Comments/Problems:

I did two new installations of debian 12 on two different laptops(listed above), this
problem i have on both on them.
If i start my machine i get the normal login screen of sddm on tty7.
Then i can login and the kde loading screen start and after that i have a normal kde
session.
But if i then change witch strg alt f2(for example) the virtual console and back to tty7 i am
logged out of my active kde session and get a sddm login screen with a "pre-typed greyed"
password.Its the same image just before the KDE loading screen appears after you type
your pw and hit enter like on a normal login.

I can only move my mouse around and pressing any key does nothing,no interaction with
the login screen is possible, but i can still switch tty back to like tty2.

If i choose in the sddm login Plasma (X11) this Problem does not appear but if
i change it to Plasma (Wayland) the problem is just a described.
