Correction

3.1 Look for brightness and/or backlight in /sys
   find /sys -name "*brightness*" -o -name "*backlight*"

Most likely you will have files similar to

ls /sys/devices/pci0000:00/0000:00:0c.0/0000:02:00.0/backlight/acpi_video0/

  brightness   actual_brightness  max_brightness

You will have /sys/class/backlight, as well
Note that the /sys/class/backlight/acpi_video0 (or similar) should point to the
above entry


Cheers
Emil
