GPU not found


we have setup out first render server now. But at the moment we have some trouble to proper install omniverse enterprise under linux, so we decided to install windows server 2022 and use Omniverse Workstation for our first test and switch later to Omniverse Enterprise on linux.

The system has two A40 graphic cards and we have installed the latest drivers. But when I start Create it just shows the splash screen and then stops.

Following messages are written to the log file…

  • The driver is not installed properly and requires a clean re-install.
  • Your GPUs do not support RayTracing: DXR or Vulkan ray_tracing, or hardware is excluded due to performance.
  • The driver cannot enumerate any GPU: driver, display or a docker issue. For Vulkan, test it with Vulkaninfo tool from Vulkan SDK, instead of nvidia-smi.

Can anyone help with this? It looks like kit does not reconize the A40s as RTX devices and recognize it as “Microsoft Basic Render Driver”. But the driver is installed…


Thanks for your help

@mati-nvidia can you have a look at this? We have bought a render server with two A40s and now we could not use kit… and do not have any clue whats the problem…
