Description of problem:
I have two non-admin users on my system. In the SDDM, both users are visible and I can log in as both users. But after I log in as one of the users into Plasma, the following happens:
In Fedora 32, when I opened the application launcher, it showed an option called "Switch User" (or rather, since my localization is German, "Benutzer wechseln"). After updating to Fedora 34, this option is no longer in Kickoff. Also in Fedora 34, in the lock screen, there is no possibility to switch to another user. The only option is to enter the password for the currently logged-in user. (I am not one hundred percent sure that this option existed in Fedora 32, because I never used it.)
Version-Release number of selected component (if applicable):
KDE Frameworks: 5.80.0
Steps to Reproduce:
1. Open Kickoff
2. Optionally, choose option "lock screen" from Kickoff
No option "Switch user" in Kickoff.
No way to switch user in lock screen.
Option "Switch user" should be visible in Kickoff.
There should be some way to switch the user in the lock screen.
I have tried this out both with Plasma on Wayland and with Plasma on X11, with the same result.
Fast user switching has been increasingly broken over the past few
Fedora releases, and during Fedora Linux 34 development, it reached a
point where it caused a nearly un-fixable release blocking bug
(bug #1929643). We have temporarily disabled the feature by default
until upstream has resolved the issue.
If you wish to enable it again (at your own risk!), you may do so by
adding the following to "~/.config/kdeglobals":

Thank you very much for the information. I have successfully used the workaround. (Haven't checked if the bug still happens.)
