This also fixes a defect we are seeing in a VMWare guest with Ubuntu 16.10. The issue was wallpaper does not get resized when changing to a higher desktop resolution, leaving a black border around the wallpaper, and corruption occurs when when dragging a window over that black border.

Instead of your wallpaper you see black. [ Fix ] Inside nautilus, the wallpaper widget connects to GTK's "monitors- changed" signal when it is constructed. It does this only once the widget is realized - a "realized" signal handler connects to "monitors-changed". In Yakkety, the "realized" signal handler is connected after the widget is already realized, meaning that the signal handler isn't called and we don't connect to the "monitors- changed" signal. The proposed fix remedies this by checking if we are realized and explicitly calling the signal handler if so. [ QA ] Have multiple monitors. Have only one of them connected. Log in. Plug in one monitor. If it's autoactivated, check you see your background on both monitors. If not, activate it ("Displays") and do the same. [ Regression potential ] I'm not sure why or where the order changed to make the widget be realized earlier, if it matters or if this was always buggy and we got lucky. I would guess a refactoring in Nautilus itself, and so the proposed fix is safe, but watch out for other weirdness.
