Plasma6 upgrade - Startup and Shutdown Behavior missing from system settings

[bearymore]

I n the recent upgrade to Plasma6 I seem to have lost the ability to set system behavior on startup and shutdown. There was a “Startup and Shutdown” section in system settings which had a “Behavior” button at the bottom which took you to a screen which allowed you to set autologin, shell and graphics options and seemed to be a frontend for SDDM. It’s gone or relocated in Plasma6 or at least I can’t find it. Does anyone have any clue?

Yep, a couple threads away from this one:

Plasma 6 Upgrade - NetworkManager frontend missing

After the Plasma 6 upgrade, I seem to have lost the NetworkManager KDE applet. This formerly resided on my taskbar and has disappeared both from there and the application menu. I have different network configurations that I use from time to time and the ability to switch easily is why I use NM. Another minor issue: What happened to the screen in System Settings that allows you to set whether or not to autologin after logging out from Plasma?

SDDM Theme broken after update to Plasma 6 with no way to change it back?

I worked around this issue by rolling back, changing the theme and then updating again. Now DPI Scaling is broken but that’s unrelated. The issue is because the kcm_sddm package isn’t updated to plasma 6 so it isn’t compatible. I have made a bug report so it should get fixed eventually.
