I have a Lenovo Y720 that has a backlit keyboard. However, Lenovo choose to not have the light built into the actual firmware, but instead make it dependant on a program called Lenovo Nerve Sense, which is not open source and only runs on Windows. So far I used to boot up Windows on my PC, run the program, and then boot into Ubuntu. The keyboard light would stay as long as I never turned the laptop off (suspend is fine). This makes me think that the keyboard light runs in the RAM. This solution however is very tiring as I can never shut the laptop off or I would have to boot Windows up again. I know that a virtual machine does not have access to the hardware and therefore running the program in a VM does not work, the same thing goes for Wine.

So my question is, is there any possible way that I could actually run this program on Ubuntu so my keyboard light can turn on?

I have searched the web for 2 years, asked multiple questions and tried all of the solutions I could find, no solution works, as all of the solutions I have seen are for laptops that have the light built into the firmware and therefore a command like "xset led 3" works, but not for me.

Here is a list of what I have tried:

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

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

Lenovo Y720 KB 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.
