Description slartibart70 2023-01-04 11:17:43 UTC

If i switch from x11 to a wayland session, the logout hangs with a black screen on virtual console 1, just a blinking cursor on screen.
I need to go to e.g. virtual console 3, login as root and do a 'systemctl restart sddm.service' to get a login back.

In x11, no problem with logouts
One thing to mention: in fedora (36,37) when using x11, we have the plasma session on vconsole2, vconsole1 is displaying (old) boot messages. 
But, in wayland, the gui is on vconsole1. vconsole2 displays the last sddm login-screen grayed-out, still showing the background, the password-input field with your input replaced by 'dots'.
A logout shows the blinking cursor on vconsole1, vconsole2 still shows the defunct sddm-login 

Independent of how long you wait, sddm will not recover. You have to kill/restart it using systemctl

This sounds like a SDDM bug. Can you report this issue to SDDM developers and leave a link here?
