Today, I updated to Ubuntu 12.10. After re-starting, like the updater suggested, the toolbar on the top of the screen, and the dash won't load. I seem to be missing other features, as well, like alttab to switch windows, etc.
I am able to access the Terminal, by typing CtrlAltT, which is how I was bale to access Firefox.
How do I fix this problem?
