I upgraded from 12.04.1 to 12.10 via the Update Manager and the upgrade said it completed successfully, however after rebooting the Unity task bar was missing along with the launch bar and the window decorations.

All compiz settings seemed to be purge deleted, and at first boot it gave me a system error. The desktop exists, and once I remember I messed up the compiz settings and just had to press Ctrl+Alt+F1 and in the virtual terminal type unity --reset then sudo reboot.

Everything worked as if I reinstalled the entire operating system. This time it said:

Warning no variable set. setting to :0. The reset option is now dupricated.

What am I suppose to do now? I need this fixed as soon as possible because I need a couple of certainly installed programs and the data within them (long story short).

I finally got Unity back at a normal resolution with compiz working as usual (apparently). It doesn't feel as snappier as before, but at least I can work with it.

This is what I did (hope it helps others):

Tried resetting xorg.conf file as @RobertPitt suggested (which, actually, did nothing for me).

Then tried what @Freedom suggested, but there was no entry inside the additional drivers tab.

Googled for a while and tried the steps outlined in this page and this page. After following the first web page steps nothing changed. As for the second page, I couldn’t get the ATI driver package to build.

Out of frustration, I got rid of fglrx with sudo apt-get autoremove fglrx --purge and rebooted sudo shutdown -r now.

After reboot, everything looked and seemed to work as usual. So weird.

By the way, I have a Radeon HD 3400 (RV620) card and there's still no entry for proprietary drivers in the additional drivers tab.
