Answer 1

As you can log in on a virtual terminal (reachable with Ctrl+Alt+F1) you can

1. re-install the Ubuntu desktop including all its necessary dependencies:

   sudo apt-get install --reinstall ubuntu-desktop
   

2. You should now the be able to restart the display manager

   sudo initctl restart lightdm
   

   and switch back to the graphical session with Ctrl+Alt+F7. Alternatively you can reboot Ubuntu.
