jupyter-remote-desktop-proxy 3.0.1

Run a desktop environments on Jupyter

Jupyter Remote Desktop Proxy

Run XFCE (or other desktop environments) on Jupyter.

This is based on https://github.com/ryanlovett/nbnovnc.

When this extension is launched it will run a Linux desktop on the Jupyter single-user server, and proxy it to your browser using VNC via Jupyter.

VNC Server

This extension requires installing a VNC server on the system (likely in a container image). Compatibility with the latest version of TigerVNC and TurboVNC is maintained and verified with tests, but other VNC servers available in $PATH as vncserver could also work. The vncserver binary needs to accept the flags seen passed here, such as -rfbunixpath and a few others.

For an example, see the Dockerfile in this repository which installs either TigerVNC or TurboVNC together with XFCE4.

Installation

1. Install this package itself, with pip from PyPI:

   pip install jupyter-remote-desktop-proxy
   

2. Install the packages needed to provide a VNC server and the actual Linux Desktop environment. You need to pick a desktop environment (there are many!) - here are the packages to use TigerVNC and the light-weight XFCE4 desktop environment on Ubuntu 24.04:

   dbus-x11
   xfce4
   xfce4-panel
   xfce4-session
   xfce4-settings
   xorg
   xubuntu-icon-theme
   tigervnc-standalone-server
   

   The recommended way to install these is from your Linux system package manager of choice (such as apt).

Docker

To spin up such a notebook first build the container:

$ docker build -t $(whoami)/$(basename ${PWD}) .

Now you can run the image:

$ docker run --rm --security-opt seccomp=unconfined -p 8888:8888 $(whoami)/$(basename ${PWD})
Executing the command: jupyter notebook
[I 12:43:59.148 NotebookApp] Writing notebook server cookie secret to /home/jovyan/.local/share/jupyter/runtime/notebook_cookie_secret

    To access the notebook, open this file in a browser:
        file:///home/jovyan/.local/share/jupyter/runtime/nbserver-8-open.html
    Or copy and paste one of these URLs:
        http://924904e0a646:8888/?token=40475e553b7671b9e93533b97afe584fa2030448505a7d83
     or http://127.0.0.1:8888/?token=40475e553b7671b9e93533b97afe584fa2030448505a7d83
*snip*

Now head to the URL shown and you will be greated with a XFCE desktop.

Note the --security-opt seccomp=unconfined parameter - this is necessary to start daemons (such as dbus, pulseaudio, etc) necessary for linux desktop to work. This is the option kubernetes runs with by default, so most kubernetes based JupyterHubs will not need any modifications for this to work.

Configuration

The VNC server will default to launching ~/.vnc/xstartup. If this file does not exist jupyter-remote-desktop-proxy will use a bundled xstartup file that launches dbus-launch xfce4-session. You can specify a custom script by setting the environment variable JUPYTER_REMOTE_DESKTOP_PROXY_XSTARTUP.

Limitations

1. Desktop applications that require access to OpenGL are currently unsupported.
