X DEs don't set the $WAYLAND_DISPLAY environment variable, so querying for it returns an empty string.
If I run this in X:emacsclient --alternate-editor= --display=$WAYLAND_DISPLAY .emacs.el
the following occurs.When the --display argument is an empty string, Emacs first tries to reuse an exiting frame and, if doesn't find one, it falls back to open it in the same terminal. The problem arises when an instance is launched through the DE facilities: Emacs can't use a terminal as a fallback and therefore it opens in the background without showing the frame.
If we decide that handling such case is not worth the trouble, an error in system log should warn the user to use the X backend.
