I have dual booted Windows 10 and Ubuntu 18.04LTS on 2 partitions of my SSD respectively.

The default red keyboard backlight comes on for a few seconds during BIOS startup but then disappears before GRUB menu.

No luck using xset led 3 on terminal. No scrollkey on keyboard so I guess that isn't an option. Tried using the following bash file (got it from another question on Ask Ubuntu) but no luck:

I ran this using ./lights.sh

xset script

On Windows I used to use a program called Lenovo Nerve Sense to control my RGB keyboard backlight. Perhaps we can configure it using Wine for Ubuntu?

I've already referred to this question: Lenovo Legion Y720 laptop Keyboard backlight

But this is not the right way of dealing with this problem. Also it doesn't work for me.

Your help would really be appreciated!

I made a software that controls the Lenovo Legion Y720 keyboard backlight.

https://github.com/Izurii/Lenovo-Y720-KB-Led-Controller

It's made for Linux and right now it's working with Ubuntu 20.04

Lenovo Y720 KB LED Controller Releases

You can download and run the latest AppImage and change the keyboard settings or you can download de DEB package and install using sudo dpkg -i package-name.deb in a terminal, the software starts at login so you don't need to open every time you restart your PC, and the global hotkey Fn+space (the same used in Lenovo Nerve Center) is working.
