The problem might be with the rabbitmq service user and lightdm. Lightdm can't log out because there is another "user" still logged in.
If you change from lightdm to use gdm does it help? - sudo dpkg-reconfigure gdm (select gdm) - (reboot) This bug might be related https://bugs.launchpad.net/ubuntu/+source/gnome-session/+bug/855556 although rabbitmq is a "system user" and they are talking about "real users". Very similar kind of bug has been discussed before. There was also a fix for it: https://bugs.launchpad.net/ubuntu/+source/gdm/+bug/696038 -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to rabbitmq-server in Ubuntu. https://bugs.launchpad.net/bugs/670289 Title: Laptop won't shut down with rabbitmq running To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/rabbitmq-server/+bug/670289/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
