12.10

I've just installed 12.10 from scratch. Unity also started okay, but in a poor resolution. I found a setting (I think it was in "software sources") to change the display driver to Nvidia, and then I rebooted.

When Ubuntu now starts, it goes to the desktop (I see a file that I saved to the desktop) but there are no other screen elements -- no Unity, no menu bar at the top, no window decoration, nothing.

Ctrl-Alt-T and Ctrl-Alt-F2 work as they should, but it's kinda limiting...

How can I restore the default driver? I guess I need a way to open those "software sources" settings again - or anything else that could fix it! I hope I don't have to type all this by hand.
How can I install a proper Nvidia driver so that I can get up to 1280x1024? My old tricks don't seem to work, but perhaps they might if I solve #1...
