Thank you Alemann. It seems that you are right. I now skip the LightDM
log-in screen when booting and Unity starts up a lot nicer. I only have
a problem now one out of maybe ten times, where it usually crashes about
nine out of ten times.

It seems that you had exactly the same issues as I had. I went through
some of the settings on http://www.tuxgarage.com/2011/04/missing-top-
and-side-panels-in-unity.html . It might be related to unity bug
#1072329 .
