Hello, I am trying to turn off screen using sysfs entries, but I'm having some difficulties with it: 1. command: echo 0 > /sys/devices/platform/s5p-dsim.0/ea8061/backlight/panel/brightness result: screen is dimmed - BUT not turned off 2. command: cat /sys/devices/platform/s5p-dsim.0/ea8061/backlight/panel/actual_brightness 20 This strengthen the fast that we didn't turned off brightness completely 3. In this point I though that maybe I can turn off the whole brightness device ls /sys/devices/platform/s5p-dsim.0/ea8061/backlight/panel/ actual_brightness auto_brightness bl_power brightness device dimming max_brightness power subsystem type uevent I made some trials , but didn't made it turned off yet. Is there any idea if it's possible to turn it off completely ? Thank you, Ran
