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.
