I am currently running a Jetson Nano as a server the run the Spaghetti Detective for 3d Printing. I currently do not have the GUI Desktop loading on boot and if needed, just issue the command “$sudo systemctl start gdm3”. If I want to kill the GUI Desktop and go back to the command line prompt, issuing "sudo systemctl stop gdm3" kills the desktop, but the command prompt does not appear. Only a cursor with no command line.
The question I have is if anyone knows how to accomplish this? I do not want to keep the desktop running in the background to free up memory.
