Another Workaround:
This is using the Nvidia driver and not nouveau, right? I believe this is a
driver in the Nvidia driver that is not asking for the conflicting framebuffers
to be unregistered.
You can try to add "initcall_blacklist=simpledrm_platform_driver_init" to your
kernel command line

Same problem for me on Ubuntu 24.04 fresh install on X11.
I tried updating my nvidia driver to nvidia-driver-550, but I keep
getting this "phantom" monitor in Gnome settings.
I have two physical monitors :
- Main one : AOC 27" AG271QG with G-Sync
- Other one : Dell 25"
$ find /sys/devices
I upgraded from 23.10 to 24.04 and I have the same issues plus other problems:
+Two monitors designated as Unknown display
+most gnome apps (like Setting, alert message) don't render the characters as
in
Same problem with Nvidia driver 535.171.04 on Ubuntu 24.04
