Everything KDE built from source this morning with Qt 5.15.0 on top of

Kickoff and Kicker are no longer displaying the "Switch User"
functionality. However if I search for "Switch user" in KRunner, it
displays an item called "New Session" which works as expected. It's just
Kickoff and Kicker that don't have the functionality visible anymore.
Not reproducible with Plasma 5.19, just my built-from-source git master
stuff.

So it does still exist, but it's hidden from introspection.
And always returns true anyway: 8f8cc84ba4612e74cd1e26898c6816e6e60fc4e9 which makes our check somewhat redundant!
I'm still confused by the reports in the duplicate saying it doesn't work.
It does here.
Can someone who still has an issue include output of:

Oh, interesting. So we have 3 options:

GetSessionFromPid works in old systemd but broke in newer versions

auto is only available in new systemd
I assumed if auto didn't work I could just leave it on the old path...
seemingly that is not the case.

Maybe the fallback doesn't work as intended?

Thanks!
Super worst case, we can just return /self if /auto fails. It should
work.

You should try with Plasma 5.20.0, for which this bug report was closed as fixed originally.
5.19.5 doesn't have the new code (https://invent.kde.org/plasma/plasma-workspace/commit/3acf8f30249ef256c2a915a12048f55da0568492) yet.
It should be in Tumbleweed soon.

Indeed, on my system (with systemd 234), it doesn't use the fallback with GetSessionByPID.
seat.isValid() is true in line#435, even though "auto" doesn't exist. So it enters the if() and returns true before calling GetSessionByPID.
If I disable that "if(seat.isValid() { return true; }" part (so the fallback is always used), the button is visible on the login screen now and clicking on it does show existing user sessions.
So the fallback code itself (with GetSessionByPID) does work.

I don't have more time for testing or investigating at the moment
though. (and it might be an unrelated problem)

I have switch user function from the application menu which functions to
take you to a new login screen showing list of users, and options;
Switch to This Session, Start New Session, and Back. Choosing the Switch
to This Session option results in session hang on an empty screen with
the wallpaper and mouse pointer (same as described in comment 27). Start
New Session, and Back both work as expected.
I do not have any options on the lock screen to Start New Session or
Switch to This Session.

I completely agree - this should be marked SEVERE! The original bug only
concerned missing functionality on the kicker menu. If limited to that,
this would not prevent users from using the system. That kicker menu
issue has been at least partially fixed.
However the current issue is regarding missing functionality on the
lockscreen! This issue COMPLETELY DISABLES PROPER FUNCTION OF A
MULTIUSER SYSTEM! Users CAN NOT LOGIN! That is not a normal bug
importance! Apologies for CAPS :P
https://bugs.kde.org/show_bug.cgi?id=427673 was imho inappropriately
marked "resolved duplicate" but that bug properly describes the current
issue and its severity "Session management is totally broken - system
does not work with multi-user parallel sessions - Critical."

I think I will try to create a shell script to switch to the correct
user and stick it to the plasma desktop.
The only problem is that logind now keeps some processes alive and the
list of active sessions becomes really long.

@cyslider at posteo.de Indeed you need some extra workarounds. Disable the
Screensavers and use "loginctl disable-linger" on those desktops. It
works better if everything is kept clean. I now added the ".desktop"
file to create a launcher on a desktop.
But this actually needs to get fixed.

Fix SystemEntries not updating correctly
The code is meant to add the entry if it's valid, then watch for
changes. Somehow we end up only monitoring if it was valid initially.
This doesn't make sense.
This means if the menu loads before the backend we don't update
correctly when it does load.

[libkworkspace] Fix if getCurrentSeat needs to fallback to old approach
The test for whether "/auto" is supported was bogus.
QDBusAbstractInterface::isValid effectively just confirms the service
exists and the path is a legally valid name, not that it has any
interfaces there.
This means the fallback path is not run appropriately.

Forgive my ignorance, but will this fix be backported to 5.18.x? Or will the fix only apply to 5.20.3?
Am currently on Kubuntu 20.04 with version 5.18.5.

[lookandfeel] Fix switching to a different user session
Commit bcaf3886 removed the property `m` in UserDelegate.qml, but it is still used by
`userListCurrentModelData` in SessionManagementScreen.qml at least.
This broke switching to an existing session via the "Switch User" button on the lock screen or the
application launcher/menu, it just hung with an empty screen and this runtime error in the logs:
file:///usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/lockscreen/LockScreenUi.qml:444: TypeError: Cannot read property 'vtNumber' of undefined
Adding it back makes switching work again (and gets rid of the runtime error).
FIXED-IN: 5.20.3
