Comment 30 for bug 1441253

Hello.

I'm having the same problems with shutdown. Yesterday, I've choosed "menu/logout/halt" option instead of "menu/logout/shutdown". And problems started to happen: I could not even reboot or shutdown computer, because every time when I wanted to do this, there was a window to unblock session (I have had to enter my user password and there was not even internet connection - it could not be connected via NetworkManager! etc.) For now, a solution is: press "RESET" and next "POWER" button for a few seconds. That's the only way to shutdown computer now. I've decided to try shutdown system via shutdown(8) command but it did not work:

[~]$ shutdown now
Failed to power off system via logind: There's already a shutdown or sleep operation in progress

[~]$ systemctl list-jobs
No jobs running.

Anyway, there is not LightDM now! I have to login via "unblock" window mentioned above. And when I want to edit e.g. 'rtkit-daemon.service' file via 'mousepad', there is a WARNING message (** (mousepad:2869): WARNING **: Couldn't connect to accessibility bus: Failed to connect to socket /tmp/dbus-*: Connection refused). It happens with every file, that I want to edit etc. Log files contains many entries related to the 'rtkit-daemon' (please see 1.) But this is not important here.

I apologize for such a comment, but shutdown issues, started to happen after described situation. I have no idea if it's important, but it started to happen when I choosed - by accident - 'halt' option instead of 'shutdown' during logout.

● Release: 16.04.4 LTS
● Xfce: 4.12 (according to 'xfce4-about' command)

Thanks, best regads.
