Hello,
No idea why this is happening, as apparently no one else is having this issue, but my PS5 controller does not work with linux. I did a clean install of Mint today, and on my old install it was working great. Now, Steam recognizes the controller, testing the inputs shows everything works, and Linux recognizes the controller is connected with the USB, but it is not registering with any game. None of the inputs work, and even more annoyingly pressing the PS button immediately launches steam big picture mode, which I do not want.
I’ve been trying for hours to fix this and everyone else is saying it works great out of the box, but that is the opposite of the case for me. Any advice?
For me connecting it to a Windows machine and updating the controller firmware made it works. Apparently you could do that using Bottles (wine) directly on your Linux distro.
