Someone suggested I get NoMachine to remote into a Jetson Orin Nano. I watched the video at https://www.youtube.com/watch?v=OYrSADrtSag and followed the directions. It seems to follow the same info in the link you had provided.
I also installed NoMachine on a Windows 10 box (and port forwarded the Jetson on the router). But, I must have done something wrong as I cannot remote into the Jetson (with Ubuntu 22.04).
I should NOT have done the headless option until I successfully tested the Windows remote capability. Kind of a bone-headed thing to do, but now I can’t get into the Jetson to run “sudo systemctl set-default graphical.target” to get GUI back.
If I can get the Windows to remote in, that would be ideal, but I’m pretty stymied.
