Keyboard backlight

Hi guys, I’m new to hyprland and arch based distros. I’m running the latest version of cachyos with hyprland 0.55.2

I have problems making the keyboard backlight work, i added this line

hl.bind(“scroll_lock”, hl.dsp.exec_cmd(“brightnessctl –device=’input6::scrolllock’ set 1)

to the configuration file to bind the key and the led, and it works, but whenever i press another key after, the led turn back off.

I don’t know if is a problem of hyprland or cachy but anyone knows a way to keep it on?

if usefull the keyboard is a devastator 2 model SGB-3032-KKMF1-IT of cooler master.

sorry if there are grammar error but english is my second language
