I'm uing ubuntu 12.04 desktop. I have 3 users: user1(administrator), user2(standard) and guest. I wanted to disable user1 and enable user2 which auto logs on with no password but after I did that I can't login to user1 and user2 accounts except the guest session user. I'm striped off every administrative privileges. I don't know which options are available to me and how do I enable root or user which is an administrator?
