I'm experiencing a problem with SDDM where I have two session types available: Plasma (Wayland) and Niri, but when I try to log into Plasma, I'm greeted with a black screen. If I switch back to Niri, everything works fine, but I notice that sometimes both sessions end up on the screen, with Niri taking over the window management and shortcuts. I'm unsure if this is a misconfiguration related to virtual terminals in Wayland. Any advice on how to troubleshoot this?

Also, just a thought—if the problem persists, you could consider creating a separate user account to see if the issue is specific to your current user setup. If the other account works fine with Plasma, it might be something within your current user's settings causing the conflict.
Have you checked if SDDM is configured to use a Wayland compositor like kwin? It often defaults to X11, and that can definitely lead to some glitches. If you have set it to use Wayland and it's still not working, you might want to check the system logs for any errors during the login process. That could give you some insight into what's going wrong.
