SUMMARY
The "Automatically log in as user" option under "Behaviour" remains greyed out if /etc/sddm.conf.d/kde_settings.conf is edited directly before it is first used graphically. Also, changing it graphically later messes with the theme settings.

STEPS TO REPRODUCE
1. Change kde_settings.conf without opening systemsettings, such as:
     [Autologin]
     Session=plasmawayland
     User=mainuser
     [Theme]
     Current=breeze
2. Open "Behaviour" in kcm_sddm and observe the displayed autologin settings.
3. Change the settings graphically.
4. Observe the changes in kde_settings.conf.

OBSERVED RESULT
After 1 & 2, the autologin settings remain greyed out and incorrect.
After 3 & 4, the autologin settings start working normally, regardless of where they are changed (file or dialog).
After 3 & 4, the theme setting is unset.
