Bug description:
  [IMPACT]
  * Regardless of settings in the "Brightness and Lock" Panel, screen will power off after 10mins.

  As part of the new lock-screen in gnome-shell 3.6 (when running on
  gdm), a watchdog timer, that disables the builtin X screensaver was
  moved into gnome-settings-daemon 3.6. Previously this was in gnome-
  screensaver however that is no longer used with gnome-shell/gdm
  combination.

  Since Quantal is still using gnome-settings-daemon 3.4, currently we
  are missing the watchdog timer for gnome-shell session on gdm.

  This is an upstream git patch take from gnome-settings-daemon 3.6.

  [Test case]
  1. Run gnome-shell from gdm.
  2. Set "Turn screen Off" in Brightness/lock panel to Never
  3. Wait 10mins and the screen will turn off.

  [Workaround]
  Install gnome-settings-daemon 3.6 from gnome3-team ppa.

  [Regression Potential]
  The code in this patch was copied from gnome-screensaver into gnome-settings-daemon, so should not cause any problems. However when running a session that uses gnome-screensaver (Unity, gnome-shell on Lightdm), this watchdog timer will be duplicated. This is probably harmless but it might be best to patch it out gnome-screensaver.

  === Original Bug report ===

  Just updated to the latest quantal today and then tried to watch a
  movie in Totem. Screen powered off every 10 minutes, reliably. Tried
  setting the power save to 'never', or to '1 hour', tried it with auto
  screen lock on or off, screen always powers off after 10 minutes
  exactly.
