The game supports Vive-like (including Index) controllers only, because the oculus executable depends on the oculus runtime thus does not run on Linux. But if you use ALVR for streaming to e.g. Meta Quest 2 or Meta Quest 3, you can change the controller emulation to be for Vive Wands or Valve Knuckles and the game will work correctly. As it also accepts mouse and keyboard entries, you can also map your controllers via steam input to work.
