Reboot without sudoer privileges?

  • 772

I've been trying to get my ubuntu restart without having to edit the sudoers. This has been possible before (in lucid I think) using a dbus command:

dbus-send –system –print-reply –dest=org.freedesktop.ConsoleKit /org/freedesktop/ConsoleKit/Manager org.freedesktop.ConsoleKit.Manager.Restart

But this gives me an error. Looks like things have changed.

In KDE (which I don't use) one has something similar (see this answer)

Could anyone show me an alternative way to make my machine reboot from a script (without adjusting rights)

10.10 command-line reboot dbus

    From Launchpad Question #85949:

    Logout 

    dbus-send --session --type=method_call --print-reply --dest=org.gnome.SessionManager /org/gnome/SessionManager org.gnome.SessionManager.Logout uint32:1

    Reboot 

    dbus-send --session --type=method_call --print-reply --dest=org.gnome.SessionManager /org/gnome/SessionManager org.gnome.SessionManager.RequestReboot

    Shutdown 

    dbus-send --session --type=method_call --print-reply --dest=org.gnome.SessionManager /org/gnome/SessionManager org.gnome.SessionManager.RequestShutdown

    If some application is inhibiting logout/reboot/shutdown, no action will be performed and gnome-session will show a confirmation dialog.

    So add the command:

    dbus-send --session --type=method_call --print-reply --dest=org.gnome.SessionManager /org/gnome/SessionManager org.gnome.SessionManager.Logout uint32:1

    to your script.

    UPDATE: The DBus interface for suspend and hibernate has been removed, to suspend and hibernate from the command line, use pmi.

    sudo apt-get install powermanagement-interface

    • Suspend:

      pmi action suspend

    • Hibernate:

      pmi action hibernate
    • 13

  2. apt-get of pmi in 10.10, installs powermanagement-interface, when pmi action suspend or pmi action hibernate called, returns ServiceUnknown error
