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?

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]
