This docker image allows you to run a X server with VNC within docker. Based on Debian Bullseye (Slim)
When you first start the docker-compose file and you successfully connect via VNC, you'll see a black screen.
This is because that is how a minimal X server setup without any DE, WM or Window looks like.
This image is a bare minimum setup, you'll have to provide the WM yourself.
An example with DWM and ST can be found here.
If you have any questions, just raise an issue and I'll respond as soon as I can.
This repo is strongly based on suchja/x11server, thanks for the original version!
