Ubuntu: Lost user login on upgrade to Ubuntu 13.10


I just upgraded to 13.10 this weekend (I know 14.04 is out, I'm not doing that yet) and have lost my login. There used to be two user accounts I could choose to log in from on the startup page, mine and the dummy one created by a coworker when he was helping me with something. After the upgrade, the only user account I could log in to belongs to my coworker. My account data is still there (I can access it when I log in as him and cd to /home/username) but I don't know how to log in as my old user account. It also doesn't show up in the user accounts Settings view. How do I add it back?

Note: I tried using the answer to this question: Why are my user accounts missing from login screen after upgrade to 14.04 from 12.04 ? and got the response "user 'username' already exists"


I had to edit /etc/lightdm/lightdm.conf as root and add:

greeter-hide-users=false  greeter-show-manual-login=true  allow-guest=false  

When I go to the startup screen, I am now able to type in my username and log in.


You could try to install lightdm again enter from the terminal:

   sudo apt-get install --reinstall lightdm  

it should work fine that way.


I have had the same problem you could also try to enter in the terminal:

    sudo apt-get autoremove gdm      sudo apt-get autoremove lightdm  

and then in the terminal enter:

    sudo apt-get update      sudo apt-get install lightdm      sudo apt-get install gdm  

and then in the terminal enter:

    sudo -f --dismiss-Option::="unity-greeter-gtk" install --reinstall unity-greeter  

and then reconfigure the unity-greeter enter in the terminal:

    sudo apt-get --reconfigure unity-greeter  

and this could maybe also work fine this way.
