While playing Dead Cells from Steam, I noticed than when I was hurt, my controlled was somehow disconnected for a few seconds (with an alert message saying so). In this case, the game run a bunch of vibration. If I disable them, it works without trouble. To confirm this, I ran evtest and fftest as said in the post: How to enable a vibration in a PC gamepad in Xubuntu 18.10. Here is my output:
$ evtest

So my controller is at /dev/input/event25 and supports rumble.
$ fftest /dev/input/event25
Force feedback test program.

Here No such device speaks wonder. My controller was indeed disconnected somehow.
I read the arch wiki and found this:
If you experience problems with the rumble feature not working in games, it may be necessary to set the environment variable SDL_JOYSTICK_HIDAPI=0
So following How do I set a user environment variable? , I edited /etc/environment with SDL_JOYSTICK_HIDAPI=0. Then, I rebooted. No success here.
I also try with the xboxdrv as propose in the wiki without success either.
