I was using these commands in terminal:
sudo apt-get install gksu gksu nautilus
I needed to move some files from one account into another & then I wanted to rename some of the accounts. I got a failure message & my desktop wallpaper went black.
I logged out & now I cannot log into ANY account at all. One account is my son's (with his school homework on it) & the other is mine (an admin). There is no password on my son's but I have one on mine.
I cannot get into either account...I am brought back to the login screen. I can't even get to a terminal to make any changes. Any help would be appreciated!
