/dev/dri/renderD128 permission denied. (with aside)

I first had an error log much longer than this .I installed the Nvidia drivers, composed down and back up to see this. I’m weary of changing permissions of my device. But i do find it odd that the other image logs aren’t showing up in the log.

also also I’ve been building a GTK / broadwayd proxy server which led me to this project . Though I have not yet mounted GPU into my containers I also get EGL failures ( on different machines ) . I wonder what I’m missing here.

You need to install and configure the nvidia container runtime on the host and set the appropriate permissions inside the container (this won't affect the permissions on your host machine). To do just that, I've modified the docker-compose file with relevant parts commented out this PR: https://github.com/udevbe/greenfield/pull/115/files#diff-16cc61697a8e7853bc71730a86d3382f3de88553247418f6e572b0386018c0a4

I appreciate the reply … you are 100% correct (as well you know). I found this out shortly after my issue post and forgot to append.
