GNOME screen sharing completely borked with recent Mantic updates

[Jonathan Kamens]

The most recent Mantic turned off Screen Sharing, which was previously turned on.

When I go to turn it on in the sharing control panel, i see that sharing is completely disabled, i.e., the rocker switch at the top of the window is off, presumably because the only kind of sharing I had enabled was screen sharing, i.e., I didn't have media sharing enabled, so presumably once screen sharing was turned off sharing in general turned off.

So I turn that top rocker switch back on, and now I need to configure screen sharing, which still says it's off, so I click on that.

The window that comes up says VNC, which is *VERY* strange since we quite a while ago switched from VNC to RDP, right? Why has it reverted to VNC?

But in any case I can't do anything at this point. The rocker switch in the upper left corner of the screen sharing pop-up won't let me turn it on. The rocker switch next to my network connection won't let me turn it on. And there's no way to close the pop-up! I have to kill the settings app to make it go away at this point.

This is bad.

This sounds like either a Settings bug, or just a natural consequence of (accidentally?) removing some dependencies from the default install. The latter I think is also the responsibility of the Settings app to resolve or communicate to the user what's missing.

This was a PEBKAC issue. I was opening the Unity sharing control panel instead of the GNOME sharing control panel.

I have no idea why the Unity sharing control panel is still on my computer. I thought unity was gone. ;-)
Is it safe to remove it?
