I got impatient and installed xserver-xorg-video-ati. That has fixed
things so the X server starts. I've no idea why the upgrade broke that.

Another thing the upgrade has broken is the desktop. I was using lxdm
and lxde. I now see a different login screen (presumably lightdm?) that
doesn't appear to have any method to select desktop session type and
that logs me into something that says "Ubuntu Desktop". I don't know
what that is (though I have my suspicions) but it definitely isn't lxde :(

So, grr grr grr, why has the upgrade broken my desktop! And I suppose
I'll have to start googling for ways to fix that now unless some kind
soul can point me in the right direction?

Cheers, Dave
