I'm running Linux and my two controllers are..
- THRUSTMASTER 2-in-1 Dual Trigger Controller
- THRUSTMASTER 3-in-1 Dual Trigger Controller
The problem is that even though I can configure one of them in Big Picture Mode, but neither is there a way to select a controller nor is there a way to configure both of them at the same time. Although I got it working once or twice, but now it doesn't anymore. The is also the case for Guacamelee (and probably many more).
I don't know if it helps, but here is a way to get the configuration that was made my Big Picture Mode.
So, how can I get two (non Xbox) gamepades work consistently on Linux (with Steam) for local co-op?
