[systemd-devel] Multiseat session creation fail, VT number not 0

[Matthew Monaco]

I was having trouble getting a session on seat1 with v208, so I moved to git
which has a nicer error message than EINVAL:

pam_systemd(lightdm:session): Asking logind to create session: uid=1000 pid=637
service=lightdm type=x11 class=user seat=seat1 vtnr=2 tty= display=:1 remote=no
remote_user= remote_host=

pam_systemd(lightdm:session): Failed to create session: Seat has no VTs but VT
number not 0

I'm using lightdm 1.8.5. My X servers are

/usr/sbin/X :0 -config xorg-seat0.conf -seat seat0 -auth /run/lightdm/root/:0
-nolisten tcp vt1 -novtswitch

/usr/sbin/X -sharevts :1 -config xorg-seat1.conf -seat seat1 -auth
/run/lightdm/root/:1 -nolisten tcp vt2 -novtswitch

(I have no problems with seat0).

This same setup used to work with systemd ~v205, but I have used multiseat in a
while do to a move.

So, I don't understand where the failure is. Is lightdm starting X on the wrong
vt? Why is vt2/tty2 not allowed for a second seat?
