Bug Description
As long as LightDM gains support to logind's automatic multiseat feature (https:/
Currently in X.Org, the only way to do such a thing is launching a bare (no greeter) X server spanning all available monitors, on top of which one launches nested X servers (usually Xephyr instances), one for each seat.
Maybe I should open this bug in LightDM page, but I'm opening it here because I wonder if Mir could support this feature without the need of nested servers.

I don't know if we have the same problem. Look this scenary:
Session130:
realname = 'name of the user 1'
x11-display = ':2'
is-local = TRUE
Session163:
realname = 'Light Display Manager'
x11-display = ':4'
is-local = TRUE
Session162:
realname = 'name of the user 2'
x11-display = '10.0.0.4:1'
is-local = FALSE
The session 162 is a Xming connection from a notebook at local net.
The session 130 is a Unity-2D session from local seat (beside the CPU).
The session 163 was the local seat of an "user 3" who closed his Unity session.
There aren't x11-display :0 or :1 because they were Unity sessions (local) that were closed.
Attention! If the user 1 close his session, the local monitor turns blank and the machine (local keyboard and mouse) inoperable. It returns to normal (rekindling the local monitor with a "Light Display Manager" on tty7) only if I execute a "sudo service lightdm restart" via SSH, losing all sessions graphic.
