OK, here's what I did:
# cat /sys/class/backlight/intel_backlight/brightness
4437
# echo 4335 > /sys/class/backlight/intel_backlight/brightness
Then I closed the lid and opened again, with the screen not resuming. On
secondary screen I did:
# cat /sys/class/backlight/intel_backlight/brightness
0
# echo 4335 > /sys/class/backlight/intel_backlight/brightness
And after that screen turned ON</pre>
