I am new to Ubuntu (12.10 with Unity desktop) and Linux for that part too, so I might not be asking the right question. But here goes.
I go to TTY1 by pressing keys CTRL + ALT + F1, where I am asked to enter username and password, which I do, but I get the message "Login incorrect". In my log file
/var/log/auth.log this entry has been made:
Oct 23 13:17:45 SomeName login: FAILED LOGIN (1) on 'dev/tty1' FOR 'aUser', Authentication failure
I do not have the wrong username or password. It is the same username/password I use to log in when Unity starts.
So how came I can't log in to TTY1?
