Plasma freezes after login

Running Fedora 37/KDE, latest update (5.27.6-2).

When I log in to my regular user account, I see the plasma startup screen and the rotating gear on a black screen. After several seconds (longer than usual), a cursor is displayed and the gear stops rotating, but the screen remains blank and is unresponsive. All I can do is power off. When I log into a bare-bones account, after about 2 seconds the black screen is replaced by the wallpaper and everything looks OK.

I have journalctl logs from the failing login and successful login, but I can’t see any errors or tell what the differences are. Are plasma errors logged somewhere else?

I had this problem last week and recreated my login account from scratch and configured it as I had before, with virtual windows, display setting, etc. I was able to log into the newly created account without problem. It appears that I made some additional configuration change which has triggered this behavior, but I don’t know what it might be.

Any suggestions? Is there a place where I can upload the journalctl logs?

Sounds like the [ScreenMapping] bug. (Don’t remember, this could be fixed already).
Check your ~/.config/plasma-org.kde.plasma.desktop-appletsrc for a huge [ScreenMapping] section, or maybe rename the file and try to login.

To upload journald logs you can use a pastebin service like or

€: X11 or Wayland?

X11. [ScreenMapping] has only one line. – Failing login – Successful login

Will try renaming plasma-org.kde.plasma.desktop-appletsrc.

Renaming plasma-org.kde.plasma.desktop-appletsrc didn’t have any effect.
