Cachyos-update Ally X controllers stopped working

[titanmax]

I’m using the Handheld Edition on my Ally X. Everything was working fine until I upgraded a couple of days ago. Now, the Ally X’s built-in controller is no longer being recognized.

[CachyLogo] Hello and welcome to the wonderful world of CachyOS! While Cachy makes it look pretty easy to run an Arch-based system, well… it still is an Arch-based system and that means you are the maintainer and administrator of your own operating system. Which is cool, but with great power comes great responsibility, so before you jump straight into ricing your system, here are some topics you might want to look into first. This list is not comprehensive and probably partly objective, but …

I have the same problem on rog xbox ally x..

I loaded a snapshot from over 12 hours ago, I’ll wait to do the updates via cachy-update as it was working fine before doing them earlier..

[unnecessary_feelings]

I have this problem too on the Xbox Ally X. I can’t interact with any UI at all so the system is basically unusable without an external keyboard. I hadn’t updated in around 4 days and the issue was caused by an update today.

Edit: Found the solution here! Steam v1.0.86 fails to detect ROG Ally built-in controller; v1.0.85 works perfectly · Issue #615 · ShadowBlip/InputPlumber · GitHub . Seems to be caused by a regression in the Steam client. Running this command:

busctl call org.shadowblip.InputPlumber /org/shadowblip/InputPlumber/CompositeDevice0 org.shadowblip.Input.CompositeDevice SetTargetDevices as 1 xbox-elite

in desktop mode solves it temporarily until a system reboot. Someone’s made a service to apply the fix automatically upon boot here: GitHub - DeadRuins/Xbox-Ally-X-InputPlumber-D-Bus-Fix: A little haphazard Input Plumber fix script for when the controller suddenly stopped working. · GitHub

These worked for me on the Xbox Ally X, not sure if they’ll work on the base Ally.

Please roll back the steam-device version of Steam to 1.0.85
The Steam update upgraded controller authentication, which caused verification failures for Deck controllers.
