Remote desktop

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.
