Thanks for the issue @rsignell-usgs! Thanks for sharing the link on how this might be configured. Looks like we are running a virtual frame buffer in the background that programs can render graphical windows into. This reminds me of similar requests for having desktops within jupyterhub in docker containers similar to https://hub.docker.com/r/alsadi/containerized-xorg-spice/.

Looks like then you'd like to have

sudo apt-get install libgl1-mesa-dev xvfb

included in the docker image and then users would run pyvista.start_xvfb(). We currently have mesa already installed but not xvfb.
