I was trying to upgrade my 12.04 LTS to 14.04 LTS. While upgrading, the system suddenly showed a screen saying you system is running in low graphic mode. Now to solve this I wanted to go through the steps listed here.
Now to follow these steps I need to do CTRL+ALT+F1 and login. The problem is I can't seem to login. It says login incorrect everytime. I have tried resetting the password but no luck. And I also checked if it is a keyboard layout issue and if /home is encrypted. It is neither.
