Auto-start VNC

This script ensures that whenever a Jetson Orin Nano boots, it automatically brings up:

• x11vnc (to mirror the desktop session :0)
• noVNC (to expose that session over HTTP so we can connect in a browser)

It waits for network connectivity and Xorg display readiness before launching, to avoid race conditions during boot.

Location

• Script file: /home/arc/bin/wait_net_start_vnc.sh
• Logs: /home/arc/.local/state/vnc/
• User context: Runs as arc (hardcoded inside script)

How to Run (Manual)

/home/arc/bin/wait_net_start_vnc.sh

Check logs:

tail -n 50 /home/arc/.local/state/vnc/*.log

Auto-start on Boot (Crontab Method)

We currently rely on cron to launch this script at startup.

1. Edit crontab as arc:

   crontab -e

2. Add:

   @reboot /home/arc/bin/wait_net_start_vnc.sh >>/home/arc/.local/state/vnc/boot.log 2>&1 &

3. Reboot and confirm:

   ps aux | grep -E 'x11vnc|novnc_proxy'
   ss -lntp | egrep '(:5900|:6081)'

Notes

• Auto-login: Ensure /etc/gdm3/custom.conf has:

  [daemon]
  AutomaticLoginEnable=true
  AutomaticLogin=arc
  WaylandEnable=false

Troubleshooting

• Boot log: /home/arc/.local/state/vnc/boot.log
• x11vnc log: /home/arc/.local/state/vnc/x11vnc.log
• noVNC log: /home/arc/.local/state/vnc/novnc.log

Check running processes:

ps aux | grep -E 'x11vnc|novnc_proxy'

Check listening ports:

ss -lntp | egrep '(:5900|:6081)'
