# docker-nvidia-glx-desktop

MATE Desktop container supporting GLX/Vulkan for NVIDIA GPUs by spawning its own
X Server and noVNC WebSocket interface instead of using the host X server. Does
not require `/tmp/.X11-unix` host sockets or any non-conventional/dangerous host
setup.

Use
[docker-nvidia-egl-desktop](https://github.com/ehfd/docker-nvidia-egl-desktop)
for a MATE Desktop container that directly accesses NVIDIA GPUs without using an
X Server (without Vulkan support).

Corresponding container toolkit on the host for allocating GPUs should be set
up. Container startup should take some time as it automatically installs NVIDIA
drivers.

Connect to the spawned noVNC WebSocket instance with a browser in port 5901, no
VNC client required (password for the default user is 'vncpasswd').

Note: Requires access to at least one **/dev/ttyX** device. Check out
[k8s-hostdev-plugin](https://github.com/bluebeach/k8s-hostdev-plugin) for
provisioning this in Kubernetes clusters without privileged access.

For Docker this configuration is tested to work but the container will have
potentially unsafe privileged access:

```
docker run --gpus 1 --privileged -it -e SIZEW=1920 -e SIZEH=1080 -e SHARED=TRUE -e VNCPASS=vncpasswd -p 5901:5901 ehfd/nvidia-glx-desktop:latest
```

The below may also work without privileged access but is untested:

```
docker run --gpus 1 --device=/dev/tty0:rw -it -e SIZEW=1920 -e SIZEH=1080 -e SHARED=TRUE -e VNCPASS=vncpasswd -p 5901:5901 ehfd/nvidia-glx-desktop:latest
```
