Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

After the customizing of mouse face, the face of mouse is saved as following
in .emacs file.

'(mouse ((t (:background "purple" :foreground "black" :box (:line-width 2 :color "black" :style released-button) :underline "black")))))

But the background options is not effective when emacs is started again. Backgroun is always "white".

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/share/emacs/23.1/etc/DEBUG for instructions.

I could not reproduce a problem with Debian's 23.2+1-7. As a guess,
perhaps some window manager / desktop environment theme is imposing
itself.

Again. It is found that mouse-color is defined in default-frame-alist as following.
(setq default-frame-alist
      (append (list '(foreground-color . "black")
            '(mouse-color . "white")
            '(cursor-color . "black")
            '(width . 120)
            '(height . 50)
       default-frame-alist))
The above 'mouse-color' was effective although the following were defined in parallel.
'(mouse ((t (:background "blue" :foreground "black" :box (:line-width 2 :color "black" :style released-button) :underline "black")))))
The problem was not there in former version of Emacs such as 21.3.1.

Hm, I tried reproducing this now in Emacs 27, but then I realised I
didn't know what to look for.  What is the `mouse' face used for?  It
can't be the mouse pointer, I guess, and it's not used for
highlighting.  I tried grepping, but the only usage I could find was in
speedbar.el.

Anybody?

The 'mouse' face's background color is the color of the mouse pointer.
See the description of 'mouse-color' frame parameter in the node "Font
and Color Parameters" in the ELisp manual.

I see; thanks.  But if I change that face, I can't see anything changing
with the mouse pointer.  Does it depend on, er, what graphics library
and OS you're using?

Yes, I think it's only visible in non-toolkit builds or something.

I tried a -with-x-toolkit=no, which gave me

  What window system should Emacs use?                    x11
  What toolkit should Emacs use?                          none

and still no difference that I can see with the mouse pointer.

Neither does

(setq default-frame-alist
      (append (list '(foreground-color . "red")
		    '(mouse-color . "white")
		    '(cursor-color . "blue")
		    '(width . 120)
		    '(height . 50))
	      default-frame-alist))

affect the mouse pointer here...

Does it work to invoke Emacs with --mouse-color=white?

No, the mouse pointer remains stubbornly black with a white outline.  I
wonder whether perhaps Gnome (or something) is overriding the mouse
pointer.

Could be, I know almost nothing about this X stuff.

Can you at least see in GDB that x_set_mouse_color is called and does
its job of loading the requested color, when you either invoke Emacs
with --mouse-color=white or invoke the set-mouse-color function from
within a running session?

Yup; it's called (and I can see that the colour it tries to set changes
if I vary --mouse-color), but there's no effect on this Gnome-ish
laptop.  I haven't tried in other environments.

OK, thanks.  Maybe someone could try this in other environments, and
we could then update the documentation with the appropriate caveats.
