I recently switched from Xorg to Wayland and I'm quite happy with my new
setup! The only last "little" thing that doesn't work for me is
screen-sharing using Icecat and/or Chromium!? :-(
And, I won't go back to Xorg "just" for that! ^_^'

I would be grateful if someone could tell me how to set up the
PipeWire thingy!?

I've installed `pipewire`, `xdg-desktop-portal-wlr`, and `wireplumber`…
set up the ENV variables `WAYLAND_DISPLAY` and `XDG_CURRENT_DESKTOP`…
set the proper flag in Chromium… but it doesn't seem to work!?

I thought it would be dbus "auto-magic", but apparently not. Event if I
manually start `pipewire` and `wireplumber`, nothing happens when I try
to share my screen, for instance while in a Jitsi Meet meeting.

Any advice welcome! … even a good old RTFM, if it comes with a link to
get the information from! :-)

Regards,
