For the maximum level causes blank screen...

Please kindly help to identify which driver handle the brightness
change, run the following 2 commands:

# echo 5 > /sys/class/backlight/acer-wmi/brightness 
# echo 5 > /sys/class/backlight/intel_backlight/brightness 

Which one works to change brightness on your machine?
	Both  of them do not work for me.Only hot keys are working. 

Writing to /sys/class/backlight/acer-wmi/brightness 

and /sys/class/backlight/intel_backlight/brightness do not cause any 

change in brightness.
