Share GTK application windows within google meet under Wayland

Trying to share a GTK application window with might not work if you run under a Wayland session.

A workaround is to run a GTK application under XWayland:

GDK_BACKEND=x11 gedit

Now gedit can be shared within google meet.

If you want to share a gnome-terminal window, things are a bit more complicated. gnome-terminal has a client/server architecture so gnome-terminal-server needs to run with the x11 backend.

mkdir -p ~/.config/systemd/user/gnome-terminal-server.service.d/
cat <<EOF > ~/.config/systemd/user/gnome-terminal-server.service.d/override.conf
systemctl --user daemon-reload
systemctl --user restart gnome-terminal-server

The last command will kill all your terminals!

Now you can share your gnome-terminal windows again!
