At every reboot my screen backlight and my keyboard backlight were set up to maximum level on every reboot.

Reading this article:

How do I set default display brightness?

i've solved the problem with my screen backligth running the script mentioned. But i still having problem with my keyboard backlight.

I've already modified with gksudo /etc/rc.local, writing on it:

echo 0 > /sys/class/leds/asus\:\:kbd_backlight/brightness

and also tryed:

echo '0' > /sys/class/leds/asus\:\:kbd_backlight/brightness

But when I restart the system the keyboardk backlight is set to max again.

I'm running Ubuntu 14.04

  • Semantically there is no difference between those lines, 0 and '0' are both passed as 0 to echo by the shell. Does this line have the desired effect if called on the command line (as superuser)? – Adaephon Aug 21 '14 at 20:41
  • When I edit /etc/rc.local and make gksudo it has effect. But when i reboot my keyboard backlight is at maximum again. – Julian Zelayeta Aug 22 '14 at 23:07
  • For me you solution works. Tested on U14.04 Asus ROG G73SW – Waldemar Wosiński Oct 16 '14 at 4:26
