Earlier today I finished an apt-get upgrade and my machine reported that it needed to be rebooted. So I shut everything down and rebooted the box. The shutdown didn't go as smoothly as I would like and I ended up having to do a hard reset.
But the machine then proceeded to come back up normally. I got the lightdm login screen with my background. When I attempted to login however strange things happened. Initially nothing worked, I saw the background but that was it.
From a different machine I was able to log in and tried rebooting again and when it came back up and I attempted to log in I got my background with nothing else.
I've been searching the Internet for the last few hours trying to figure something out but to little avail. I have tried
sudo service lightdm stop rm -f ~/.config/nux/dconf/ sudo reboot sudo apt-get install gnome-session-fallback
Logged in using the fallback gnome environment which works but most of my applications like adjusting background etc. do not. I also tried installing cinnamon but that has proved to be a no go as it crashes immediately upon logging in.
The Gnome-session-fallback has at least provided a destop environment I can work with. But now when I try to log into Unity I get a black screen with nothing but a mouse pointer. Which is semi functional (i.e. it moves) but that's all.
I'm a little lost as to what to attempt next. I'd like to go back to using unity if anyone can suggest a way to do that.
