Actually, they do! Now the Grace isn’t exactly something you’d plop into your desktop PC, but it’s certainly a CPU. I think they’ve made others too, and a new model (Vera) is coming.

I’ve been using input-remapper with my Naga for a long time, so it should work (Tumbleweed with Wayland). But the software is quite quirky and can be a bit of a pain to setup and learn. Hope you manage to figure it out!
