Gnome power off button on panel menu doesn' t work

Recently, the power off button in the panel menu has no effect for me? Any clue on solving this issue? I have latest Gnome 3.16.

Were you able to solve this? It is happening to me as well for both power off and reset, but not lock.

I switched to KDE.

Ok I was able to solve it. Journalctl was showing this when I tried to press the shutdown button:

So for some reason gnome didn't have permission to shut down. systemd however is supposed to allow regular users to shut down, so I gave "systemctl reboot" a try as well, and it was broken.

The fix:
systemd needs polkit, so I installed that and removed my conflicting copy of polkit-consolekit that somehow wound up on my computer, even though it is for non-systemd systems. Someone must have bundled it as a dependency I guess? Oh well, hopefully this helps someone in the future.
