Ubuntu host no display unless dummy dongle plugged in after client connection

[Divinity9434]

Pretty much as the title states. Here are the details:

Host – Ubuntu headless (amd igpu if that matters)

Client – Windows

I can only get a usable display if I boot up the ubuntu box, then go to the windows client and connect to it, and then plug the dummy dongle in.

If I boot the ubuntu machine with the dongle plugged in, only the top left corner of the display will appear.

Does anybody know what could be causing this?

Ut is up to a system, GPU configuration how it handles headless screen.

To setup NoMachine to work headless you can follow this article. https://kb.nomachine.com/AR04R01083
