when you say "default session", do you mean in the top-right menu? If
so, the LightDM (not the greeter) should run /etc/X11/Xsession, which in
turn might run different stuff depending on your local configuration
(check in ~/.xsession and ~/.Xsession).
Could you provide logs from /var/log/lightdm and ~/.xsession-errors ?
In any case, it's likely not a but in the greeter (whose role is
minimal), but let's wait for more info before reassigning.

Hi, that screenshot is not lightdm-gtk-greeter

And the log confirm you're using arctica-greeter, so it's definitely
unrelated to lightdm-gtk-greeter. But in any case, as I said before, you
can select the session in the greeter but in the end it's handled by
Lightdm itself.
Looking at the log you provided, we can see:
[+264.18s] DEBUG: Session pid=5587: Running command /etc/X11/Xsession
default
[+264.18s] DEBUG: Creating shared data directory
/var/lib/lightdm/data/scheini72
[+264.18s] DEBUG: Session pid=5587: Logging to .xsession-errors
So you're definitely using /etc/X11/Xsession with the 'default'
parameter. You should be able to select a specific session if the
desktop environment you use has it (for example Xfce).
In any case, could you provide your .xsession-errors as well as your
.xsession or .Xsession just in case?
It looks to me like an configuration issue rather than a bug though.

Ok
> So, I’m using the default. I’m not in front of my computer right now, so I would send it later from /etc/X11.
Please especially send the .xsession-errors log (check for personal
information first though). /etc/X11/Xsession sources various files from
/etc/X11/Xsession.d and the session selection (if not selected in the
greeter) should be done from
/etc/X11/Xsession.d/50x11-common_determine-startup

> As mentioned, the difference between using the login between Debian 11 and 12 is, before the selection of respective xsession (xfce, kde, gnome) did stay after restart. Now it’s not the case anymore.
Sorry but it's not at all clear what you mean here: are you using the
*default* session, or are you choosing a session in the greeter and it's
not actually selected? In the lightdm log you sent, you were using the
default session.

I don't think so, again it doesn't look like a but in the greeter.

Yes indeed, this is very confusing. Sorry I misunderstood from the start. And
in the end, yes it looks like a bug in the greeter, so I'm reassigning there.
Sorry for the lengthy process.

we have worked on this on the arctica-greeter upstream side, although
we don't (yet) honour x-session-manager symlinking. This would still
be a needed patch in arctica-greeter upstream.
I will upload arctica-greeter's latest version to unstable (and thus
testing) soon, so we can proceed from there improving this issue.
Thanks,
Mike
