Upon login, session crashes and returns me to greeter

Question

I'm running Elementary Luna Beta 1 and I'm running into some pretty difficult problems. Whenever I try logging in with the greeter (either pantheon-greeter or even lightdm-gtk-greeter), it immediately returns me to the login screen after the screen goes black.

I'm not seeing anything significant in ~/.xsession-errors or in /var/log/Xorg.0.log. Where else should I look for potential problems? How can I debug what's going wrong with my session? If I log into a guest session, everything works fine, but I can't log into my own account.

Answer 1

Base on feed back from comment and with minimum info in .xsession-errors. Do following

1. Check /var/log/syslog

2. Compare groups

   groups <username>
   

3. Compare home directory permission

   ls -lh /home
   ls -lh /home/<username>
   

4. Create new home directory and move stuff back one by one

   cd /home
   mv username username.old
   mkdir username
   chown username:username username
   

   Then try login from WM again. If that works, it is most likely some thing in those hidden directory stopping you from login, move those hidden directory from /home/username.old to /home/username one by one to pin point it.

Answer 2

Evidently, I had some NVIDIA configuration in my home folder as well as .Xauthority files. I moved those into a backup folder and I was able to get in. As suggested elsewhere online, I then double-checked all of my power connections inside of my computer case, as this is often why drive issues happen.
