Please reboot after upgrading to SDDM 0.20 (Snapshot 20230630+)

Hi, in SDDM 0.20, the protocol between the greeter and the daemon changed a bit, which means the greeter from 0.20 will not start properly if the daemon from 0.19 is still running. It's not possible to restart the daemon automatically during/after the upgrade, as this would stop all sessions. The result is that directly after upgrading to sddm 0.20, performing a logout will end up in a black screen. So instead of logging out, just select reboot or shut down directly. If you by accident end up at the black screen, press Ctrl-Alt-F1 to switch to a console and press Ctrl-Alt-Del to trigger a reboot. Or log in as root and run "rcxdm restart; exit" to restart the daemon. Cheers, Fabian
