You just need to turn the Unity plugin back on. The problem is this is a pain in the bottom because you've now got no graphical method to do this. So:
Try to open a terminal with Ctrl+Alt+T.
This may not work but you can try right clicking on the desktop and selecting "Open terminal here." Otherwise, you may need to change to a "hard" terminal by pressing Ctrl+Alt+F1 and log in.
Install compizconfig-settings-manager by running
sudo apt-get install compizconfig-settings-managerThen run it with this:
DISPLAY=:0 ccsm &The first part tells the terminal which display you want it to load on (otherwise it won't have a clue).
If you switched to a TTY in step 1, switch back to the graphical server by pressing Ctrl+Alt+F7 (or Ctrl+Alt+F8 sometimes).
There there should be a CompizConfig Settings Manager waiting for you.
Find the Unity plugin. Enable it. You will be asked "Ubuntu Unity Plugin requires the plugin OpenGL. Enable Ubuntu Unity Plugin / Enable OpenGL"
Everything should spring into life but if it doesn't, you might have to restart. You can do that by going back to the terminal and running sudo reboot.
5If the screen grays out a bit and the mouse changed into an X, then there is probably/likely an X authentication problem. I had this happen to me because (after playing around a bit) I ended up with an empty (size 0) /home/carlo/.Xauthority file owned by root. Removing that file fixed the problem (if you kill Xorg it will restart and then let you login as normal).
