Public bug reported: It happens after upgrading from ubuntu 12.10 to 13.04. The laptop became usable. I had to ssh in, and kill the lightdm. After that, I edited the config file to auto login my user. It worked fine when I started lightdm from command line.
Ubuntu version: 13.04 lightdm version: 1.6.0-0ubuntu2.1 expected: letting me login what happened: the login screen froze and started restarting in a loop making my computer unusable.
