Affected from this bug as well, cant control games with xbox360 wirelesss when streaming from linux to linux.

Having the same problem when streaming from my desktop PC to my HTPC.
Can control Big Picture, but streamed games are not responding to my controller. Have to plug the controller directly into the host.

Have tried it with XCOM: Enemy Unknown and Portal 2.

Just managed to make the controller work by allowing the Steam client on the host to be able to read and write to a specific "character device." The issue is actually described under known issues already.

This may not be the best solution, but to make it work, this is what I did:

1. Started a terminal
2. sudo chmod o+rw /dev/uinput
3. Restarted Steam on host and client for good measure

Note: not sure if this change will still be there after a reboot.

Just some thoughts - steam should probably scan for this and tell the user that there will probably be issues when streaming with a controller, and perhaps give a hint on how to fix this.

Yeah.. looks like changing /dev/uinput read/write permissions solved it, this works until reboot.thanks. But i dont think this workaround is the way to go for the average steam user. =/

AFAIK, udev rules can be changed for gaming input devices i/o files
under /dev to be writable.

I found this thread as I am having this issue. My joystick works in Steam on both the client and server (both GNU/Linux boxes) but does not work in game when streaming.

I will test this chmod solution tonight when I have a chance and comment whether the solution solves the problem for me.

Thank you.

I have confirmed that chmod o+rw /dev/uinput works for me as well.

This issue is likely outdated. I am able to control a game on my deck with a controller connected to my PC.
