See
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=893819
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=895418

I guess this is about the same underlying issue.

Done. But this doesn't solve the problem.

I get in /var/log/syslog:

The lightdm.log diff:

In seat0-greeter.log for systemd 237, I have:

So, it seems that with systemd 238, the login1 session is not
activated (and as a consequence, it tries to open a CK session,
which does not work, but this is not the issue here).

Do you use hidepid for /proc?

Please uninstall/purge consolekit. It's not only useless when logind is
used, but actively harmful:

I'd say that it is specific to sysvinit. I have two other machines
with similar configuration but with systemd as the init system instead
of sysvinit, and I haven't seen any such problem on them.

The only other major difference between my machines is that the one
with sysvinit uses the nouveau driver instead of the nvidia one for
the two other machines, but I doubt very much that this has an
influence.

I've also checked the logs at startup. With systemd 238 (for which the
problem occurs):

I assume that the ConsoleKit one can see with systemd 238 is a
fallback due to some issue with login1.

I could try again with systemd 238 and look at the lightdm debug
logs (I no longer have them right now since I rebooted twice) to
see if there's any error.

Not reproducible with a default GNOME / systemd as init installation.

Please investigate, if this issue is specific to sysvinit, xfce or some
other custom modification (like special kernel parameters)

This is actually an issue due to the upgrade of systemd from 237-4
to 238-4, from a previous upgrade (I thought that 238-4 was OK, but
I now remember that I didn't test after the previous upgrade due to
a freeze of the X server in lightdm).

Downgrading to 237-4 makes these menu entries work again (and
policykit-1 0.105-20 is OK with this).
