Checked the login screen shutdown problem using KDM: this works. Reviewing the PAM files shows that the kdm file calls the common-session file.
Tried version of #32 * modified to session required pam_systemd.so in /etc/pam.d/common-session * reboot => did not work Tried version of #32 * modified (reverted) to session optional pam_systemd.so added session optional pam_loginuid.so in /etc/pam.d/common-session * reboot => did not work Tried version of #32 * modified to session required pam_systemd.so session required pam_loginuid.so in /etc/pam.d/common-session * reboot => did not work So nothing works so far. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1240336 Title: Not authorized to perform operation / Unable to determine the session we are in: No session for pid To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm/+bug/1240336/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
