Image Display

Display recent images from a folder to the screen.

Setup

Install the python requirements: pip install -r requirements.txt.

Run

Start manually:

• nohup python front_end.py &
• Set the display: export DISPLAY=:0
• Show full-screen in Firefox: firefox --kiosk --private-window http://127.0.0.1:123
• Or Chromium: chromium-browser --kiosk http://127.0.0.1:1234

If there is no local archive, it needs to be updated. Run: nohup python update_archive.py &

Or, start with systemd: This will start the program when the computer starts and revive it when it dies. Copy the contents of front_end.service to /etc/systemd/system/front_end.service (via sudo vim /etc/systemd/system/front_end.service).

Start the front-end service using the commands below.

• sudo systemctl daemon-reload
• Start it on boot: sudo systemctl enable front_end.service
• Start it right now: sudo systemctl start front_end.service
• Stop it right now: sudo systemctl stop front_end.service
• Get logs: sudo journalctl -u front_end | tail

Move the contents of update_archive.service to /etc/systemd/system/update_archive.service: sudo vim /etc/systemd/system/update_archive.service:

• sudo systemctl daemon-reload
• Start it on boot: sudo systemctl enable update_archive.service
• Start it right now: sudo systemctl start update_archive.service
• Stop it right now: sudo systemctl stop update_archive.service
• Get logs: sudo journalctl -u update_archive | tail

TODO: this should be run as a standalone file: file://display.html in the browser! TODO: browser should open on startup! /usr/bin/chromium-browser --kiosk http://127.0.0.1:1234
