Simulator: LGSVL does not start on Ubuntu 20.04

[kmitri-dxc]

When starting the pre-compiled version downloaded from the release 2020.06, I run the simulator, a black screen appears and then goes away.

Thanks for the debug logs, it is very helpful. Did you see this?

Vulkan API version 1.1.0 (1.2.131 supported by driver)

Vulkan renderer=[Intel(R) UHD Graphics 630 (CFL GT2)] id=[3e98]

This looks like you are running the application with the Intel, not the nvidia GPU. Please try to force the application to use the GPU. One way is in the Nvidia control panel, force LGSVL Simulator app to use GPU not Intel. Hope this helps

[mjshiggins]

@EricBoiseLGSVL Oddly enough, I just started experiencing this today. I'm not sure what could have changed to start causing this across different users, but what is the standard way to force the Nvidia GPU (I'm personally using LGSVL inside a Docker container)?

[EricBoiseLGSVL]

Not sure on Linux, I use Windows ;) @lemketron or @zelenkovsky
On windows I use Nvidia Control panel

[kmitri-dxc]

Thanks @EricBoiseLGSVL, I couldn't figure out how to force it to use the NVIDIA GPU, but It worked well in a docker container using NVIDIA Container Toolkit.

@mjshiggins Install Nvidia Container Toolkit and run docker with --gpu all.

[shr-project]

It works for me in Ubuntu 20.04 with docker, but I have just 1 GPU in the system:

$ nvidia-container-cli info
NVRM version:   450.80.02
CUDA version:   11.0

Device Index:   0
Device Minor:   0
Model:          GeForce GTX 1060 6GB
Brand:          GeForce
GPU UUID:       GPU-5fdec0a6-ada0-70ed-c6b4-bce14668482f
Bus Location:   00000000:01:00.0
Architecture:   6.1

Maybe you can restrict NVIDIA_VISIBLE_DEVICES to include the id of your nvidia card, so that it doesn't expose the intel one in docker?
