** Description changed:

- 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.
+ [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.
