I have a clean install of Ubuntu 14.04 in which the "Shutdown" and "Restart" button's bring up the "Shutdown/Restart" dialog but upon clicking one of these options, does nothing. By nothing I mean, there is not even feedback from the UI that I've clicked the button until I move my mouse. After clicking either button, the dialog box remains open until I move my mouse at which time the dialog box is closed.
Steps attempted so far to troubleshoot:
- Install ConsoleKit
Added the following to /etc/pam.d/common-auth:
session optional pam_loginuid.so
Running:
sudo reboot
and
sudo shutdown -hP now
work as expected
I suspect the issue is related to ConsoleKit but I am not familiar enough with it or the process used for the Shutdown/Restart buttons in Unity to debug further. I have also tried tailing /var/log/* while attempting to shutdown and this came up empty.
EDIT:
It's come to my attention that Ubuntu uses dbus to facilitate the shutdown/restart functions from the menu. As such, I've enabled dbus debugging and HERE IS THE OUTPUT OF:
sudo dbus-monitor --system
Could use some help making sense of it, though I'll continue trying to do so myself.
