No, I don't.

Done. But this doesn't solve the problem.

I get in /var/log/syslog:

[...]

The lightdm.log diff:

ypig:~> logdiff -u lightdm.log-237 lightdm.log-238
[... identical lines except pid's ...]
 DEBUG: Activating VT 7

-DEBUG: Seat seat0 changes active session to c1
-DEBUG: Session c1 is already active

[... identical lines except pid's ...]

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

** Message: 15:24:55.160: Starting lightdm-gtk-greeter 2.0.4 (Feb 21 2018, 10:34:28)

In seat0-greeter.log for systemd 238, I have:

** (process:3321): WARNING **: 15:06:56.930: Failed to open CK session: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.ConsoleKit was not provided by any .service files

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).
