We don’t use vncserver, however did check out the website and it appears that you need a paid license to use it.

#6

Thanks @foxsquirrel. You can install without paying and it’s legal.
Perhaps I need to look for alternatives.

#7

Installed following jetson nano. link to jetson nano vnc setup

Ubuntu version installed : vim3-ubuntu-20.04-gnome-linux-5.18 ( I think version is not important)

ONLY WORKS IF A SCREEN IS CONNECTED TO BOARD

  • Install vino ( images does’nt have vino installed )

    $ sudo apt-get install vino

    You can share screen on settings

  • Enable VNCserver

    $ mkdir -p ~/.config/autostart
$ cp /usr/share/applications/vino-server.desktop ~/.config/autostart/.

  • Configure the VNCserver

    $ gsettings set org.gnome.Vino prompt-enabled false
$ gsettings set org.gnome.Vino require-encryption false

  • Replace thepassword with your desired password

    $ gsettings set org.gnome.Vino authentication-methods "['vnc']"
$ gsettings set org.gnome.Vino vnc-password $(echo -n 'thepassword'|base64)

  • Reboot

    $ sudo reboot

Then, you need to install vncclient on your computer to control khadas remotly
