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`=E2= =80=A6 set up the ENV variables `WAYLAND_DISPLAY` and `XDG_CURRENT_DESKTOP`=E2=80= =A6 set the proper flag in Chromium=E2=80=A6 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! =E2=80=A6 even a good old RTFM, if it comes with a link= to get the information from! :-) Regards, --=20 Tanguy
