Can you enlighten me on how to actually use this virtual output, with regards to screen sharing?
I tried Gnome Network Display before, however there is no way to configure it via KDE System Settings (as is not part of KDE). I believed this feature is also not available yet.
Also, I don’t think that having a virtual output created through Screensharing feature is “right”. It should be created through (KDE) System Settings, where it is available afterwards to share via Screenshare Portal.
Also, network display virtual output does not help on the scenario I’m discussing, where there is only one physical screen available.
