Not all emacsclient processes have a=20 corresponding display, e.g. if you just do emacsclient --eval '(+ 1 1)' there is no display involved. If you create an emacsclient process with=20 -c or -r, then in Elisp you can get the display on which the frame is=20 displayed with (getenv "DISPLAY"), or (cdr (assq 'display=20 (frame-parameters))). --wyi6EhAydt--
