Running hardware accelerated app in nvidia jetson nano docker container

Hello,

Following the instructions at https://github.com/NVIDIA/nvidia-docker/wiki/NVIDIA-Container-Runtime-on-Jetson i am doing some tests for running GUI apps in a docker container in a jetson nano, i’m using the following code to do the tests:

    docker run --runtime nvidia --network host -it -e DISPLAY=$DISPLAY -v /tmp/.X11-unix/:/tmp/.X11-unix nvcr.io/nvidia/l4t-base:r32.4.3
     
    apt-get update && apt-get install -y mesa-utils
   
    export DISPLAY=:0.0 && glxgears

everything works well, in this example i run the container in host mode (–network host) but i have an application where i want to run the container isolated from the host, after i remove --network host and run the container, doing the same steps i got the following error:

root@056440576e00:/# glxgears 
Segmentation fault (core dumped)

the strace log:

gdb log:

why i’m getting the segmentation fault only running in the isolated mode. Maybe i have to mount other things besides /tmp/.X11-unix/:/tmp/.X11-unix

the host is running yocto using the dunfell-l4t-r32.4.3 branch from meta-tegra
