I want to connect a second monitor, keyboard and mouse to my PC (running Ubuntu) and let somebody else (e.g. my son) use the a different TTY while I am working.

I know I can switch between TTYs using Alt+F[1-6], and that I could potentially start several X sessions (Alt+F[7-12]), but is it possible to use them at the same time with different I/O devices?

In a way I'd like to emulate the way computers used to work in the old days, when you'd have a central machine with several "terminals" attached. Linux (and Unix style OSs) are generally designed for that, so it should be possible, right?

There is a guide on Linux Gazette for a six-headed X11 system.

It works by giving a different ServerLayout in the xorg.conf, grouping the different screen, mouse, keyboard. Each screen has its own GDM instance/session.

  • This doesn't really answer the question beyond that it's possible. What are you not allowed to link to? – Anko May 2 '14 at 14:57

    @anko It tells "links to linux gazette are not allowed" – Emmanuel May 2 '14 at 14:58
  • That seems odd. I just edited with a link here and got no such message. (My edit in the review queue now.) – Anko May 2 '14 at 15:03
  • This is exactly what I was looking for. Thanks! – user2426172 May 2 '14 at 15:09
