I don't know what you're trying to say.

you dont have a seat manager running which is a dependency

It seems that I need to explain that it is currently a container environment, so it needs to share the graphics card with the host computer.
I tried some methods to make it work, but some issues arose, such as only displaying a gray screen after VNC connection, and the following error messages:
00:00:00.059 [seatd/seat.c:281] Could not make device fd drm master: Device or resource busy.
I guess all the problems stem from Hyprland's attempt to monopolize the GPU, rather than just using it as a renderer.

@vaxerski It worked after disabling the main display device eDP-1.
But I don't know why it can only be disabled and mirror cannot be used.
Additionally, manually creating headless output after each startup is quite cumbersome.
