Forced to use command lines to logout/shutdown: sudo shutdown -h 0 sudo restart lightdm -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/891083 Title: ubuntu wont log out/shut down To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/indicator-session/+bug/891083/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
