I'm unable to turn off backlight of my keyboard. I've tried every solutions available on the internet including xset, etc. But nothing seem to work on AsusFX503. I've Ubuntu 18.04 installed. Please help.
I found the
rogauracore package on Github here: https://github.com/wroberts/rogauracore. On my G531GT it allowed me to control the color of the backlight, which included turning it off. I can't easily dim the backlight, but I can choose a color which is less bright, effectively dimming it, although not as convenient.
It's not the real solution to the problem (which probably involves some kernel update), but a very useful workaround with the added bonus that you can actually control the RGB on the backlight too.
