Bug 464846

Hi,

when having a multi-monitor setup, sddm shows the initial login screen on both windows, and when I start typing only one of the textfields gets populated. After hitting ENTER, the password typed into the textbox selected is used. So if I type my password into one textfield, select the other one and press ENTER my password is rejected.

Real world use-case:
- system boots with multi-monitor, sddm focuses one of the textboxes, let's say on screen A.
- I type my password into the already focused textbox.
- Than I reach for the mouse and shake it to find the cursor.
- If I shake it too much, it gets to the other screen, onto screen B.
- I change between X11 and Wayland (typically from X11 to Wayland) on the drop-down menu of screen B as it is closer to my cursor.
- Now my cursor is closer to the textbox of screen B, so I click on it and press ENTER.
- My login attempt fails.

I see multiple solutions:
1) to synchronize all the textboxes on all the screen, so when typing into one, the others gets populated with the same text. This way, it doesn't matter where I want to login.
2)  When trying to login, check all the typed textbox password for login. This may ease brute-force attempts but I'm not sure if that is an actual problem.

Thanks if you look into it!
Best regards,
Gergely
