Gnome - turn on keyboard's leds before login

Hi guys.
I'd like to turn on the leds of my keyboard (CM Devastator) before the login of the user: i've inserted the command "xset led 3" into /etc/gdm/Init/Default but it does not work, does someone know why?

No clue, but you are aware setting the leds is not the same as activating their function ?

If this happens to be the numlock setting, check https://www.archlinux.org/packages/comm … /numlockx/

I've already installed numlockx but it does not help.
Just to be clear, for keyboard's led i mean the leds under the buttons of the keyboard.
example

I can't find anything strange in the journal's log, i post it if someone wanna give it a look.

Good day

Did you see the wiki page about this issue? [https://wiki.archlinux.org/index.php/Keyboard_backlight]
I dont know if it works, but have some options.

Re: Gnome - turn on keyboard's leds before login

output of

$ systemctl status upower.service

Does the bash oneliner mentioned in the wiki work ?
