I wound up with one of those newfangled playstation controllers, and I’m surprised at how good it is. It paired nicely on Endeavour KDE, and there’s a big touchpad in the center that works to control the mouse pointer out of the box. I’m quite happy with it!
That’s because there is an official Sony driver for the controllers in the Linux Kernel for some time now.

It is really great how good the controller works, I use it via USB-C and just love it.
