Description James Bates 2021-01-01 20:20:46 UTC
Since remote-desktop-desktop (the Wayland screen sharing option) does not (yet) work in Gentoo, vino is (currently) the only option to share a screen in Gentoo+gnome. In contrast to the statement here:, vino does NOT actually work, even in an xorg session, when net-misc/vino is explicitly merged.

The reason is that upstream has indiscriminately disabled vino:

It is relatively straightforward to undo this commit, at least until the wayland option works. Ubuntu have already done it:

The patch in question, which I have attached to this issue, works fine in Gentoo: after applying it, the "Screen Sharing" option in the Gnome settings is once again available and functional, just as it was in all previous versions of Gnome.

Reproducible: Always

Steps to Reproduce:
1. install gnome-base/gnome-settings-daemon-3.36.1
2. install net-misc/vino-3.22.0-r3
3. start an Xorg (not a Wayland) gnome session (e.g. by selecting "GNOME Xorg") among  the available sessions in gdm, or by merging with USE="-wayland")
Actual Results:  
In the gnome settings app, Sharing tab, "Screen Sharing" will appear, but will be inoperable (the activation toggle is inactive). 

Expected Results:  
In the gnome settings app, Sharing tab, "Screen Sharing" should appear, AND be activatable, as it always was in previous gnome versions.

oh, I knew 3.36.5 did that in gnome-control-center with this NEWS item:

- Replace vino with gnome-remote-desktop for X11 sessions.

But apparently you found something that did it earlier at gnome-settings-daemon level then.

I think at this point the solution from my POV is to just move to gnome-remote-desktop and figure out the remaining things for that to become the default for us. As in, if I have time to work on this topic, that's the route I would take. That said, maybe someone else on the team can put that in meanwhile, and perhaps bump gnome-control-center to 3.36.5 while reverting that ones vino removal for the time being (because it also contains an important runtime fix for application panel some of our users are suffering).
