This guide is meant for those using Linux and wanting to use a PS5 Controller (Dualsense) with Chiaki to enable remote play for PS4/PS5.
If you're using a Steam Deck, check out the great chiaki4deck project instead.
Despite the PS5 Controller support added to the 5.12 kernel, I had issues getting it to be recognized by Chiaki.
I've only verified these steps on a PopOS 21.10 (Ubuntu derivative) system, running on 5.16 kernel.
If you have an alternate solution for Linux that worked for you, leave a comment to help others out!
