bug#34648: 26.1; emacs-client: gpm-mouse rejected at daemon launch

I've just tried in .emacs:
(add-hook 'after-make-frame-functions
      (lambda (frame)
        (when (display-graphic-p frame)
          (gpm-mouse-mode t))))
Which does nothing. Switching from when to unless trigger the initial error message.

@ https://bugs.gentoo.org/677826 Gentoo's support noticed: 
The error message is output in function gpm-mouse-start in term.c:

DEFUN ("gpm-mouse-start", Fgpm_mouse_start, Sgpm_mouse_start,
       0, 0, 0,
       doc: /* Open a connection to Gpm.
Gpm-mouse can only be activated for one tty at a time.  */)
  (void)
{
  struct frame *f = SELECTED_FRAME ();
  struct tty_display_info *tty
    = ((f)->output_method == output_termcap
       ? (f)->terminal->display_info.tty : NULL);
  Gpm_Connect connection;

  if (!tty)
    error ("Gpm-mouse only works in the GNU/Linux console");

Debugging with gdb shows that when connected with emacsclient, (f)->output_method is output_initial, while with a standalone Emacs it is output_termcap.
Not sure if the conditional should be changed (to test for output_termcap or output_initial), or if the value of (f)->output_method is wrong.

Did you try to set gpm-mouse-mode from after-make-frame-functions

hook?
