With the standard j4t image that should be installed to the jetson nano (in this case the 4GB dev edition) the desktop is not rendered correctly. The UI shows artifacts and does not function like expected. For example the Terminal would not start at all.

The official tutorials for VNC setup do not provide a solution that works smoothly, so that one can start the Nano in headless mode (without HDMI device conncted). You can connect via VNC but an HDMI device has to be connected, so that the desktop loads correctly. Also with headless mode, I was not able to start any applications like terminal or a browser.

So what can we do to connect with VNC and receive pictures / a video stream that is in a higher resolution format and also where the UI does not show artifacts?

There is also a discussion on the official forums on this topic.

For the following version:

uname -a

Linux jetson 4.9.253-tegra #1 SMP PREEMPT Wed Apr 20 14:25:12 PDT 2022 aarch64 aarch64 aarch64 GNU/Linux

... this is what helped me:

  • connect to the Jetson Nano via SSH

  • install vncserver as well as viewer: sudo apt install tightvncserver && sudo apt install xtightvncviewer then run cmd vncserver and set a password

  • also via SSH, edit the xstartup file:

sudo nano ~/.vnc/xstartup
  • Add these 3 lines and save:
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
startlxde &
  • reboot the Jetson Nano and connect via SSH again, then start vncserver:
vncserver
  • Finally connect to the mentioned display device, e.g. <hostname>:1. Connect via e.g. xtightvncviewer.
