Hi all, thanks to some reddit threads I have this working in GNOME w/Wayland.
- Edit ~/.config/zoomus.conf, set enableWaylandShare=true
- Install xdg-desktop-portal, xdg-desktop-portal-gnome and xdg-desktop-portal-gtk packages
- Restart
I think that’s it? I tried quite a few things but that seems to be all I needed to get screen sharing working on the Zoom app installed via AUR.
