- * To test screen shield, make sure to kill gnome-screensaver.
- *
  * If you are setting org.gnome.desktop.session.idle-delay directly in dconf,
  * rather than through System Settings, you also need to set
  * org.gnome.settings-daemon.plugins.power.sleep-display-ac and
  * org.gnome.settings-daemon.plugins.power.sleep-display-battery to the same value.
  * This will ensure that the screen blanks at the right time when it fades out.
