I would like to know if /sys/class/backlight/<hardware>/actual_brightness is then saying something different than /sys/class/backlight/<your hardware>/brightness.

  Makes sense. I'll get it patched and repost in a couple of hours.
  
  FYI: this where a remote control app like NoMachine comes in handy - you can issue commands on your tablet (or phone!) and watch what happens on the big screen.
