Xbox One controller not working on Linux

[inr]

I'm trying to play the game using an Xbox One controller plugged in with a micro usb cable. The controller works fine in Big Picture mode and other games (e.g., VVVVVV), but I'm getting no response in Stephen's Sausage Roll (except rumble works). The game works fine with a wired Xbox 360 controller.

The controller seem to be using the xpad driver:

[48965.725454] usb 3-1.2: new full-speed USB device number 23 using xhci_hcd
[48965.818822] input: Microsoft X-Box One S pad as /devices/pci0000:00/0000:00:14.0/usb3/3-1/3-1.2/3-1.2:1.0/input/input33
[48967.314871] input: Microsoft X-Box 360 pad as /devices/virtual/input/input34

Not sure why it registers as two controllers, possibly this is causing the issue?

Is this a game issue or a Steam issue? Is it possible to fix?

Rumble works but input doesnt? Oh dear.

Have you tried out the latest beta branch? (104 or whatever) it might work better for you. (if you don't know how to change branches see https://steamcommunity.com/app/233610/discussions/2/490123197937180301/ ).

There is a known problem with people who have multiple controllers plugged in - it's not smart (that's my bad) and always tries to read controller 1 IIRC.

Thanks for the suggestions. I've tried both beta104 and testing and they exhibit the same issue. I only ever have one controller plugged in, the Xbox 360 controller comment was about unplugging the Xbox One controller and plugging in the 360 controller.

But it sounds like the driver registering two controllers can be a source of trouble. Apparently there are other reports, though the result is different with every input being registered twice instead:

Probably no use, but some output from when starting Steam and the game (removed a bunch of noise):

You're lucky at all to have it working. My xbox one controller doesn't work at all in Big Picture nor anywhere on Linux. Big picture shows 4 xbox360 controller connected however while I have no such thing. Even if the controller would be detected, I never understood, in over two years now, how to map the buttons on this awful Big Picture controller interface. I'm pretty sure half of the users with a gamepad just give it up at some point and use a keyboard instead.

That's unfortunate. Hopefully the controller keeps working. As a workaround I configured the controller in the Steam interface to simulate keyboard input. It works alright since the game doesn't really depend on precise input.
