You must have TurboVNC installed on your client to use this container for remote vizualization.
VirtualGL is an open source toolkit that gives any Unix or Linux remote display software the ability to run OpenGL applications with full 3D hardware acceleration. VirtualGL is run on both the server and client for sending the display over the internet.
TurboVNC is tuned to provide peak performance for 3D and video workloads.

Ubuntu installation instructions
Download the following packages for the server:
- The .deb package for VirtualGL on sourceforge
- The .deb package for TurboVNC on sourceforge
Install Singularity on your server. As of mid-August 2018 Singularity is v2.6.0
Option 1: Pull this Github Repository and build the container on the server:
git clone https://github.com/tyson-swetnam/turbovnc-singularity
cd turbovnc-singularity
sudo singularity build turbovnc-ubuntu16.simg Singularity
Option 2:: Pull pre-built container from Singularity Hub:
singularity pull --name turbovnc-ubuntu16.simg shub://tyson-swetnam/turbovnc-singularity
The vncserver should start on its own and create a ~/.vnc/xstartup.turbovnc file.
If you are having problems with starting the vncserver, check your VirtualGL installation.
If running on UA HPC, remember to:
module load singularity
module load cuda80/gdk
Run the container (default entrypoint):
singularity run --nv turbovnc-ubuntu16.simg
Execute the container:
singularity exec --nv turbovnc-ubuntu16.simg vncserver -geometry 1920x1080 -dpi 128
Shell into the container:
singularity shell --nv turbovnc-ubuntu16.simg
Start NoVNC and websockify
