Can't Send Image from Isaac-sim to Quest 2 in Collab-sim, Linux

I was testing Collab-sim with:

  • Ubuntu 22.04
  • Isaac-sim 4.5.0
  • Quest 2 VR headset
  • ALVR 20.14
  • NVIDIA Driver 535.247.01
  • CUDA 11.8.9

However, the image of left and right eye shown in Isaac-sim didn’t show on my Quest 2. As you can see in the video, my SteamVR shows what I CAN see in my headset, while my Isaac sim shows what I SHOULD see.


What’s incredible is, Isaac-sim CAN tell where are those controllers, status of their button as well, which means that the information from headset to Isaac-sim is well-done, but on the other hand (from Isaac-sim to headset), it isn’t.

Does anyone have some ideas about this situation?

We will check with our team and get back to you here.

Have you tried the isaac-sim.xr.vr.sh launch script? Could you try selecting OpenXR as the output plugin?
