After upgrading from 13.04 to 13.10 unity won't seem to work for regular users. If i were to start unity as root it works though.
At the current stage, the top of the screen - that use to show the selected applications name, the date, message notifications and such - is "hollow". It's outlined by a black line and the ubuntu background is instead showing.
However, if I click it, it responds as if the statusbar was there. I can minimize and close windows etc. The same thing goes for the dashboard. !http://image.bayimg.com/b1c9a028b20ebdc91a6ed293d05233794298d37e.jpg http://bayimg.com/bABllAAfb
I've tried reinstalling unity, ubuntu-desktop, gnome-session and compiz. Ccsm shows ubuntu unity plugin as running.
It seems to me that this is probably some kind of permission problem.
