XRT_ERROR_NOT_IMPLEMENTED When Running Server w/ WiVRn

I'm attempting to run stardust-xr-server and connect via WiVRn with my MQ3. I've tried different permutations of X11, Wayland, server installed via the AUR or compiled from source. I get the same error each time. Here is an excerpt:

I am able to run other XR apps. Any ideas on how I can troubleshoot this further? EDIT: The solution for me was 2 steps: 1. Apply this https://discord.com/channels/647222689777582080/659858947896770590/1306426347647668256 patch to WiVRn by placing it in pathces/monado before building. 2. Provide the following env vars when running the server,

env __GLX_VENDOR_LIBRARY_NAME=mesa __EGL_VENDOR_LIBRARY_FILENAMES=/usr/share/glvnd/egl_vendor.d/50_mesa.json MESA_LOADER_DRIVER_OVERRIDE=zink GALLIUM_DRIVER=zink stardust-xr-server

Thanks to @Schmarni for all the help! It sounds like this issue only appears in the 550 Nvidia driver.

what gpu are you using? if its nvidia, what driver version are you using?

shneeOP•2mo ago

I'm using the RTX 4070 and the driver version is 550.144.03

Schmarni•2mo ago

ah, are you able to easily update to 565? if not you need to patch monado by dropping a patch file into a folder and rebuilding wivrn

bubbly_fawn_96545•2mo ago

What's the issue with the driver? This looks more like an error with the IPC.

Schmarni•2mo ago

on older drivers stardust crashes the runtime which causes the ipc errors here

shneeOP•2mo ago

looks like im stuck on 550 for now. Is this the patch I need? https://discord.com/channels/647222689777582080/659858947896770590/1306426347647668256

Schmarni•2mo ago

yes that one, just drop that in patches/monado and rebuild it might give you subpar performance when compared to an updated driver, but at least it works

shneeOP•2mo ago

awesome. i will give that a shot and report back. Thank you After applying the patch the server no longer crashes. However, I can't see anything in the headset. I admit I don't really know what I'm doing trying to launch apps in stardust. I created a script that mimics telescope and I run the server with stardust-xr-server -o 1 -e ./telescope-manual.sh. This is the output I get:

Any ideas?

Schmarni•2mo ago

can you try to put

env __GLX_VENDOR_LIBRARY_NAME=mesa __EGL_VENDOR_LIBRARY_FILENAMES=/usr/share/glvnd/egl_vendor.d/50_mesa.json MESA_LOADER_DRIVER_OVERRIDE=zink GALLIUM_DRIVER=zink

infront of your command? that is needed under 565 under wayland for some reason, never needed it before tho

Nova•2mo ago

oh joy this again can't wait to bevy this

shneeOP•2mo ago

SUCCESS! Thanks a ton @Schmarni!

I'm having a very similar (i think?) issue on my meta quest 2, it is giving me XRT_ERROR_NOT_IMPLEMENTED via wivrn. My log reads slightly differently to shnee's, saying

I have applied the patch and env vars and the issue still persists, I just don't normally ask for help myself online so I'm not sure if i should create a new thread for this or not. Some other things to note are i am using an nvidia quadro m2200, with a driver version of 570.124.04

Schmarni•5w ago

those errors don't matter, does it not render or something?

:3•5w ago

yeah, nothing at all happens on either my laptop or headset

Schmarni•4w ago

are you using the open kernel modules or closed?

:3•4w ago

i'm on closed nvidia modules, that's what i'm meant to use right?

Schmarni•4w ago

Well i use the proprietary drivers with the official open kernel modules, but idk if your card is supported on that do you have a multi gpu setup? if yes i might have a workaround in the works

:3•4w ago

my laptop is on two gpus but even when i switched to discrete it is still not working

Schmarni•4w ago

stardust isn't able to select the correct gpu apparently, can you try the steps here? https://discord.com/channels/647222689777582080/659858947896770590/1347666323014025367 you might have to change the path for the dri tho

:3•4w ago

alright sorry it took a moment to try it out, running that branch with /dev/dri/renderD129 simply causes wivrn to my headset to crash, but running it with renderD128 (what is actually in my /dev/dri directory) doesn't crash it, instead it just causes the headset to go full passthrough (all i can see is the camera output) and spam this error message in the terminal:

2025-03-07T22:53:33.358482Z ERROR tokio-runtime-worker smithay::backend::renderer::gles: 355: [GL] GL_INVALID_FRAMEBUFFER_OPERATION in glDrawElementsInstanced

2025-03-07T22:53:33.358482Z ERROR tokio-runtime-worker smithay::backend::renderer::gles: 355: [GL] GL_INVALID_FRAMEBUFFER_OPERATION in glDrawElementsInstanced

so i realised that i had my graphics set to discrete, but after changing them back to hybrid and using /dev/dri/renderD129 i am back to my initial issue i checked just the base stereokit rust example on my headset because i assumed that was the issue and it seems to run flawlessly? i'm not too sure what's going on but this makes it more confusing i think (this was with discrete graphics and no SK_GPU_DRI_PATHset)

Schmarni•4w ago

huh, interesting, so it is something in the stardust server it self

spcecat•3w ago

im having a (kinda similar) issue as i mentioned yesterday in #general-and-development so today i installed a completely fresh arch install with sway (running on gpu using --unsupported-gpu as proven by nvidia-smi output), installed the latest nvidia drivers (570.133.07) and the latest monado-git as well as the latest stardust-xr-telescope from aur, running it with the following envs:

XR_RUNTIME_JSON=/usr/share/openxr/1/openxr_monado.json EGL_PLATFORM=wayland __EGL_VENDOR_LIBRARY_FILENAMES=/usr/share/glvnd/egl_vendor.d/10_nvidia.json __NV_PRIME_RENDER_OFFLOAD=1

XR_RUNTIME_JSON=/usr/share/openxr/1/openxr_monado.json EGL_PLATFORM=wayland __EGL_VENDOR_LIBRARY_FILENAMES=/usr/share/glvnd/egl_vendor.d/10_nvidia.json __NV_PRIME_RENDER_OFFLOAD=1

this still results in the same error as on ubuntu 24.10 with the older 570.124.04 driver (then under gnome wayland)

ERROR [ipc_compositor_get_reference_bounds_rect] ipc_call_compositor_get_reference_bounds_rect failed: XRT_ERROR_NOT_IMPLEMENTED [/usr/src/debug/monado-git/monado/src/xrt/ipc/client/ipc_client_compositor.c:868]

/usr/bin/telescope: line 3:  3595 Segmentation fault      (core dumped) stardust-xr-server -o 1 -e "$(which _telescope_startup)" "$@"

its also worth noting that im running monado with the following env:

XRT_COMPOSITOR_FORCE_XCB=1 XRT_COMPOSITOR_XCB_FULLSCREEN=1 __VK_LAYER_NV_optimus=NVIDIA_only XRT_COMPOSITOR_COMPUTE=1 DRI_PRIME=1

XRT_COMPOSITOR_FORCE_XCB=1 XRT_COMPOSITOR_XCB_FULLSCREEN=1 __VK_LAYER_NV_optimus=NVIDIA_only XRT_COMPOSITOR_COMPUTE=1 DRI_PRIME=1

as it segfaults when trying to aquire direct mode to my hmd, which is a monado issue so i wont dwell on that here :3

that error doesn't matter, something else is failing, i believe stardust (and other stereokit based apps) currently don't really work on multi gpu setups, this should hopefully be fixed in the not to distant future when we switch to bevy for rendering

spcecat•3w ago

ok, also i tried your "nova" branch, this time it doesnt segfault but i just get a fully black screen i still wonder why monado is failing tho :(

Nova•3w ago

that's true, multigpu is broken we're going to replace GL entirely with vulkan to fix the issue but as you can imagine, this takes time...

spcecat•3w ago

ahh gotcha! well best of luck to you, my vulkan skills are zilch

Nova•3w ago

me too tbh trying to just plug it into bevy
