Hi I have recently installed and using Manjaro with DE XFCE.4.16 on my ASUS TUF Gaming FX705DT laptop. I do not have windows installed on this laptop, and only using Manjaro as my primary OS. After installing Manjaro I noticed my back-lit keyboard’s RGB backlight is not working. Need help on this issue.
I am fairly new to linux so any help and guidance will be much appreciated.
Below are few details about my system:
bios version I am using is 316, which is the latest one as per asus support page.
