Get gdk_display_get_primary_monitor

[Alexis BRENON @Xfce]

I don't know much about GTK3 lib, but is a default screen always defined? I
know that on Arch, with Xfce I can set up a dual monitor setup without
defining any "Primary screen". I don't know if both (default monitor and
primary screen) are linked.

Alexis.
