Meanwhile also verified on ctwm with 4 screens.

Although confirmed as working stable multiple times,
unfortunately, Elv13 stated that nobody @ Awesome would care about
independent X11 screens ("ZaphoMode") any more;
c.f. https://github.com/awesomeWM/awesome/issues/598#issuecomment-305114301 ff.

Same disinterest stated by leading upstream (=KDE) developers.

If really nobody cares besides me,
I do not mind to close as "WONTFIX".

Manfred can you please confirm if this issue still occurs with AwesomeWM or CTWM. I don't have machines with either of these to test, thanks.

Burying my father took precedence.

Multiple separate X11 screens setup (Zaphod, no Xinerama),
although being a perfect liable X11 option,
has been ignored and explicitly labeled as "irrelevant"
by the two main KDE developers and others.

Thus I finally gave up on KDE and dbus broken by design.

is dating back to 2015 and before.

Reported errors have been verified even on ctwm (!) with 4 screens.

After all these years of ignorance,
NEEDSINFO sounds quite bitter in my ears.

The named setup is not available any more.

RESOLVED as WONTFIX would be much more honest, at least.

Hello Manfred. KDE Developers, as other opensource developers have one thing in common: they are people with limited time, that in majority do not get paid to work on opensource, and also that prefer to fix something that they can easily reproduce.
It also means that we fix things that we are affected, and that sometimes a software will lack a maintainer (or the desire to work of a maintainer will lower).
Konsole has had more commits in the past 2 years than in the combined 10 years past - that shows that konsole is good and striving. Who are those developers? Users of konsole that started to fix bugs for them, and submiting upstream, like myself.

"Thus I finally gave up on KDE and dbus broken by design." - If you have technical level, please don't just report bugs, try to help fixing them.

I don't (won't) install another WM just for testing - I don't get paid to work on konsole and my time is limited, so I work on what I like / want.
Try to get your hands dirty too, helping us to debug what's wrong on VM's - This way it's easier for the developers and users.

Tomaz.
