I cant seem to find any info on it.
My observation is that itās quite similar to SDDM, but currently a little more basic.
But you basically use it the same way - choose what to log in, then enter the password (and choose the environment if you have X11 and Wayland).
You need to install it. plasmalogin .
It will add a new section in System Settings.
Note that SDDM is not removed here, as installing a new login manager, at least on Debian and Ubuntu based systems, doesnāt remove any existing ones. Youāll see a prompt in the terminal to choose which one you want to use when installing it.
Note that this might default to x11 for the desktop session, so look for that when logging in. It did for me, which caused some oddities, like screen layout changes and refresh rate drops as I use two different monitors.
I havenāt used x11 on my main desktop/gaming pc since at least 2022 so it was a momentary annoyance, until I quickly realized what happened.

Heheh, mine defaulted to a Kodi session. Seems to work OK. Thanks. It appears to default to screen two upon booting. Any idea how to turn off the secondary display upon bootup and force it back to the primary like it was for SDDM?
Mine was never like that for SDDM ootb, though on my only dual screen setup, I usually do autologin at the moment. I set it up for single-screen ages ago, so it may have changed.
I think the old ātrickā is still valid: temporarily disable the unwanted monitor , then use the āApply Plasma settingsā option. Or edit a config, but I am away from home so I canāt double check.
I tried adding the xrandr command that previously worked with SDDM in /usr/share/plasmalogn/scripts/xsetup but that did not work.
I am hoping I can get the secondary screen to remain off during the login, but to turn on after login. This was usually accomplished with SDDM by adding
xrandr --output hdmi-0-1 --off
to /usr/share/sddm/scripts/xsetup.
On arch linux, I installed the plasma-login-manager package from the extra repo, then I disabled sddmās service and enabled plasma login managerās service.
I also removed sddm afterwards, but you donāt have to do that.

I will probably remove it as well. I will give it a few days of testing before I do though.
Like I mentioned, temporarily s disable your monitor via the settings, then apply Plasma Settings in the Login Manager settings. Then, re-enable the monitor.
Iām not sure, but the login manager and some SDDM setups now use a Wayland session by default, not x11, so youād probably want to use kscreen-doctor and a different config file.

So for me here in neon, using the "apply plasma settingsā option copies various desktop config files to /var/lib/plasmalogin/.config/.
kwinoutputconfig.json is the one with monitor information.
Ohhhā¦ I get it now. That makes sense actually. I will give it a try. (edit - that worked, thanks!)
After the release of the new KDE Plasma 6.6, I reinstalled Arch Linux from scratch. I found out that KDE now has its own login screen, so I looked into it, disabled SDDM, and everything seemed fine.
However, when SDDM was still enabled, I had to click twice to restart the computer in order for the restart confirmation message to appear. The first time I clicked, the prompt just disappeared. After disabling SDDM and enabling Plasma Login, restarting the system works correctly ā the restart confirmation appears on the first click.
But now the same issue happens when shutting down the computer ā I have to click two or three times before the shutdown confirmation appears. I reinstalled the system two or three times before I realized that the issue was related to the login screen.
To do this, I used the following commands:
sudo systemctl disable sddm
sudo systemctl enable plasmalogin
