I was trying to disable the 'global menu' feature in Unity, and Unity began to malfunction. I was unable to move windows, the left menu bar had disappeared, and the top panel was also gone. I couldn't open a terminal as I couldn't move windows to get to my shortcut.
I used a virtual terminal(tty2), logged in, used sudo, and executed
# unity --reset
but it never finished.
I have pasted the output here
