Enable Remote desktop feature during build

We can't enable that feature until after pipewire is packaged and promoted to main.

Pipewire is packaged now, can we get it enabled?

Not sure, but it looks like the issue in comment #1 is solved:

https://launchpad.net/ubuntu/+source/pipewire

With that being true, we just need mutter built with the correct flag

Please use --enable-remote-desktop during build, see https://wiki.gnome.org/Projects/Mutter/RemoteDesktop

No, pipewire is not in main. That link in comment #3 shows it is in Universe.

(Additionally, the version is not new enough for mutter 3.36; we need Pipewire 0.3 for that.)

Link in comment #3 also shows an upstream pipewire master

https://launchpad.net/~jan-koester/+archive/ubuntu/pipewiremaster

Maybe we could get that linked as the upstream?

Prerequisites: bug 1802533, bug 1802614

This is still an issue on Ubuntu 20.10, while the GNOME Shell remote-desktop / screencast support on Wayland has been enabled for Fedora and other distributions for some time now.

What is Ubuntu holding back from enabling Wayland remote-desktop support (and consecutively a Wayland-by-default session)?

This bug was fixed in the package mutter - 3.38.3-2ubuntu1

Even with that version of mutter installed I still don't see screen sharing as an option under sharing in the settings app when logged in under Wayland. Are there other packages that need to be updated before screen sharing will be available in Wayland sessions, and are there open bug tickets for those?

@jik, I think that you need the package gnome-remote-desktop, this has a MIR request in bug 1802614. And then another package will need to recommend it to have it installed by default, you can follow this on the Trello board here https://trello.com/c/NnUq5bHv/15-mir-gnome-remote-desktop-and-seed-recommend-it
