This looks wrong. I think it might be caused by this in lxdm.service:
[Install]
Alias=display-manager.service
Neither gdm3 nor lightdm have that, which suggests that it isn't
meant to be necessary.
I think what's happening is that when you install lxdm, that Alias directive
causes the debhelper snippets in its postinst[1] to break the mechanism
that is meant to arbitrate who owns display-manager.service: the part of
its postinst headed "# set default-display-manager systemd service link"
is correct, but then the #DEBHELPER# snippet runs "systemctl enable lxdm"
which sees the Alias, obeys it, and overwrites the display-manager.service
symlink with an incorrect target.
Correct, that Alias= breaks our current mechanism for arbitrating the DM to use
(that is, the sylink and the config file go out of sync).
See also Martin pitt's comment for lightdm way back when:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=733220#25
Actually, we revisited that with Martin and we can use Alias in relation
to the correct postinst scripts to achieve this in a clean way.
See the snippet I proposed on bug #764607.
Cheers,
Didier
