Reply To: Screen sharing for Linux users

Well, the most likely cause is that it seems that you use Wayland window manager (I believe it is the default in Gnome now). Unfortunately, currently we support screen sharing on Linux only for traditional X11/Xorg sessions. You should be able to select the type of the session at your Ubuntu login page (you need to select “Ubuntu on Xorg” or something like that to start Xorg session).
