I've played with this a bit years ago, bump for now while I try to remember. It's all Xorg stuff so if you're on Wayland I can't help you.

section 3.3 VNC should work for you
what is a dummy video display?
Machine thinks there's a display but there isn't. Useful for servers where you don't really need a screen and you can just remote into the system for maintenance. Some applications don't work unless they detect a screen.
an easy work around would be just pluggin in a display

that's all fine until you're messing with a server located hundred of miles away
cant you use the serial console?
if you need to set up an application that requires a display but you are hundreds of miles away from the machine you need a way to set up a virtual display using software only.
Pretty easy oneliner OP with X. Can't remember it right now but I found it on a thread for adjusting the fans on an nvidia gpu on a headless server. Should be easy to google. nvidia-settings needs a primary display (not really I figured a workaround) so you set up a dummy X display.
i think it was X: 0&. But I'll need to check my bash scripts to confirm.
Ooh, and I think there was something about setting up the DISPLAY env variable. Make sure echo $DISPLAY returns 0 (or 1 can't remember).
nvm fixed it
you need to configure an x11 virtual display, put something in /etc/X11/xorg.conf.d, should appear as VIRTUALn in xrandr.
Also yes, nvidia is fucked and may or may not work with it.
you're looking for xvfb
you just need 3 (three) resistors to short the RGB pins to their returns to make a card believe it's talking to a monitor.
this is the same kind of retard that tells you to import a java library for a simple problem instead of writing a solution yourself
