It's a bit unfortunate that we have vino, which by default doesn't
work, in the default installation and its functionality is exposed in
Control Center. I wonder if it'd make a sense to patch the sharing
module in the control center to check if the session is running on
Wayland and if so, to disable the dialog.
My understanding is that screen sharing is moving to the compositor
Pinos  and vino will be deprecated, but in the meantime we
expose its functionality on Wayland.
Thanks for bringing that up.
Yes, Jonas has in the past worked on prototyping screensharing in the
compositor, using pinos. We will have to complete this work and land
it. In the meantime, vino should of course not crash, but exit cleanly
if X is not available.
