I logged into the Ubuntu 12.04 LTS and instead of installing it... I pressed the Log Out button, thinking of installing it some other time.
But then a screen appeared asking for Username and Password.
I typed in my name as the User name and a password of my choice..I was halfway through typing my password..just then I remembered that I had to Login as 'root' so I hurriedly pressed the Back button... but instead the user name and half password I typed.. got submitted.
Now it is asking for User name and Password and when I type the ones which I had initially typed..its showing Login Error :(
But the problem doesn't end here... m unable to shut down my laptop.. its been more than 12 hours and m stuck at this login screen... plzzz help me out!
