Tested in the following environments
Open.OC2: Jetson Nano Production module, L4T R32.6.1
Host: VNC Viewer 6.21.406 on Windows 10

Reference tutorial: here

  1. You will need to connect to the Jetson module over SSH, it requires to know its IP address (e.g. 192.168.1.15) and your username <<USERNAME>>. In a terminal:
    ssh <<USERNAME>>@192.168.1.15
  2. Use your password to start the session.
  3. Install nano, tigervnc-standalone-server and autocutsel:
    sudo apt install nano tigervnc-standalone-server autocutsel
  4. Set a password for the VNC server:
    vncpasswd
  5. Create the file ~/.vnc/xstartup using nano:
    nano ~/.vnc/xstartup
  6. Edit with the following content: 
    !/bin/sh
export XDG_RUNTIME_DIR=/run/user/1000
export XKL_XMODMAP_DISABLE=1
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
xrdb $HOME/.Xresources
xsetroot -solid grey
# copy/paste enablement
vncconfig -nowin &
autocutsel -forkgnome-session &
startlxde &
  7. Save and exit nano: Ctrl+o (o as in Oscar) to save, press Enter to continue, then Ctrl+x to exit
  8. Make xstartup executable:
    chmod +x ~/.vnc/xstartup
  9. Check if .Xresources exists:
    ls -al ~/.Xresources
  10. If it does not exist, create it:
    touch ~/.Xresources
  11. Open VNC conf file:
    sudo nano /etc/vnc.conf
  12. Check if $localhost = "no"; is NOT commented.
  13. Set up the autologin using GDM3:
    sudo nano /etc/gdm3/custom.conf
  14. Uncomment the following lines (replace <<USERNAME>> by your username): 
    AutomaticLoginEnable=true
AutomaticLogin=<your username>
  15. Save and exit nano: Ctrl+o (o as in Oscar) to save, press Enter to continue, then Ctrl+x to exit
  16. Create a service to make VNC server start automatically:
    sudo nano /etc/systemd/system/vncserver@.service
  17. Add the following content, and replace <<USERNAME>> by your username : 
    [Unit]
Description=Start TigerVNC Server at startup
After=syslog.target network.target

[Service]
Type=forking
User=<<USERNAME>>
Group=<<USERNAME>>
WorkingDirectory=/home/<<USERNAME>>
PIDFile=/home/<<USERNAME>>/.vnc/%H:%i.pid
ExecStartPre=-/usr/bin/vncserver -kill :%i > /dev/null 2>&1
ExecStart=/usr/bin/vncserver :%i -depth 24 -geometry 1920x1080 -nolisten tcp
ExecStop=/usr/bin/vncserver -kill :%i

[Install]
WantedBy=multi-user.target
  18. Save and exit nano: Ctrl+o (o as in Oscar) to save, press Enter to continue, then Ctrl+x to exit
  19. Load the new service:
    sudo systemctl daemon-reload
    sudo systemctl enable vncserver@1
    sudo systemctl start vncserver@1
  20. Service status can be checked using:
    systemctl status vncserver@1
  21. Install VNC viewer on your machine and connect to 192.168.1.15:1. 192.168.1.15 is the IP address and :1 is the VNC server to connect to.
