mand:

$1= 0~96000 (0=dark, 96000= max. brightness)
#Set brightness to min
echo
0>/sys/devices/pci0000:00/0000:00:02.0/drm/
card0/card0-eDP-1/intel_backlight/brightnes
s
#Set brightness to max
echo
96000>/sys/devices/pci0000:00/0000:00:02.0/drm

Users can build into their own application to enable auto dimming
by reading the ambient light sensor and setting the LCD backlight
brightness accordingly. Or contact your ADLINK representative for
assistance.
