How to shutdown automatically from command line in 13.04

  • 772

I know there is already a similar question about this topic. But that question was only about how to get the shutdown dialog in general. I need to get back the countdown of the old shutdown dialog (Ubuntu <= 12.10) which shutdown the system after 60sec.

geobuntu suggested this dbus call in his answer:

dbus-send --print-reply --dest="org.gnome.Shell" /org/gnome/SessionManager/EndSessionDialog org.gnome.SessionManager.EndSessionDialog.Open uint32:2 uint32:0 uint32:60 array:objpath:/org/gnome/SessionManager/EndSessionDialog

qdbus indicate that third argument is max_wait which should (in my opinion) set and start the countdown:

~$ qdbus org.gnome.Shell /org/gnome/SessionManager/EndSessionDialog
[...]
method void org.gnome.SessionManager.EndSessionDialog.Open(uint type, uint arg_1, uint max_wait, QList<QDBusObjectPath> inhibitors)

But it doesn't. I already tried various values for type and arg_1 without luck.

EDIT: Actually the countdown is more 'nice to have'. What I really need is that the system WILL shutdown without any extra user action. It should work without sudo (including any no-password sudoers).

I would prefer dbus calls cause I already have a nice list of dbus calls which will shutdown all DE's except Unity >= 13.04

EDIT2: I had a look into Unity source. I don't know C++ but for me it looks like arg1 and timeout_length are not handled in source (can someone with C++ knowledge please confirm this?). Maybe this will be added in later releases.

EDIT3: I reported this as bug #1256703 on Launchpad.

    There was a great answer from Majal Mirasol about this. He suggested to use

    /usr/bin/dbus-send --system --print-reply \
--dest="org.freedesktop.ConsoleKit" \
/org/freedesktop/ConsoleKit/Manager \
org.freedesktop.ConsoleKit.Manager.Stop

    This will work perfectly for me.

    If you like this solution please send kudos to Majal's answer and not this one.

  2. Run sudo visudo in the terminal and add the following line:

    %user_name ALL=(ALL) NOPASSWD: /sbin/poweroff, /sbin/reboot, /sbin/shutdown

    This allows you to run the above three commands, using sudo, however with no password.

    So, sudo poweroff will now result in a password less shutdown.

    then create an alias by putting the following at the end of ~/.bashrc_aliases by opening it as -

    gedit ~/.bash_aliases

    and add the following in the last -

    alias shutdown='sudo shutdown -h now'

    Now lets load the changes to the .bash_aliases file.

    source ~/.bash_aliases

    Try shutdown . hope it will work.
