I decided to give Ubuntu a try after all these years using only Windows as OS.
I downloaded that windows installer from their site and installed Ubuntu. Everything went well until I decided to update the drivers and apps. It seems to be a bad idea, because I can't see the sidebar anymore (the one with the "quick launch options") and some graphic elements from the OS are not present, like the top bar with the clock.
Another issue: I always see an error regarding Compiz after a couple of minutes, saying that it stopped responding.
Am I missing something?
I'm using the 12.10 64bit version.
I googled about the problem and it seems that Compiz is bugged like hell in 12.10. I'm uninstalling it and giving 12.04 a try. That's too bad, because I like many features from this version, specially the use and feel. But I can't stand using it without the left bar and a graphic interface at all.
