Cannot login to any TTYs - Wrong password
I am using Ubuntu 12.10 with Unity desktop. 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[3361]: 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 come I can't log in to TTY1?
Perhaps your keymap configuration is wrong fo the tty (which is a different setting than Xorg / Unity) and your password is wrong because of this. Try entering your password when you're prompted for your username and see if the characters turn out right; don't press enter, but delete your input (since login tries get logged and your password would be in that logfile). If something is wrong, you must set the keymap. In unity, open the terminal application and enter
sudo dpkg-reconfigure console-setup
and choose the right layout there. You might have to reboot.
The most common cause of this error is simply typing your password (or username) wrong. The keymap in the console is often subtly different from the one in X.
Make sure you're typing the correct password by first typing it in the login field where you can see if it's being written as expected.
Check that you're typing your username exactly as it should be (including case), by comparing it to the output of whoami run in a terminal.
Another thing that will cause this exact same error message is if your login shell is not listed in /etc/shells. Find which shell you're using by searching for your username in /etc/passwd:
grep "dave" /etc/passwd
(replacing dave with your username) you should see something like this:
dave:x:1000:1000::/home/dave:/bin/zsh
The last field (/bin/zsh) is your shell. Let's search for it in /etc/shells:
grep "/bin/zsh" /etc/shells
We should see something like this:
/bin/zsh
/usr/bin/zsh
But if you don't, that's what the problem is. Try re-installing zsh (or whatever shell is missing from /etc/shells), and if that doesn't work, add it manually:
echo `/bin/zsh` | sudo tee /etc/shells
(we use tee because > redirection doesn't work with sudo)
Maybe the layout is different.Also to login in console you have to enter username wich can be different from your name in profile installation option.For example there is user profile name wich is Andrew but the user pc name can differ.See it here 
I have my profile name on russian and when i login to console i use english login name. If the problem not in this try it http://www.noobslab.com/2012/02/reset-your-forgotten-password-quickly.html
