streamdeck-gui-ng - Next Generation Linux compatible UI for the Elgato Stream Deck.

Why This Fork?

I use Stream Deck every day and depend on it for my workflow. When I noticed that streamdeck-linux-gui had entered maintenance mode and was no longer accepting new features, I decided to fork it to ensure continued development and modernization.

This fork aims to:

• Modernize the codebase with support for current Python versions (3.11+)
• Fix security vulnerabilities and keep dependencies up to date
• Continue active development and feature improvements
• Maintain compatibility with the latest Stream Deck devices

Project History

streamdeck-gui-ng is the third generation of this project:

1. streamdeck_ui (Original) - Created by Timothy Crosley, this was the first Linux UI for Stream Deck. The project was abandoned when the original author disappeared.

2. streamdeck-linux-gui (First Fork) - The community forked the original project to keep it alive. However, this fork eventually entered maintenance mode in 2024, accepting only critical bug fixes while directing users to StreamController for new features.

3. streamdeck-gui-ng (This Fork) - A modernized continuation for users who prefer the original architecture and want continued development of this proven codebase.

All credit to the original authors and the many contributors to both previous projects. This fork builds on their excellent work.

Key Features

• Linux Compatible: Enables usage of Stream Deck devices (Original, MK2, Mini and XL) on Linux.
• Multi-device: Enables connecting and configuring multiple Stream Decks on one computer.
• Brightness Control: Supports controlling the brightness from both the configuration UI and buttons on the device itself.
• Configurable Button Display: Icons + Text, Icon Only, and Text Only configurable per button on the Stream Deck.
• Multi-Action Support: Run commands, write text and press hotkey combinations at the press of a single button on your Stream Deck.
• Button Pages: streamdeck_ui supports multiple pages of buttons and dynamically setting up buttons to switch between those pages.
• Auto Reconnect: Automatically and gracefully reconnects, in the case the device is unplugged and replugged in.
• Import/Export: Supports saving and restoring Stream Deck configuration.
• Drag/Drop: Move buttons by simply drag and drop.
• Drag/Drop Image: Configure a button image by dragging it from your file manager onto the button.
• Auto Dim: Configure the Stream Deck to automatically dim the display after a period of time. A button press wakes it up again.
• Animated icons: Use an animated gif to liven things up a bit.
• Runs under systemd: Run automatically in the background as a systemd --user service.
• Stream Deck Pedal: Supports actions when pressing pedals.
• Plugin System: Extend functionality with Python plugins that can monitor external services, update buttons dynamically, and respond to events. See Plugin Development Guide.

Documentation

Communication with the Stream Deck is powered by the Python Elgato Stream Deck Library.

Documentation is available at [https://millaguie.github.io/streamdeck-gui-ng/](https://millaguie.github.io/streamdeck-gui-ng/)

Installation Guides

• Arch/Manjaro
• CentOS
• Fedora
• NixOS
• openSUSE
• Ubuntu/Mint

Once you're up and running, consider installing a systemd service.

Use the troubleshooting guide or search the issues for guidance. If you cannot find on the issue on this repository please try searching on the original at streamdeck_ui.

Precooked Scripts

There are scripts for setting up streamdeck_ui on Debian/Ubuntu and Fedora.

Plugin System

StreamDeck UI now supports a powerful plugin system that allows you to extend functionality with custom Python scripts. Plugins can:

• Monitor external services (APIs, databases, servers, etc.)
• Update button appearance dynamically based on real-time data
• Respond to button presses with custom logic
• Request page switches when important events occur
• Run continuously or only when visible

Example Plugins

The repository includes two production-ready example plugins:

Prometheus AlertManager Monitor (plugins/alertmanager/):

• Monitors AlertManager for active alerts
• Updates button display with alert count
• Changes color based on severity
• Flashes and switches pages on new alerts
• Opens AlertManager in browser when pressed
• Supports multiple authentication methods

Arch Linux Update Monitor (plugins/arch_update/):

• Monitors system updates (pacman, AUR, Flatpak)
• Shows update count with color coding
• Displays breakdown by source (P:pacman, A:AUR, F:Flatpak)
• Launches update command in terminal on button press
• Supports any AUR helper and terminal emulator
• Automatic page switching on new updates

See the Plugin Development Guide for complete documentation on creating your own plugins.

Quick Start

1. Create plugin directory: ~/.streamdeck_ui/plugins/my_plugin/
2. Add manifest.yaml with plugin metadata
3. Write your plugin extending BasePlugin
4. Restart StreamDeck UI
5. Assign plugin to a button in the UI

Updating Documentation

Documentation is powered by mkdocs-material, and its on the docs folder. Install it with pip install mkdocs-material and run mkdocs serve to see the changes locally, before submitting a PR.

Known issues

• pip package is not yet available for the current state of the project. Please install from source, currently trying to find a better way to provide the package.
• Streamdeck uses pynput for simulating Key Presses but it lacks proper support for Wayland. Generally your results will be good when using X (Ubuntu/Linux Mint). This thread may be useful.
• Key Press or Write Text does not work on Fedora (outside of the streamdeck itself), which is not particularly useful. However, still do a lot with the Command feature.
• Some users have reported that the Stream Deck device does not work on all on specific USB ports, as it draws quite a bit of power and/or has strict bandwidth requirements. Try a different port.
• If you are executing a shell script from the Command feature - remember to add the shebang at the top of your file, for the language in question. #!/bin/bash or #!/usr/bin/python3 etc. The streamdeck may appear to lock up if you don't under some distros.
