Unity doesn't load, no Launcher, no Dash appears
I've updated to 12.04 from 11.10. After going through the whole update I've lost the title bar at the top of the screen and the unity launcher. They just aren't anywhere to be seen.
Pressing the Windows key doesn't bring up anything either.
I'm not what you'd call a 'power user' so if you have an idea, please assume I have no technical knowledge.
Is there a way to roll back to 11.10? Or maybe a simple fix for my predicament.
