Hi!

I installed KDE Plasma with SDDM and Xorg to my computer.
The problem is that when I boot up my PC, I get multiple, overlapping login screens.

My computer has a touchpad with a display function. This small login screen is probably what should be displayed there.
I want to disable the touchpad display function and the little login screen.

My computer's OS is Arch Linux.
To be honest, I don't know if this problem is caused by KDE Plasma.

Thanks!

P.S.
English is not my native language.

I solved this problem.
I tried this: https://blog.victormendonca.com/2018/06/29/how-to-fix-sddm-on-multiple-screens/

SDDM caused it.
I'm sorry for the trouble I've caused you.
