Package: lightdm
Version: 1.18.3-1
Severity: important
Multi-seat works perfectly up to the point which I decribe below.
There are existing users who do not login who automatically appear to
login onto the workstation.
(no remote services -- it's not a compromised system)
loginctl
SESSION UID USER SEAT TTY
14518 0 root
8901 1000 userA seat0
c14 131 lightdm seat0
c33 131 lightdm seat-1
Even after clearing the logged-in users (there's only about 2 or 3 users
on this system.. ) , with loginctl terminate-user ... a user or two
then re-appear again...
ps shows gvfs things.
I looked at timers with systemctl list-timers and disabled/stopped any
of them.
I also tried to look at timers with user accounts using, "systemctl
--user" list-timers and couldn't find anything under there.
I wonder what is "triggering" these processes...
it must be a bug lightdm.
/etc/lightdm/lightdm.conf
----------------
[Seat:seat0]
logind-check-graphical=true
type=xlocal
#xserver-config=/etc/X11/xorg.conf.intel_seat0
#note: debian's current Xorg (in this system), manpage does not indicate
-seat seat_id but Xorg --help shows it is available
xserver-config=/etc/X11/xorg.conf.seat0
xserver-command=/usr/bin/Xorg -nolisten tcp -layout layout_seat0 -seat
seat0 -novtswitch
[Seat:seat-1]
logind-check-graphical=true
type=xlocal
xserver-config=/etc/X11/xorg.conf.seat-1
xserver-command=/usr/bin/Xorg -nolisten tcp -layout layout_seat-1 -seat
seat-1 -novtswitch
-------------
I provided xserver-config for the two seats, there's nothing special I
can find which can be triggering this...
Despite the multiple ghost-logins, I am able to login via lightdm with
the already listed users shown with loginctl list-users.
