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?
