Suddenly I am unable to log in into one of my user (user1) accounts, it is blinking after booting although for other user accounts I am able to log-in properly. My /home/user1 directory is 70% full. I am able to log-in through terminal to the user account user1. How to solve this problem ? URGENT
If it logs in to another account, then turn off 'Automatic Login.' This should take you to the Login Screen every time.
To do it, go to: System Settings -> User Accounts. Click on the user that is logged in at boot and turn off the automatic login feature. Note: It may ask for a Admin password if you are on a 'Standard User' account.
Hope this helps!
