First question - is there likely to be support for RTX 4070 for CloudXR Runtime for use with CloudXR.js?

Second - I have switched to a cloud Linux instance for testing but receive errors regarding a missing monado-service binary:

Environment:

  • OS: Ubuntu 22.04 LTS (Nebius cloud “Ubuntu 22.04 for NVIDIA GPUs (CUDA 12)” image)

  • GPU: NVIDIA L40S (device ID 0x26b9) — confirmed on CloudXR 6.0.5 supported GPU list

  • Driver: 550.163.01

  • CUDA: 12.4

  • Vulkan: 1.3.277, NVIDIA proprietary ICD (verified via vulkaninfo)

  • SDK: CloudXR-6.0.5-Linux-sdk.tar.gz (downloaded from NGC)

  • Application: NVIDIA’s CloudXR LÖVR sample (uses the SDK as documented)

  • Run mode: --webrtc for Meta Quest 3 streaming

Symptom:

When running the sample, the CloudXR runtime fails to start with:

Active user not found. Using default user [kiosk]
Failed to start service (result: -2)
Failed to start CloudXR service (this is expected if CloudXR runtime is not available)
ERROR [ipc_client_socket_connect] Failed to connect to socket /run/user/1001/ipc_cloudxr: No such file or directory!
ERROR [ipc_client_connection_init] Failed to connect to monado service process

###
#
# Please make sure that the service process is running
#
# It is called "monado-service"
# In build trees, it is located "build-dir/src/xrt/targets/service/monado-service"
#

XR_ERROR_RUNTIME_FAILURE in xrCreateInstance: Failed to create instance '-1'.

Is there expected to be a monado-service binary with this SDK? Where can I find a compatible binary?
