14. As root, I tried

echo 8 > /sys/class/backlight/intel_backlight/brightness

Voila! Finally it is doing something. This made the screen almost too dim to see.

echo 1000 > /sys/class/backlight/intel_backlight/brightness

This made the display usable again.

The next step involves rebooting again... I'll be back shortly.
