I'm using 12.04, I accidentally used Ctl-Alt-F9 and got a black full screen with command line cursor (Terminal). How can I go back to the normal Unity screen?

Another way, just press Alt + right or left arrow couple times, until you get out of gui. Ubuntu by default has like 6 black screens (ttys), and 7th is the gui –  Serg Feb 4 at 9:28

Press Ctl + Alt + F7, that is the default graphical tty.

Linux systems use to have 12 terminals: 6 for text (Ctl + Alt + F1 to F6) and 6 for graphical (Ctl + Alt + F7 to F12)

To provide a little more information, Ctl+Alt+F1-F6 are your tty terminals. I'm not sure the purpose of F9. desgua has the right answer, though. +1 –  JasCav May 2 '12 at 0:23
F9 is for graphical. –  desgua May 2 '12 at 0:26
Thanks for the info. –  JasCav May 2 '12 at 0:38
Note that Ctrl is only needed if you're in the GUI; once you hit a text console, you can switch between them with just Alt+F1-F7. –  roadmr May 8 '12 at 22:42
On LinuxMint it is CTRL+ALT+F8 –  mv288 Nov 26 '12 at 8:20
