+# Installing Nvidia Drivers for Docker
+
+If you are **not** using a virtual machine (you run Ubuntu LTS directly on your computer), and you have an nVidia graphics card, you can get 3D-accelerated graphics according to [these instructions](https://github.com/NVIDIA/nvidia-docker). 
+
+Alternatively, do the following (though the web page linked above may be more up to date):
+
+```bash
+# Add the package repositories
+distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
+curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey | sudo apt-key add -
+curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.list | sudo tee /etc/apt/sources.list.d/nvidia-docker.list
+
+sudo apt-get update && sudo apt-get install -y nvidia-docker2
+sudo systemctl restart docker
