Trouble with ppa:ubuntu-desktop/gnome-3-26

@Igor I’ve run some tests, and it looks like things are running smoothly so far.

I do have some questions, and I’m hoping you can talk through some of your changes in more detail. A number of plugs are no longer there when I thought they were required. For example, I noticed you removed several plugs from the storage-explorer app. We have a native module that explicitly uses X11, and I think Electron’s Chromium uses Wayland for some things. My guess is some of your additions are more comprehensive?
