I have only one user account on Lubuntu 13.10 and the automatic access was enabled. I decided to change this option; I wanted to see the login screen on startup where I can choose the user and run the session only typing my password.
I went to Menu > Preferences > Default applications for LXSession > Settings and ticked the Upstart Session option. After reboot I can see the login screen, I can choose between my account and the guest one, I select my account, I type the password, it takes it, it seems for one second to load the session, the panel... but it takes me immediately back to the login screen!
I can't get in my account any more! I guess I have to modify (with a live session) some files in the
/usr/share/upstart/session folder, but I don't know how. Or maybe I can log in to my account in another way, then change the Upstart Session option!
What should I do?
