Unity top bar, side bar, and window decorations missing after upgrade to 12.10
I just upgraded Ubuntu last night to 12.10 from 12.04. When I rebooted like it asked, everything seemed fine, except one of my monitors had a white screen, and I could not use it. After some tweaking in the AMD Catalyst center, I got it to work, but now Unity wont load, and the bar up top wont load either. I am in suspicion that it a problem with Compiz, but might be completely wrong. Any tips on getting this to work?
I am also kind of new at Linux, but I could open a terminal and get Opera open for web browsing, but it is really choppy and slow.
