I was excited to try this out, but on my Ubuntu machine, my Logitech USB gamepad doesn't work. I can navigate, jump, and open my inventory, but I cannot close it and I can't attack. In fact, in a bit of irony, when I navigate to the controller settings (either from the pause menu or from the main menu), I can't navigate away, leaving me forever stuck on the controller mapping page.
Is there anything I can do to help diagnose this issue?
