Designed primarily for Raspberry Pi kiosks, menu boards, and in-store displays, with **local caching**, **offline resilience**, and **simple lifecycle management**.\n\nGTK Signage is distributed as a **Flatpak application** and managed using straightforward install, update, and uninstall scripts.\n\n---\n\n## Features\n\n* **Web Admin Interface**\n  Add, edit, and delete slides via a browser\n\n* **Flexible Display**\n  Show web pages or uploaded images\n\n* **Scheduling Support**\n  Control slide visibility with start/end timestamps\n\n* **Secure Access**\n  Password-protected admin login with hashed credentials\n\n* **Local Caching**\n  Saves web content (HTML, JS, images, CSS) to survive internet outages\n\n* **Minimal Display Stack**\n  Fullscreen GTK WebView using WebKit (no Chromium)\n\n* **Flatpak Distribution**\n  Self-contained app with predictable dependencies\n\n* **Auto-Start on Login**\n  Uses standard XDG autostart (no systemd or shell hacks)\n\n* **HTTPS Support**\n  Optional self-signed SSL certs for the admin UI\n\n* **HDMI-CEC Support**\n  Optional scheduled and manual display power control on supported hardware\n\n---\n\n## Installation\n\n### Files Required\n\nYou need **two files in the same directory**:\n\n* `install.sh`\n* `GtkSignage.flatpak`\n\nDownload the Flatpak bundle from:\n\n```\nhttps://github.com/mgroves/GtkSignage/releases\n```\n\n---\n\n### Install\n\n```bash\nchmod +x install.sh\n./install.sh\n```\n\nThe installer will:\n\n1. Ensure Flatpak is installed\n2. Prompt for configuration values\n3. Require and confirm an admin password\n4. Write `config.ini` to a Flatpak-visible location\n5. Install the local Flatpak bundle\n6. Configure auto-start on login using XDG autostart\n7. Optionally enable auto-login (highly recommended)\n\n---\n\n## Updating\n\nTo update GTK Signage using a new Flatpak bundle:\n\n```bash\nchmod +x update.sh\n./update.sh\n```\n\nThe update script will:\n\n1. Verify the existing config\n2. Back up `config.ini` with a timestamp\n3. Apply any future config migrations (if present)\n4. Optionally reinstall the Flatpak from a local bundle\n\nConfiguration is preserved.\n\n---\n\n## Uninstalling\n\n```bash\nchmod +x uninstall.sh\n./uninstall.sh\n```\n\nThe uninstall script will:\n\n* Remove the autostart entry\n* Uninstall the Flatpak\n* Optionally remove all GTK Signage config and data\n* Optionally remove auto-login\n\n---\n\n## Configuration\n\nGTK Signage uses a **single INI config file**, written by `install.sh`.\n\nLocation:\n\n```\n~/.var/app/com.mgroves.GtkSignage/config/com.mgroves.GtkSignage/config.ini\n```\n\nYou can find an example in `config.ini.example`\n\n---\n\n## Admin Interface\n\nOnce running, the admin UI is available at:\n\n* HTTP: `http://\u003cdevice-ip\u003e:\u003cport\u003e/admin`\n* HTTPS (if enabled): `https://\u003cdevice-ip\u003e:\u003cport\u003e/admin`\n\nLog in using the credentials provided during installation.\n\n---\n\n## Slide Management\n\n### Slide Properties\n\n* **Source**: URL or uploaded image\n* **Duration**: Display time in seconds\n* **Start Time**: Optional scheduled start\n* **End Time**: Optional scheduled end\n* **Hide**: Temporarily disable without deleting\n\nSlides are stored in `slides.json` under the configured data directory.\n\n---\n\n## Licensing\n\nGTK Signage uses a **dual licensing model**:\n\n* **Free** for small businesses with 1–2 physical locations\n* **Commercial license required** for 3+ locations\n\nSee [LICENSE.md](LICENSE.md) for details.\n\n---\n\n## Support\n\n* **Free support**: GitHub Issues\n  [https://github.com/mgroves/GtkSignage/issues](https://github.com/mgroves/GtkSignage/issues). The CLA is \"whenever I get around to it\".\n\n* **Commercial support**:\n  [info@grovesmanagementllc.com](mailto:info@grovesmanagementllc.com). The CLA is negotiable.\n\n---\n\n## FAQ\n\n**Q: Why not Chromium kiosk mode?**\nA: Chromium is heavy and fragile for long-running signage. GTK WebView + WebKit is simpler and more predictable.\n\n**Q: Why Python?**\nA: GTK bindings made Python the path of least resistance, despite my dislike of Python.\n\n**Q: Is this supported on Windows or macOS?**\nA: No. Linux only, Raspberry Pi only.\n\n**Q: Is there a roadmap?**\nA: Yes. See [ROADMAP.md](ROADMAP.md).\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmgroves%2Fgtksignage","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmgroves%2Fgtksignage","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmgroves%2Fgtksignage/lists"}
