Bug description:
  [Impact]
  Using brightness hotkeys currently changes brightness correctly, but such changes fail to be visible in the gnome-control-center UI; which leads to confusion and unpredictable behavior if the brightness is then adjusted using UI in the same session.

  [Test Case]
  1) Open gnome-control-center (power indicator -> System Settings...)
  2) Switch to "Brightness and Lock"
  3) Use the brightness hotkeys to adjust screen brightness
  4) Observe slider behavior.

  Without the patch the slider should not move.
  With the patch, slider should follow brightness adjustments done via hot keys.

  [Regression Potential]
  Minimal risk. The slider does not currently follow key brightness adjustments. Possible regression scenarios could include the slider no longer responding or changing brightness when interacting with it; or more confusion in mixing up hot key and slider brightness adjustments.

  ----
  For systems equipped with hot keys to adjust screen brightness, the brightness gauge in "gnome-control-center screen" is not responding to brightness hot-key actions.
