Hi,

I don't think you will need anything extra in Xwayland to support this.

What you do need though is the Wayland compositor to support it. The
compositor needs to know to launch more Xwayland servers, and the XWM
(proxying X11 window manager) embedded in the compositor needs to be
able to deal with it too.

So, this question is specific to the compositor you choose to run. I
suspect no current compositor implementation supports this by
configuration alone, you'd need to actually implement the feature first.


Thanks,
