From their repo:
Plasma Login
Plasma Login provides a display manager for KDE Plasma, forked from SDDM and with an new frontend providing a greeter, wallpaper plugin integration and System Settings module (KCM).
What we want
- Great out-of-box experience in multi-monitor and high DPI and HDR
- Keyboard layout switching
- Virtual keyboards
- Easy Chinese/Japanese/Korean/Vietnamese (CJK) input
- Screen readers for blind people (which then means volume control)
- Remote (VNC/RDP) support from startup
- Deeper Plasma integration including:
- Display and keyboard brightness control
- Full power management
- Pairing trusted bluetooth devices
- Login to known Wi-Fi for remote LDAP
I guess that person didn’t know they could set it up themselves. Maybe they meant that it’s installed and configured automatically on new installs.
Due to how atomic works on bazzite the update for it will preconfigure it to work
they would still be totally wrong. it will be available for new installs the moment kde adds it to the plasma packages. their comment makes zero sense.
