How to get rid of session 'memory' in xfce for a clean restart?

[Chris G-6]

I'm running xfce4 version 4.4.2.1 on xubuntu 8.10.

The latest xubuntu upgrade has, for some reason, stopped X starting up
properly.  Looking at the .xsession-errors file I think this *may* be
due to the restart (after the kernel upgrade) trying to restart some
applications that have problems.

How do I get xfce4 to do a 'clean' X startup with no session 'memory'?
I currently don't even get to the login screen so I can't do it from
there, presumably the restart is trying to give me back my session
exactly as it was (and failing).

If you do not even get the login screen, it is unlikely that Xfce is
even starting (unless you have configured gdm to auto-login). It is
rather likely that the upgrade caused your X to not start up properly,
and this is not related to Xfce.
If you really find out that the Xfce session is the problem, remove
.cache/sessions/ to reset your session.

there are *loads* of messages from digikam (which I think may be the
cause of my problems) and, at the end, from some bits of xfce.

I'll try removing .cache/sessions/ and see if it helps, I don't really
have anything to preserve in sessions.

No different, the .xsession-errors was an old one I suspect because I
removed it and it hasn't reappeared.

How do I diagnose this?  I have virtual consoles working (fortunately,
and hence this E-Mail) but that's all.  There don't appear to be any
errors in /var/Xorg.0.log but I've still got no GUI at all, no login
screen, nothing.  I just get the xubuntu startup screen with the bar
moving across and when that finishes there's just a blank screen.

As Alexander was saying, you should ask on an xubuntu mailing list, as
this is an X problem and has nothing to do with Xfce. You're much more
likely to get help there than on this mailing list.

On a side note, it seems odd that there are no errors in the logs. I'd
recommend including the log files when you ask for help on some
(x)ubuntu related list / forum / whatever.
