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 alt>tab to switch windows, etc.
I am able to access the Terminal, by typing Ctrl>Alt>T, which is how I was bale to access Firefox.
How do I fix this problem?
Edit: 10/20/12
I resorted to completely re-installing Ubuntu. If someone finds a way to fix this problem without completely re-installing, please feel free to post it below.

I am probably not the only one who has noticed this, but I just found out that Ubuntu works fine if booted into Gnome. The probalem seems to be with Unity, and people have been saying it's also a problem with ATI graphics cards.
I have tried many of the suggestions in the other threads that have been suggested, and nothing seems to work. Other idea's would be appreciated!

As Chris Carter suggested, I'm including the results of the teminal command lspci
here is my graphics card info:
01:05.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RS780M/RS780MN [Mobility Radeon HD 3200 Graphics]

To be honest I am still trying to get my head around this myself.
I had the same problem after doing an upgrade myself and it appears that Ati have yet to add support for the latest x-server.
I myself ended up doing a clean install and although I now have a usable desktop it is not taking full advantage of the capabilities of my card. I have not attempted to install fglrx as I am sure it will break my system.
There are others asking questions like this e:g Radeon HD 2000, 3000, 4000 on Ubuntu 12.04.2 and higher: fglrx (legacy) unsupported, what to do?
There is probably a way to uninstall fglrx properly to get to a usable system that someone more learned than I can explain.
