I tried just before the bug report submission to alter the backlight with function keys, the backlight indicator shows up and percentages change but light does not. I have a asus zaphyre g16 rog with 4080 nvidia laptop.
I am not quite sure, but you likely need a kernel patched with asus-linux patches for ROG keyboard backlight support. See: https://asus-linux.org/
Hello! Firstly, thanks for an awesome linux distro. I absolutely love it.
Thank you I will see if the asus custom kernel solves it
