"Shutdown" or "Restart" logs out

  • 772

While logged in as a sudo user, click the right top power icon, then select and click Shutdown menu, it comes up with a dialog asking if I want to close all programs. The dialog has two options: restart or shutdown. Choose either one logs me out. Syslog has the following line about restart:

WARNING: Unable to restart system: Authorization is required

This happened after I installed NTP and some OpenStack packages while working in a prototype project. My Ubuntu's software is up to date as of this writing.

Anyone encountered the same problem in 12.04?

shutdown logout 12.04 restart

  1. Sadly this is a known bug in (probably) consolekit LP #838792

    The workaround for the time is

    sudo reboot

sudo shutdown now -P

  3. Following these websites information: http://www.freedesktop.org/software/polkit/docs/0.105/pklocalauthority.8.html and https://bugs.launchpad.net/ubuntu/+source/policykit/+bug/1033305

    Seems to have resolved our problems with the lightdm shutdown button not working for all users on Ubuntu 12.04.3 LTS (GNU/Linux 3.11.6-031106-generic x86_64)

    vim /var/lib/polkit-1/localauthority/20-org.d/usershutdown.pkla

    Then add the following lines to the file.

    [Allow Shutdown]<br>
Identity=unix-user:\*;unix-group:*<br>
Action=org.freedesktop.consolekit.system.stop-multiple-users<br>
ResultAny=yes<br>
ResultInactive=yes<br>
ResultActive=yes<br>

[Allow Restart]<br>
Identity=unix-user:\*;unix-group:*<br>
Action=org.freedesktop.consolekit.system.restart-multiple-users<br>
ResultAny=yes<br>
ResultInactive=yes<br>
ResultActive=yes<br>

    Then enter service lightdm restart and/or a reboot of the machine is needed. Tried before logging into the machine and then again after someone logged in.

  4. My workaround for this annoying little bug is this, I create a launcher with the following:

    To Shutdown:
    sudo shutdown -h

    To Restart:
    sudo shutdown -r

    You will then be asked your super user password. I put this launcher on the desktop and use that until the bug is sorted out.

  5. Maybe the problem is caused by the HSQLDB Server. I just filled a bug about it:

    https://bugs.launchpad.net/ubuntu/+source/hsqldb/+bug/1153856

    Workaround:

    sudo apt-get remove hsqldb-server

  6. I had the same troubles - the guilty one was kalarm. After I disabled it, shutdown started to work properly again.

  7. A GUI resolution is to install Cairo-dock from the repository and click on the Shutdown button on that menu to shutdown or restart.

    While using the terminal commands work. For some people, having to go to a terminal screen is at least, overly complicated, and also a lot of work.

    I've been using this Gui workaround for the past 6 Ubuntu version releases.

    This can be installed from the software center or cli:

    $ sudo apt-get install cairo-dock
