Package: emacs
Version: 29.0.90

In previous versions of emacs, if the DISPLAY/WAYLAND_DISPLAY variable
was not set, it would default to tty mode.  In version 29, it seems to
assume a default value and complains that it can't connect to the
display server unless you run it with -nw.

Too bad.  I added some verbiage to this effect in NEWS, and I'm
closing this bug.

(With all these disadvantages, I wonder why the PGTK build was
considered such a useful addition to Emacs...)

Btw, the Emacs user manual says WAYLAND_DISPLAY is the variable used
by PGTK, which you seem to say is inaccurate?
