Nintendo Switch Pro controller no inputs

[MysticalJungle]

Hello.

I have a problem.
I tried getting my Switch controller to work on my PC Stick with Linux Mint.

So I pair the controller with Bluetooth and says it's connected.

So I start RetroArch, start a game and it's not registering input.
RetroArch doesn't even recognize it that way.

I also tried connecting it with the USB cable. It's recognized as an Xbox 360 controller in RetroArch. And again, no inputs, can't do anything.

What do I need to do?
I prefer Bluetooth, otherwise I need a really long cable...
