The issue i'm having with kali, is that i can no longer login as a user. I can only login as root. I can login to my users through the console, but cannot from the GUI login screen when booting the machine. To me this screams permissions, but i checked every where i could think of, and didn't see anything wrong. Does anyone have experience with this issue that could help me?

recent changes made was that I configured a windows xp virtual machine w/ mysql server and i installed Nessus. The pc worked fine until i rebooted.
