SUMMARY My laptop is connected to an external monitor, which is designated as the primary screen. The login prompt appears on both screens (which seem to be mirrored), but the input that has focus is on the laptop screen, which is secondary. Would it be possible to know the primary screen at that stage, or is that information available only after login? PS: apologies if this is the wrong component. The description also says "Don't use this for reporting bugs about locking the screen or logging out.", but it would be more helpful if it said where to file.
yes, I also have a similar problem. My secondary monitor is rotated and the login screen is therefore not really usable on it. I think the login should happen at the primary monitor (if thats possible) or at least what Dan Dascalescu wrote that it gets mirrored on both screen. I hate to say it but Windows does that pretty nicely, where the login screen only appears on the primary screen...
Created attachment 153079 [details] Here is what the login looks like on my screen setup with the primary screen being the big screen on the right

This should be implemented here: https://invent.kde.org/plasma/kscreenlocker/-/blob/master/greeter/greeterapp.cpp?ref_type=heads#L651 But it seems to have been broken for quite a while.

Copied from bug #492502: SUMMARY It would be nice if there was (at least) an option to mirror the password field on the screen saver / screen lock across all screens, such that when I type it in, it will be shown on all screens. This would solve my problem where with multiple screens, when waking up the screens, the first time I enter the password unlocking will fail. STEPS TO REPRODUCE 1. Allow screen to go to sleep 2. Shake mouse 3. Wait until first screen wakes up and presents the password prompt 4. Start typing the password 5. The 2nd screen will be turned on a second (or so) later 6. Now the 2nd half of the password will be entered on the 2nd screen's password prompt input field 7. When you press enter to unlock the computer, the password will be rejected (part of it was entered into one input field and part of it into the other) OBSERVED RESULT Unlock gets rejected. EXPECTED RESULT Password gets input into the password field on all screens and unlock succeeds.
