Thank you very much for your input. Can you try to run a bit of the
'test' I include? I'm starting to suspect different accelerometers might
give different outputs and so the heuristics might not make sense
anymore, I hope that's not the case.
You can return the brightenss with
echo 63 > /sys/class/backlight/pcf50633-bl/brightness
... in the meanwhile.
As for terminating... only a few signals can be caught, I will try to
set them up in order to stop in a sane state (xrandr -o 0, full
brightness if it's currently 0, and so on).
