Help! shared IPC namespace unavailable

Help! Vorpx always gets the same result when running on my computer: openvr runtime error:shared IPC namespace unavailable (310) (310)

Sounds like a SteamVR misconfiguration.

If you don’t have a native SteamVR headset (e.g. Index or Vive), SteamVR is only the third best option anyway. Switch to OpenXR (works with all headsets) or Oculus (only works with Meta/Oculus headsets) in the vorpX config app.

Caveat 1 (for Oculus/WMR headsets): Unfortunately SteamVR tries to make itself the system’s OpenXR runtime no matter what. That is *NOT* what you want when you run an Oculus/WMR headset with OpenXR. Instead use your headset vendor’s native OpenXR implementation.

Caveat 2 (for Index/Vive): While native SteamVR headsets like Index or Vive also work with OpenXR in principle these days, Valve very unfortunately doesn’t seem to be interested in being fully compliant to the OpenXR specs. After more than two years they still didn’t bother to implement OpenXR for 32bit, which in effect limits the SteamVR OpenXR mode to newer 64bit games.

After changing to openxr:

This is a server error.
Make sure that OpenXR is working correctly on your PC or switch to a different VR API in the vorpX config app.

Install other software? Now it work under win11 & steamvr.

Your need to have a valid OpenXR runtime set. What headset do you use? I can’t really help in a more specific way without at least some basic infos.

Thanks for your help!
My device is Pico neo3.
I don’t know more about it.
The following is its official website, which may let you know something about it.

What do you mean by basic information?

headset: Pico neo3
system: windows11
Streaming software: picovr streaming + steamvr
It works correctly by Alex, Moss…
When I choose “steamvr” mod in VorpX:
openvr runtime error:shared IPC namespace unavailable (310) (310)
But I choose “openxr” mod in VorpX:
This is a server error.
Make sure that OpenXR is working correctly on your PC or switch to a different VR API in the vorpX
config app.

Unfortunately I have no experience myself with the headset. Since it appears to be a native SteamVR headset, SteamVR has to be your system‘s OpenXR runtime to use OpenXR.

Usually SteamVR complains if it isn‘t on launch, but you can also enable OpenXR manually in the SteamVR settings.
