I performed a clean install of Ubuntu 15.04 on a Dell XPS 13, but Unity fails to load. After login I see only the desktop background and the mouse pointer but nothing else. Also, right and left clicking does not work and I cannot load a terminal.
I can start Unity by hitting Ctrl+Alt+F1, logging in and running
startx, then right click and
Open Terminal and then
Unity, but that's not a solution. Also even if I do that I don't get the Menu Bar.
I tried pretty much everything I could find on Google to solve this, incl. making sure Unity plugin is enabled on CompizConfig, reinstalling Ubuntu desktop and Unity or running
dconf reset -f /org/compiz/ and then
setsid unity, but nothing helped.
On Ubuntu 14.04 everything worked fine. Any other ideas?
