Ray tracing works on Linux just fine. I don’t know what your talking about. I have software to control the lights on my Asus laptop keyboard if needed, my other keyboard is not addressable RGB anyway. I’ve seen Linux work with controllers too. Maybe not Xbox specifically, though I think there is a way to do that too.

Edit: Logitech keyboards have support: https://pwr-solaar.github.io/Solaar/

There are projects for supporting the Xbox controllers too: https://github.com/medusalix/xone
