I followed this page (Ubuntu, how to display server windows on Windows 10 client hosts with Putty and XMing Server) trying to make some changes in the Xavier NX display so I can use xming to show Xavier NX GUI on a windows system with Putty. I could not make it work. So I would like to go back to Xavier NX original display manager. After select the display manager “gdm3” and reboot, I found my desktop is different from the original Xavier NX desktop. Please see the attached. How can I change the display manager to the orginal one?
