/sys/class/leds/* reset after login

Hi

I have a CM Devastetor 2 keyboard, by default backlight is off (screen lock keymap problem).
I created a /etc/tmpfiles.d/cm_backlight.conf

w /sys/class/leds/input15::scrolllock/brightness - - - - 3

After every restart led is actived during systemd loading but after login (xinit) /sys/class/leds/input15::scrolllock/brightness is resetted to "0".

Is there a workaround for this?

You probably want to investigate exactly what is changing the value, if it is xorg after probing/poking the hardware or if it is the DE doing what it thinks you want.

i think the problem is caused by de (kde5).
login in init3 work as expected.
