Thanks @dbarronoss
I am not running Plasma so I can mistaken with the login manager.
I see sddm in the inxi that’s why I suggest enable sddm service.
System:
Kernel: 6.19.10-arch1-1-bsb arch: x86_64 bits: 64 compiler: gcc v: 15.2.1
Desktop: KDE Plasma v: 6.6.4 tk: Qt v: N/A wm: kwin_wayland dm: 1: LightDM
note: stopped 2: SDDM Distro: EndeavourOS base: Arch Linux
The main thing is trying disable/remove lightdm as login manager and use the plasma login way.
