After running a routine update and rebooting, my computer running Ubuntu 14.04 is now completely unusable. The lightdm screen comes up and accept my password, but it immediately redirects to itself.
Googling shows this is a common bug and no one has really figured out a solution. I tried all the common fixes, including:
- checked perms of ~/.Xauthority, owned by me
checked ~/.xsession-errors of clues, all I see is
init: at-sp12-registryd main process ended, respawning init: at-sp12-registryd respawning too fast, stopped init: gnome-session (GNOME) main process terminated with status 1
checked /var/log/auth.log for clues, saw:
lightdm: PAM unable to dlopen(pam_kwallet.so): /lib/security/pam_kwallet.so: cannot open shared object file: No such file or directory
Researching this showed it's a normal error and just means I'm not using KDE, but I tried installing pam_wallet anyways. This made the error in the log go away, but I still can't login.
checked my ~/.profile, ~/.bashrc, ~/.bash_aliases for any includes and malformed lines that might be breaking my login, but found nothing
- sudo apt-get update; sudo apt-get upgrade; sudo apt-get dist-upgrade; sudo reboot
- tried logging in to Gnome-Shell and Unity, neither work
- logged in as guest, which worked
but none of these worked or helped me shed light on the problem.
What else might be causing this?
