like overkill. :D > Can't say it's a project that enthuses me though :) I tried it a few years back with my BTEC students. It was fun, but a bit over their heads I think. Might try it again soon. :) Grant. -- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/listfaq
