[1]: Workaround to bug: maximize* commands don't work for Emacs -
https://savannah.nongnu.org/bugs/index.php?63979

There are a few ways to achieve this on Linux. The Emacs wiki has a some
examples, e.g:

(defun toggle-fullscreen ()
  "Toggle full screen on X11"
  (interactive)
  (when (eq window-system 'x)
    (set-frame-parameter
     nil 'fullscreen
     (when (not (frame-parameter nil 'fullscreen)) 'fullboth))))

Or:
(defun switch-full-screen ()
       (interactive)
       (shell-command "wmctrl -r :ACTIVE: -btoggle,fullscreen"))

The first example also could work with PGTK, but the example only checks for
window system of x build .

Thank you, but none of the solutions worked in Trisquel 11 (X11).

 I'm not sure how exactly fullscreen should be
done on Wayland.

Is the builtin function `toggle-frame-fullscreen` enough?

That will open emacs in full screen mode, as the subject says I want it to maximize. However, as a side note, I observed that toggle-frame-fullscreen expands the buffer quickly (like `emacs --maximize`) which gives me hope.
