thank you so much for your help

OK, this theme shouldn't cause the difference in brightness, I think.  I
have another guess.  Does Fedora use "site-start.el"?  If so, this file
is not loaded by Guix's Emacs, because it is placed somewhere in
/usr/share/... and Guix's Emacs doesn't look at this directory (also our
emacs uses its own "site-start.el" to load emacs packages installed in

You can check if Fedora's Emacs uses "site-start.el" with this:

  M-x find-library site-start

Yes, the Fedora Emacs has this site-start

;;; loaded before user's ".emacs" file and default.el

;; load *.el and *.elc in /usr/share/emacs/site-lisp/site-start.d on startup
  (mapcar 'file-name-sans-extension
           "/usr/share/emacs/site-lisp/site-start.d" t "\\.elc?\\'"))))
(setq source-directory "/usr/share/emacs/24.5/")

and the Guix Emacs has

(require 'guix-emacs nil t)


But actually I don't understand how the difference in brightness can
happen at all.  This is a mystery for me.

You can move the point to 'variable-pitch' button and press RET there to
find out if it has the same customization in both cases.

This is the same for both Emacses

Face: variable-pitch (sample) (customize this face)

The basic variable-pitch face.

Defined in `faces.el'.

OK, so Fedora's Emacs has a bigger font (19 against 13).

You can use something like this to set the font and its size:

  (set-frame-font "DejaVu Sans Mono-15" nil t)

you were spot on on this ! In fact evaluating this line made the Guix Emacs window exactly equal to the one of the Fedora Emacs !

This should be fixed if you change the font size.

Right ! Even the minibuffer now is reasonably large and readable !

Another thing: I noticed that Guix's Emacs doesn't display some buttons
on the tool bar.  This should probably (I'm not sure) be fixed by
installing some icon theme in your profile, for example

I installed this adwaita thing but the icons keep not being there

Also the Fedora Emacs keeps being a bit brighter

But that's not that bad ! The showstopper was the tiny tiny minibuffer

And if that's a mistery to you, go figure what it is to me ;-)

Thanks for your help ;-)
