Public bug reported:
Adjusting the slider all the way down to minimum turns the backlight
off.
The range of the slider currently is from (backlight turned-off) to
(maximum back-light brightness). Expected behavior is to have slider
range from (minimum acceptable brightness) to (maximum brightness).
This behavior was not present in 12.04precise. In precise, at minimum
brightness setting, the backlight remains on.
#Brightness value obtained at minimum position of brightness slider
