Manual foreground start in debug mode:

emacs -u user -chdir /home/user --fg-daemon=emacs.user --debug-init
Loading t-mouse...
Loading t-mouse...done
Error setting gpm-mouse-mode: (error Gpm-mouse only works in the GNU/Linux console)
Starting Emacs daemon.
(What I expect from gpm-mouse-mode is to have a clickable bar menu)

--------------------------------------------------------------------------
Meanwhile lauching a standalone emacs for the same account and ini file
the bar menu is clickable

Sorry for this long post, hoping it doesn't sound too silly.
Comment 1 Ulrich Müller gentoo-dev 2019-02-14 17:54:42 UTC
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. So it might be best if you report the issue upstream.
Comment 2 CaptainBlood 2019-02-26 00:57:48 UTC
I send a bug upstream, mentionning this bug thread url.
I'm not sure they read it.

Their current proposal is to use:

(add-hook 'after-make-frame-functions

which I did the best I could, but it gave identical result.

In the mean time I wondered one thing as here rc-update resturns:

            emacs.user |      default                           
           emacs.root |      default                           

II can't retrieve where I got this setting from, but could changing default to boot make any difference?
Comment 3 CaptainBlood 2019-02-26 01:20:52 UTC
moreover, emacsclient from a xorg terminal .emacs requires:

;; the two lines seems required from a xterminal.
(custom-set-variables
'(gpm-mouse-mode t)
'(xterm-mouse-mode t))

Please note behavior isn't the same as standalone emacs, as it open a help buffer, but at least mouse intercation is there!
Comment 4 Ulrich Müller gentoo-dev 2024-02-21 13:14:20 UTC
Is this still a problem in Emacs 29.2?
