This is a rough cut at documenting stuff as I find it.

/sys/class/backlight/gta01-bl is a directory containing:

filename description
actual_brightness reports on current set brightness. (0-5194)
max_brightness Maximum possible brightness
subsystem
uevent ?
brightness dim with something like:
echo 1000 > /sys/class/backlight/gta01-bl/brightness 
power Turn backlight off with:
echo 1 >/sys/class/backlight/gta01-bl/power
and turn on with:
echo 0 >/sys/class/backlight/gta01-bl/power

/sys/class/leds/gta01:vibrator/brightness -

  • turn vibrator on:
echo 1 >/sys/class/leds/gta01:vibrator/brightness
  • turn vibrator off:
echo 0 >/sys/class/leds/gta01:vibrator/brightness
Personal tools
