org.kde.plasma.userswitcher no more switches users

userswitcher works somewhat. But it does not switch users anymore. Any idea?

https://bugs.kde.org/show_bug.cgi?id=424322 possibly? Or related to https://bugs.kde.org/show_bug.cgi?id=423526

I’ve not fully read either of those so don’t know how relevant they may be to your problem.

There seem to be a few “switch user” bugs at present…

Thanks for hinting: https://bugs.kde.org/show_bug.cgi?id=426847

The KDE Bug Reports are referring to logging in as another user – either from a locked session or, presumably, from the KDE Starter …

  • But, the Plasmoid should, theoretically do the same thing …

[HR][/HR]Be that as it may, with AMD Hardware and X11, since SDDM has been deemed to be the Desktop Display Manager flavour of the month, I have been experiencing the issues described in the KDE Bug Reports …

  • With Leap 15.2, I’ve narrowed it down to “sets of sessions with one Akonadi user logged in” …
  • If there ain’t a user with Akonadi active in the set then, everything switches back and forth like a dream – no lock-ups …
  • To date, what I haven’t tried is, within the set of “no Akonadi” users start Firefox and begin to stream whatever from the Internet …

I’m beginning to suspect that, the (maybe too) Simple «overly simplified» DDM isn’t handling active network data streams related to the users in the set of logged in users, properly …

Some freezing occurred with amdgpu, but went away with keeping Tumbleweed up to date. The user switching issue started after upgrading the following packages to 20200917:
