My Ubuntu is not opening when I use my administration account. My Ubuntu is 12.04 version.
My other user account (which are not password protected) are opening. But I can not access my administrative account through the user account. I can not do anything (update, upgrade, accessing my files,..).
The main problem when ever I give my password it does not open my account like it was opening in past. When I am in my administrative account then I can not shutdown and restart my computer too. It get stocked; I have to forcefully shutdown.
So the problem is not with the password (as it is the correct password) the problem is something else which I can not figure out.
Please help me and guide how to regain my access to my administrative (main) account.
