gnome-session depends on xwayland

[Fred]

With GNOME Wayland it should be possible to run GNOME without any legacy X or xwayland support. It should be an optional dependency, not a hard dependency.

If anything, it should be a gnome-session-wayland dependency, not a gnome-session dependency.

Honestly, I don't think there's any intention to not have XWayland installed by default. It could be useful if XWayland is only started when needed, which is what GNOME #759538 is about.

By the way, in Ubuntu 17.04 there is no separate gnome-session-wayland package; it's been merged into gnome-session.

But not everyone have the need to run legacy X11 applications.
Some people are fine with just Wayland and don't need to run legacy applications.

My understanding is that neither Firefox nor Google Chrome/Chromium are native Wayland apps, so unless you're using something like Epiphany for your web browsing, yes you do need XWayland.

@Jeremy Bicha: In the meantime Firefox wayland support has arrived (still not enabled by default. callable with --enable-default-toolkit=cairo-gtk3-wayland) and Chromium wayland ozone builds are quite stable.

I think this is implemented starting in Ubuntu 18.10.
