Two screens, two kbds, two users ?...

Greetings. Given a PC with two video outlets, is it possible to
plug two keyboards in (e.g. 2 usb keyboards) and associate each
keyboard with its particular screen in such a way that two users
can log in ?

Regards, Peter

We have a Userful station at the local library - four seats hosted from
one tower. See userful.ca - I believe you can dowload the software.

Here's an article about doing six of them at once:

Note the comments under "Problems:" near the end of the
article.

Looks like you can download a 2-user version...

Excellent link Smile Also linked to from there:
http://blog.chris.tylers.info/index.php?/archives/14-Multiseat-X-Under-X11R6.97.0.html

The problem ("While the system worked very well, it was extremely
unstable. In particular, we got a kernel oops fairly often when we
logged out.") looks like it might be intractable, since they tried
fvwm and xdm as well as gnome. Their approach (xorg.conf and
[gx]dm.conf) should port to *BSD too, so that might also be worth
a try... I mean, just as an experiment, of course ...

It also raises the related off-topic question about logging in
multiuser at the getty level. Getty, and AKAICS the tty driver
assume a bidirectional /dev/ttyXX device, so I'm also trying to
work out what pairs off kbds and screens into /dev/ttyXX devices.

Hoping to rediscover multiuser computing, Regards, Peter
