SUMMARY

During the login prompt with the default theme, booting the system while a second screen is plugged in will load a bugged version of the SDDM, with greyed out icons and if an attempt to log in is made, the password box greys out, and the system will be locked unless the SDDM is restarted from the VT, and the only fix is to restart the system/SDDM with the second screen is disconnected

STEPS TO REPRODUCE
1. Restart system while a second screen is plugged in
2. Attempt to log in
3. Get locked out

OBSERVED RESULT
SDDM hangs, only way forwards is to restart it or the system

EXPECTED RESULT
SDDM passes through the login process and greets us to the desktop

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: KDE neon 6.2
KDE Plasma Version: 6.2.2

ADDITIONAL INFORMATION

Performed on a Acer Nitro 5 Laptop with NVIDIA GPU
