Let's see what the other options are:
According to http://wiki.x.org/wiki/Development/Documentation/Multiseat
we have the following pages with "Users" in mind:
mdm is a nice "feature preview", even with a live CD, but just no major
distro ships it. And if a major distro doesn't ship some software, it
just doesn't exist in a Linux world.
Livecd had some flaws as I tested it:
- resolutions were not detected properly and I couldn't change them
(even xrandr was showing that 1024x768 is the only possible one)
- the system didn't reboot as I told it to; it was hanging somewhere at
the end waiting for something.
These are minor flaws, and perhaps not even mdm related.
What I didn't like about mdm is that it doesn't ask if it should really
shut down or reboot the machine if there are other users logged in (for
example, KDM does that, it is nice IMO).
2) http://en.wikipedia.org/wiki/Multiseat - wikipedia article.
It's a good explanation, but it won't configure your Linux desktop to be
a multiseat station.
3) http://www.ltn.lv/~aivils/?proj_id=multiseat&menu_id=1 - as big fat
words say, "DONT TRY THIS!", so let's just not go there.
4) http://www.tldp.org/HOWTO/XFree-Local-multi-user-HOWTO/ - "very old
documentation. DONT TRY THIS! It is here just for historical purposes".
OK, so another antiquated documentation. I actually tried to read this,
well, but yes, I agree with "DONT TRY THIS" words now.
So what did we have there - nothing usable for a mere mortal, rather
scary words that multiseat should not be used.
Let's look here now:
It's far from being perfect, but at least:
- does not tell you you have to patch and compile your brand new 2.4
kernel, because otherwise, multiseat is not possible
- doesn't tell you to install a modified XFree86 server
- is easy to follow and will work for majority of users who ever edited
their xorg.conf in the past
So sorry, but if anything's confusing the poor users, it's that
wiki.x.org page that lists old documentation which is even not
Or did you mean, there is some other documentation listed elsewhere? I'd
be glad to hear about it.
Of course, the whole discussion would be unnecessary if the distros
shipped a tool - other than a text editor - for configuring multiseat;
but so far, I don't know any distro that does (despite numerous user
requests; perhaps not enough though).
