My main tool for creating and testing GUI apps inside a container by mounting the X11 directory to the container.

Start with docker (I haven't tested podman, but it should be the same syntex):

docker run -dt --gpus all -e DISPLAY=$DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix --name tilix 1nachi/tilix:

or if you are using nerdctl:

nerdctl run -d --gpus all -e DISPLAY=$DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix --name tilix 1nachi/tilix:
