     "the gnome- or kde-session-manager, to HAL or to DeviceKit and if none of "
     "these works, the command 'sudo shutdown' will be used (note that when sending the "
     "request to HAL or DeviceKit, or the shutdown command is used, the Session will never "
     "be saved. If the shutdown command is used, the program will only be able to shutdown and "
     "reboot). So if nothing happens when the shutdown- or reboot-time is reached, it means "
     "that one lacks the rights for the shutdown command. In this case one can do the following:\n\n"
     "Paste the following in a terminal:\n"
