So I recently did the whole update thing and now I'm stuck with the screen freezing after login. I've seen several threads on this but it seems my case is a little more rare. Originally I could enter my login and then the screen would freeze. After applying several fix attempts I was able to apt-get updates, remove drivers for vid card, reinstall the desktop and unity and now when I reboot it skips the login screen and goes straight to a somewhat frozen background. I have a cursor and occasionally I get the ubuntu one popup screen. Although I've tried leaving it on for over an hour with no success. If I try to login to ubuntu one I can't type anything but can open terminal and type. Please help.
