Package: gdm3
Version: 3.12.2-4
Followup-For: Bug #760366

Dear Maintainer,

same problem here.

Since updating from gdm3 3.8.4-9 on the 3rd of September to 3.12.x there is no 
login-mask. I do have the debian-logo on both displays. On the main display I
have the top-bar. It shows the day and time in the center and the symbols for 
accessibility, languge and LAN-speaker-shutdown. When opening the right-most 
dropdown i can adjust the volume, I see entries for wired and location and I 
have the shutdown-button (and it works). But I cannot log in.

dmesg shows following messages:
systemd-logind[2640]: Failed to start unit user at 1000.service: Unknown unit: user at 1000.service
systemd-logind[2640]: Failed to start user service: Unknown unit: user at 1000.service
systemd-logind[2640]: New session 1 of user mots.
systemd-logind[2640]: Failed to start unit user at 0.service: Unknown unit: user at 0.service
systemd-logind[2640]: Failed to start user service: Unknown unit: user at 0.service
systemd-logind[2640]: New session 3 of user root.

I found bug #724731:
As suggested I checked libpam-systemd, it is installed.
When switching to lightdm, as a workaround, I can login and everything seems 
to work (gnome3). But I would like to use gdm3.

Updating to gdm3 3.12.2-4 (unstable) as reportbug suggested did not help.

If I have to provide more details, I will gladly do.
