I've looked at various guides and tools for adjusting the keyboard backlight brightness of my Asus G531GT laptop on Linux. All (e.g. https://github.com/iamweird/asus-kbd-backlight) seem to work by editing a configuration file for backlight brightness. The most common configuration folder is /sys/class/leds/asus::kbd_backlight.

However on my machine (with Pop OS/Ubuntu 19.04) I do not have such a folder. I do have /sys/class/leds with other subfolders, and I can use them to set the brightness of other leds on my machine, like the Caps Lock LED.

Does anyone know how to fix this?

I discovered a project which allows to control the keyboard backlight for ROG laptops: https://github.com/wroberts/rogauracore. After installing you can do sudo rogauracore black to turn off the backlight. You can also configure the lighting in similar ways to the Windows Aura Core software.

However I don't know whether the backlight can be dimmed with this project.
