Package: sddm Version: 0.19.0-5 On one of the machines upgraded from Debian11 to Debian12 I had configured that it automatically logs in. But it seems like in the dropdown next to "with session" after the upgrade this was changed to "Kodi" instead of "Plasma (X11)" (there was no noticeable difference to the standard X11 session and Kodi didn't autostart). It's probably because "Kodi" is the first value in the dropdown which seems to be sorted alphabetically.
Please either make it so that the value before the upgrade is set there or that it's Wayland in specific.
