ubuntu22.04 Remote Desktop black screen problem

During the installation of the system, I enabled automatic login and changed the key ring of the remote desktop to an empty password, so as to achieve the purpose of not changing the password at startup. In the remote desktop with windows, I could log in, but the screen was completely black, and the mouse changed to ubuntu style. And in the physical machine directly connected to the display can be controlled by remote desktop, the question comes,How do I stop it from going black.
