I have two keyboard layouts (gb, fr) as my laptop keyboard is British English and external is French. I added "fr" through system settings > keyboard > layouts > add. If I set the layout to "fr" during a session using the system tray layout icon, and then either logout or reboot, the layout is switched back to "gb" on the login screen, then revert back to "fr" after login in.

This issue does not happen on the lock screen (the layout remains to what it is set during the session.

The expected behaviour is that the last layout used is conserve on the login screen, even after reboot or log out.

It feels like this is to do with the fact keyboard layout are session specific with some kind of default layout being set. It would be good for sddm to be able to somehow access users keyboard settings when a specific user is selected on the login screen.

Sorry if this isn't filed in the right place, I could not see a specific SDDM section. Feel free to move it :)
