"echo $XAUTHORITY" prints nothing, and (getenv "XAUTHORITY") returns
nil.

gdm3 is not installed here (this is a Kubuntu system,) and if anyone
thinks on the famous GTK bug that prevents remote Emacs terminals,
please note that this Emacs uses Lucid.

This worked for a long time but it is the first time that I need to use
a remote session since more than a year ago, so it is either something
introduced by an OS upgrade or by Emacs. I'll try to bisect it (which is
pain because IIRC the build method changed on this timeframe plus the
Emacs VC graph used to be a mess.)

Some more random data points:

$ emacs -nw

M-: (make-frame (list '(window-system . X)))
Debug entered-Lisp error: (error "Don't know how to create a frame on
window system X")

M-x abort-recursive-edit

M-: (make-frame (list '(window-system . X) (dispay . ":1124")))
Debug entered-Lisp error: (void-function display)

No need to be sorry. Thanks for trying.
