--- Comment #8 from Jani Nikula <jani.nikula at intel.com> ---
What's the output of this when you first boot, and the screen is presumably
black:

cat
/sys/class/backlight/intel_backlight/{brightness,actual_brightness,bl_power}

I understand you may have to ssh into the machine or script this at late boot.
