The fix is in plasma-workspace (not kscreenlocker), since 5.20.3. But no, there should be no extra step necessary. If you have plasma-workspace 5.20.4 (or 5.20.3), it should work (you'd have to logout/login or reboot of course after installing the update). It certainly works fine again in the latest openSUSE Tumbleweed (with systemd 246.7 and Plasma 5.20.4 meanwhile), I just tried a LiveCD. -- You are receiving this mail because: You are watching all bug changes.

So my "workaround" in comment#4 would probably be an acceptable fix?
(I'd think falling back to the ConsoleKit code shouldn't be necessary anymore
if we successfully did get a systemd seat already...)

Maybe something like this would be necessary to get the "CanMultiSession"
property as well?
(this is from KDisplayManager::SystemdSeat,
https://invent.kde.org/plasma/plasma-workspace/-/blob/master/libkworkspace/kdisplaymanager.cpp#L150
)
/* HACK to be able to extract a(so) type from QDBus, property doesn't do
the trick */
QList getSessions() {
QDBusMessage message = QDBusMessage::createMethodCall(service(),
path(), DBUS_PROPERTIES_IFACE, DBUS_PROPERTIES_GET);
message << interface() << SYSTEMD_SESSIONS_PROPERTY;
QDBusMessage reply = QDBusConnection::systemBus().call(message);

--- Comment #4 from Wolfgang Bauer ---
I had a look at this on openSUSE Tumbleweed, which also has systemd 246 and
this problem.
The "Switch User" button is indeed missing because
KDisplayManager::isSwitchable() returns false.
For reference, here's the code of KDisplayManager::isSwitchable():
if (DMType == NewGDM || DMType == LightDM) {
QDBusObjectPath currentSeat;
if (getCurrentSeat(nullptr, )) {
SystemdSeat SDseat(currentSeat);
if (SDseat.isValid()) {
QVariant prop = SDseat.property("CanMultiSession");
if (prop.isValid())
return prop.toBool();
}
... (ConsoleKit stuff follows here)
Now the problem is that with systemd 246, SDseat.property("CanMultiSession")
yields QVariant(Invalid), i.e. apparently getting that property fails.
Although, "qdbus-qt5 --system org.freedesktop.login1
/org/freedesktop/login1/seat/auto org.freedesktop.DBus.Properties.Get
org.freedesktop.login1.Seat CanMultiSession" does work and returns true.
But the property is not listed in qdbusviewer either.
As a quick test, I changed the code to this:
if (prop.isValid())
return prop.toBool();
else
return true; // if the property cannot be get, assume that
MultiSession is supported
Now the button appears again, and user switching works (together with
https://invent.kde.org/plasma/plasma-workspace/-/commit/c5fa3a15a444b0e7c9113b2dd0351e1cf7141d29,
otherwise switching to an existing session just hangs on an empty screen ).
