RVIZ2 not using GPU

[ryan-roche]

I'm running RVIZ2 inside a docker container with GPU enabled. The container is running on the docker engine installed inside WSL2 (I manually installed the docker engine inside the WSL2 VM as I was not able to get my GPU working with Docker Desktop on Windows).

nvidia-smi and glxgears work inside the container, so the GPU driver is properly "exposing" itself to the container. However, RVIZ runs slowly and nvidia-smi does not show it in the process list. The only process reported by nvidia-smi as using the GPU (even when RVIZ is running) is XWayland. SOS!!!

Running Linux docker containers on Windows without WSL2 is not supported, but you appear to have solved that issue. 👍🏾

You can force an application to run using the nvidia gpu by using Nvidia's PRIME on linux. Is there a specific reason you want to run rviz in a container? If you need reproducibility it may be simpler to write a setup script.

This question on StackExchange is helpful.
I had the same problem, but I solved it.
I followed the answer in that question and added additional options to docker and then Rviz2 started using the GPU.
