Description quininer 2021-11-15 17:51:51 UTC

In x11, we can add virtual display devices through `xrandr`, but in wayland, we need kwin to provide a specific interface.

Gnome and Sway already support this feature, it will be useful if kde can support it.
see https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1698 and https://github.com/swaywm/sway/pull/5216

KWin from git master already supports that through xdg portals

This sounds great, is there a document describing how to create a virtual monitor on git master?
