There are a few co-op games I'd like to play with family/friends, but since it's not possible to use separate machines for all games and they do support controllers, I would like to allow the second player to use the controller (there is only one in the house, a wired Xbox 360 controller). But the problem with that is that most games force controller #1 to be player #1, but the keyboard and mouse would also be player #1. Thus, the controller and keyboard will be fighting to control the same player.
I have no idea if this will allow me to play local co-op games with only one controller, but if I could force the controller to become controller #2, I could at least experiment game-by-game what would work with that.
So can I, in Linux (Ubuntu 16.10 or Debian Stretch), force a single wired Xbox controller to be controller #2?
