Debug: Service Deactivated After Installing Dependencies

What Happened

The service:

  1. Started successfully
  2. Installed dependencies
  3. Deactivated successfully (exited cleanly)

This means it finished running but didn't actually launch the Flask app.

Most Likely Cause

web_display_autostart is probably set to false in your config.json

The service is designed to exit gracefully if this is false - it won't even try to start Flask.

Commands to Run RIGHT NOW

1. Check the full logs to see what it said before exiting:

sudo journalctl -u ledmatrix-web -n 200 --no-pager | grep -A 5 -B 5 "web_display_autostart\|Configuration\|Launching\|will not"

This will show you if it said something like:

  • "Configuration 'web_display_autostart' is false or not set. Web interface will not be started."

2. Check your config.json:

cat ~/LEDMatrix/config/config.json | grep web_display_autostart

3. If it's false or missing, set it to true:

nano ~/LEDMatrix/config/config.json

Find the line with web_display_autostart and change it to:

"web_display_autostart": true,

If the line doesn't exist, add it near the top of the file (after the opening {):

{
  "web_display_autostart": true,
  ... rest of config ...
}

4. After fixing the config, restart the service:

sudo systemctl restart ledmatrix-web

5. Watch it start up:

sudo journalctl -u ledmatrix-web -f

You should see:

  • "Configuration 'web_display_autostart' is true. Starting web interface..."
  • "Dependencies installed successfully"
  • "Launching web interface v3: ..."
  • Flask starting up

Alternative: View ALL Recent Logs

To see everything that happened:

sudo journalctl -u ledmatrix-web --since "5 minutes ago" --no-pager

This will show you the complete log including what happened after dependency installation.
