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)
