I keep hearing about these things known as tty's.

  • what are they

  • how can I access them

  • what do they do?

tty is one of those funky Unix commands that prints (or, displays) to standard output the name of the terminal connected to standard input.

These are commonly used as a way to get access to the computer to fix things, without actually logging into a possibly b0rked desktop.

By default Ubuntu has 7 tty's.

1-6 are command line only, 7 runs your X session (your normal desktop).

To access them, use this keyboard shortcut:

Ctrl + Alt + F1

(changing F1 to F1-F6 to access the terminal that you need)

To get back to your X session (the normal desktop),

Ctrl + Alt + F7

I dont know if it is the right place but your question and answer pointed it for me. –  Sushantp606 Nov 30 '13 at 12:40
