It's my first question and I am pretty much desperate by now. So please look upon any errors likely to occur in my question.
So, I had Ubuntu 12.10 running alongside Windows 7 (which is the default OS). A few months back I tried do-release-upgrade and before it finished, I aborted it.
2 days ago I ran
sudo apt-get update && sudo apt-get upgrade since Software Updater kept saying
"not all updates can be installed".
So when upgrading finished, I rebooted my computer and got a total blank screen after logging in. I tried everything I could find on the net (uninstalling and then installing lightdm again seemed somewhat to work, at least the screen wasn't black anymore). But what came wasn't much of an improvement. The dash was gone, along with the top bar. It was a total wallpaper, the whole screen. Hitting
ctrl+alt+F1 brought the terminal and that was the only thing that worked correctly. With that I installed CompizConfig Settings Manager and after a lot of fooling around managed to get the dash back, but no top panel. But it was nothing near right. All open applications show a question mark instead of the app logo in the dash. The menu is always on top of every window, instead of when I hover my mouse there. What is worst about the whole thing, is that the log in screen still shows Ubuntu 12.10, even though the terminal says it's 13.10 and running
do-release-upgrade brought the message that no upgrade is available.
Brothers and sisters, what can be done?
