> - On Linux, my Xbox gamepads don't work at all

Really? I use Linux full time at home and I've never had problems with 360 controllers either when developing with SDL2 or playing games built with it. Are you talking about original Xbox and/or Xbox One controllers?

Aftermarket Xbox 360 controllers. I've seen other Linux SDL games work with 360 controllers, so I assume the problem is on my end. I just wanted to contest the notion that SDL "just works". It still takes a lot of fiddling unfortunately.
