Hi there!
My Unity stopped functioning properly.
At first, it was working fine. I did some tweaking, had fun with cubes, etc, and all was good. Days later I tried setting up automatic mounting for USB sticks and such. The only thing I changed was my /etc/fstab. I can post what I did exactly, but in my logic what I did and what happened are not connected:
When I rebooted to see if no errors appeared while loading fstab, my panel and launcher never showed up again. Windows don't have titlebars, ctrl+alt+T only works sometimes, ctrl+alt+F1-F6 was already problematic before (monitor in standby status), in short: a hard time. I dropped to ubuntu 2d and tried to fix, using a tuxgarage thread (http://www.tuxgarage.com/2011/04/missing-top-and-side-panels-in-unity.html). I tried all steps, none of them solved my problem, then I removed and reinstalled a) Nvidia drivers i had installed, and b) unity, compiz, ubuntu-desktop, the whole lot. This messed up my display settings in all desktop environments, which I got working again with some difficulty, but still unity was not working.
According to unity-support everything should be fine, but obviously something is wrong.

So 3 questions:
1 Does fstab have anything to do with all this? (I never set it back since i don't believe it connects)
2 Has someone else had this problem before?
3 What do I do now?
