[Bug]: Quest2 Right Controller input in Half Life: Alyx is broken

Operating System

Pop!_OS 24.04

OpenXR Runtime

WiVRn

Describe the issue.

When playing Half Life: Alyx my right Quest2 controller does not fully function (only trigger and grab).

I've done a clean install of my OS, I've even replaced the thumbstick (was starting to drift so needed replacing anyway).

Both controllers fine and fully functional in Meta Horizon home and ALVR.

Experienced behavior below.

Left controller:
Works exactly as expected.

Right controller:
I can see that the grab and trigger input is picked up and reflected by the virtual hands.
Capacative proximity is detected on the right trigger.
No capacative input is detected on A/B buttons or stick at all.
Flicking the right thumbstick left or right would usually turn you, nothing happens.

My Steam cloud saves did not restore with my OS re-installation for some reason so I am unable to check right controller button presses (A/B) as I'm not at a stage in the game where they are used, but before I re-installed they seemed to pick up iirc.

Using xrizer nightly (as of 18th December 2025)

I also experience the same in The Lab as well fwiw.

Valve's games use SteamVR-only features extensively that are hard to replicate in xrizer. In this case, it's action set priorities. This currently can't easily be integrated in xrizer as that would break xrizer's hand skeleton estimation, which would affect more than just a handful of games.

There was a working solution that ended up not being merged due to the Monado team instead wanting to have skeletal estimation in Monado itself. And so, we are now waiting for Monado to add skeletal estimation support.

If you are good with C, please consider helping implement skeletal hand estimation in Monado.

Thanks for your response. Unfortunately I am only proficient in Python (and then only in my capacity as a VFX TD).

So am I right in assuming that nobody is able to successfully play HLX using wivrn and xrizer? Seems odd to me that more people are not encountering this. I thought perhaps my setup was cursed.
