Bug#932047: lightdm: greeter session support for elogind

[Fabian Schaar <fabian-schaar@gmx.de>]

Hey there,

I highly agree with Mark on this suggestion, since I ran into the exact
same problem after the installation of an alternative init system on
Debian Bullseye via the chroot method using d-i (first sysvinit, then
OpenRC). After adding the proposed line to /etc/pam.d/lightdm-greeter
(and commenting out the pam_systemd one), everything worked fine.

Best regards,
Fabian
