Solution to a proposed FAQ, how to maximize emacs quickly (like `emacs --maximize`) for GNU/Linux

Methods to always maximize `emacs` (for example, from Alt+F2 in MATE), 
without the slightly distracting visual effect when the default frame 
size is growing to fullscreen. The window will be maximized quickly, 
like "emacs --maximize".

Windows - Solved

A while ago I suggested how to expand the Emacs window rapidly for 
Windows - 
https://lists.gnu.org/archive/html/emacs-devel/2023-04/msg00155.html

It has now been added:

"

Alternatively, you can avoid the visual effect of Emacs changing its 
frame size entirely in your init file (i.e., without using the 
Registry), like this:

(setq frame-resize-pixelwise t)
(set-frame-position nil 0 0)
(set-frame-size nil (display-pixel-width) (display-pixel-height) t)

GNU/Linux - proposed new section: 
https://www.gnu.org/software/emacs/manual/html_node/efaq/Fullscreen-mode-on-GNU-Linux.html


As far as I know, this cannot be done entirely with Emacs LISP for 
GNU/Linux, but I found a workaround by combining it with devilspie2.


I've successfully used this recipe for Trisquel 11:

* Step 1 to quickly maximize the window[1]: Install, configure, and 
autostart devilspie2 to nearly maximize emacs[1]. Run this in a terminal 
or as a script:

# Install devilspie2
sudo apt-get -y install devilspie2

# Configure devilspie2
mkdir -p ~/.config/devilspie2/

width="$(xrandr --current | grep '*' | uniq | awk '{print $1}' | cut -d 
'x' -f1)"
height="$(xrandr --current | grep '*' | uniq | awk '{print $1}' | cut -d 
'x' -f2)"

tee ~/.config/devilspie2/emacs.lua /dev/null << EOF
if (get_class_instance_name() == "emacs") then

     set_window_geometry(0, 0, $width, $height);

end
EOF

# Autostart devilspie2
mkdir -p "$HOME/.config/autostart/" # The directory does not exist by 
default
cd "$HOME/.config/autostart/" || exit
file="devilspie-2.desktop"
touch "$file"
desktop-file-edit \
--set-name="Devilspie 2" \
--set-comment="Perform scripted actions on windows as they are created" \
--set-key="Type" --set-value="Application" \
--set-key="Exec" --set-value="devilspie2" \
--set-key="X-MATE-Autostart-Delay" --set-value="0" \
"$file"
desktop-file-validate "$file"

* Step 2 to quickly maximize the window[1]: Add this to ~/.emacs: 
(add-to-list 'default-frame-alist '(fullscreen . maximized))
* Log out and then log back into your desktop environment
* Every time you open `emacs`, regardless how you are opening it, it 
will open the window equally fast as `emacs --maximize`

The above steps can of course be rewritten and described for general use 
to make it useful for any GNU/Linux distro.

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

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

Indeed, here are some more fun things you can do with
wmctrl(1)

  https://dataswamp.org/~incal/conf/.zsh/wm
  https://dataswamp.org/~incal/conf/.zsh/transparency

Those files are zsh but the commands works more broadly
than that.

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

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.

Now it sounds like Trisquel is some version of X, but it's
a Linux distro, a distro based on Ubuntu which in turn is
based on Debian.

So wmctrl(1) should absolutely work for that, if you don't
want fullscreen but instead maximizing there are the
maximized_vert and maximized_horz properties - see man man
page for wmctrl, line 39.

To always set, use 'add' instead of 'toggle'. To always unset,
use 'remove'.

Thank you, this is exactly what I want! It expands the window quickly 
(like emacs -mm) from the terminal.


* This works from the terminal with an open emacs Window: $ wmctrl -i -r 
"0x06400142" -b toggle,maximized_vert,maximized_horz


* However *shell-command "wmctrl...* doesn't not run from ~/.emacs 
(tried it in a fresh Trisquel 11 installation from a virtual machine), 
the window size is opened in the default size:

---

Failed the settings suggested by Björn Bidar (as I mentioned earlier):

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

---


Failed with the command that is working from the terminal (escaped double quotes, and made sure that the window is open and that the window ID is correct):

(defun switch-full-screen ()
        (interactive)
        (shell-command "wmctrl -i -r \"0x06400142\" -b toggle,maximized_vert,maximized_horz"))

---


Failed:

(defun switch-full-screen ()
        (interactive)
        (shell-command "wmctrl -r :ACTIVE: -b toggle,maximized_horz,maximized_vert"))


---

Any idea why*shell-command*  is not executed?

It also fails in Ubuntu MATE 23.04 (default window size):

-------------------------8<-----------------------------

sudo apt install -y emacs wmctrl # Just press Enter during the "Postfix 
Configuration"


tee ~/.emacs > /dev/null << 'EOF'

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

EOF


emacs

Yes, do that and then M-x switch-full-screen RET

or just type

  (shell-command "wmctrl -r :ACTIVE: -b toggle,fullscreen")

and do C-x C-e for `eval-last-sexp'.

It doesn't work?

Sorry, it works, I just expected the snippet from Emacs wiki to work 
out-of-the-box automatically. But I had to add: (add-hook 
'after-init-hook 'switch-full-screen)  . Also, "toggle" is useless for 
wmctrl in this situation, so I replaced it with "add", and I replaced 
"fullscreen" with "maximized_horz,maximized_vert"

Here's the final solution for X11 (Trisquel, Ubuntu MATE), but not for 
Wayland (Ubuntu):

(defun switch-full-screen ()
        (interactive)
        (shell-command "wmctrl -r :ACTIVE: -b add,maximized_horz,maximized_vert"))


This is a very compact and useful solution. Again, I suggest it to be documented in the Emacs Manual in a new page:https://www.gnu.org/software/emacs/manual/html_node/efaq/Fullscreen-mode-on-GNU-Linux.html

Again, the devilspie2 solution is much longer, can be used for both X11 and Wayland.

Sorry, I forgot to add (add-hook 'after-init-hook 'switch-full-screen). 
Here's everything:


(defun switch-full-screen ()
        (interactive)
        (shell-command "wmctrl -r :ACTIVE: -b add,maximized_horz,maximized_vert"))
(add-hook 'after-init-hook 'switch-full-screen)

Sorry, I just found out that even if it's added to the top of ~/.emacs, 
this will not expand the buffer quickly like `emacs -mm` for a typical 
~/.emacs that need to load a lot of stuff. It will not expand the buffer 
faster than

     (add-to-list 'default-frame-alist '(fullscreen . maximized)) -- so 
it's a useless solution since it requires wmctrl

Also, the wmctrl solution requires the package to be installed


Right now the only way to automaticall and always quickly expand the 
buffer like `emacs -mm`, regardless the size of ~/.emacs, is to use 
devilspie2 solution that I added in the first post in this thread.

Apologies for joining late, and perhaps you have already tried and
discounted this approach, but: Have you tried adding:

(push '(fullscreen . maximized) default-frame-alist)


or perhaps

(push '(fullscreen . maximized) initial-frame-alist)


to early-init? I put the first above line in ~/.emacs.d/early-init.el, and
got an initially maximized window under an odd Wayland+XWayland system as
well as Win 11. I don't have reasonable access to either a more typical
X11, Wayland, or macOS system right now.

The key is to put it in early-init.el, which is consulted before emacs
makes any windows in any window system. Also worth noting: if you end up
with conflicting elisp settings and X resources, there are a variety of
ways for the latter to silently override the former. You can check this
with "xrdb -query" (you might want to run this in a shell buffer or pipe it
to a pager).

Hope this helps,
~Chad

Today is a good day. This is working like a charm! I tried 
default-frame-alist, and initial-frame-alist, in upgraded virtual 
machines right now:

* X11:

** Trisquel 11: Working

** Ubuntu MATE 22.04: Working

** Ubuntu 23.04: Working

* Wayland

** Ubuntu 22.04: Working

** Ubuntu 23.04: Working

This is the only solution so far that relies 100% on Emacs Lisp. I think 
this can be documented in 
https://www.gnu.org/software/emacs/manual/html_node/efaq/Fullscreen-mode-on-GNU-Linux.htm 


Your solution effectively replaces my devilspie2 solution, Chad. Thank 
you very, very much!


REQUEST: Can anyone please try Chad's solution and confirm if it is 
working for

* Windows 11

* macOS

* BSD


If it is working for all of them, perhaps it's better to add a basic 
section (e.g. 
https://www.gnu.org/software/emacs/manual/html_node/efaq/Fullscreen-mode.htm) 
and document that the solution:

* Will quickly maximize emacs (like `emacs -mm`) by using 
~/.emacs.d/early-init.el, to avoid the slightly distracting visual 
effect of Emacs starting with its default frame size and then growing to 
fullscreen. Adding  "(add-to-list 'default-frame-alist '(fullscreen . 
maximized))" to the top of ~/.emacs will is cause the distracting visual 
effect if additionally typically configurations are added in ~/.emacs.

* Only requires Emacs lisp and works out of the box.

* Will be executed automatically when emacs starts.

* ~/.emacs.d/early-init.el prevents the the visually distracting effect 
is (add-to-list 'default-frame-alist '(fullscreen . maximized))

* Works for GNU/Linux (X11, Wayland), [Windows], [macOS], [BSD]

It works in Windows 11 too. I just tested this in 
Win11_22H2_EnglishInternational_x64v2.iso Home edition, upgraded.

"(push '(fullscreen . maximized) default-frame-alist)" is added to 
.emacs.d/early-init.el it expanded the buffer equally quickly like when 
this was added to a .emacs file (with 100 lines):

(add-hook 'emacs-startup-hook 'toggle-frame-maximized)

(setq frame-resize-pixelwise t)
(set-frame-position nil 0 0)
(set-frame-size nil (display-pixel-width) (display-pixel-height) t)


For GNU/Linux adding this to .emacs (same file size as for the Windows 
11 experiment) caused a delay:

(add-hook 'emacs-startup-hook 'toggle-frame-maximized)


So for Windows, there are two methods that can be used, but for 
GNU/Linux only one solution works (adding "(push '(fullscreen . 
maximized) default-frame-alist)" to .emacs.d/early-init.el)


With this said, the OS independent solution is to add "(push 
'(fullscreen . maximized) default-frame-alist)" to 
.emacs.d/early-init.el which can be documented in a new page, 
https://www.gnu.org/software/emacs/manual/html_node/efaq/Fullscreen-mode.htm

Eli said: "

"Fullscreen" is widely accepted terminology for what is discussed
there.  Moreover, typing "i maximized RET" and "i fullscreen RET" in
both the ELisp and the Emacs user manuals brings you to the same text,
so we already have the two equivalent terms covered, and renaming the
node is not necessary IMO."

EmacsWiki Full Screen, section Configuring fullscreen mode - 
https://www.emacswiki.org/emacs/FullScreen#h5o-2

Probably the simplest way to configure fullscreen or maximized mode is 
to customize |initial-frame-alist|

(custom-set-variables
  '(initial-frame-alist (quote ((fullscreen . maximized)))))

----------------Text that I added 
----------------------8<---------------------

         To avoid the slightly distracting visual effect of Emacs 
starting with its default frame size and then growing to fullscreen, you 
can add an the above lines to .emacs.d/early-init.el instead of .emacs 
(thanks Chad). This has been successfully tested in GNU/Linux (both X11, 
and Wayland), and Windows. -----------------End text that I added

Another option is to not kill Emacs, then you don't have to
start it all the time.

I like Chad's solution to |.emacs.d/early-init.el: |(push '(fullscreen . 
maximized) default-frame-alist)

However, I'd like to compare it with the Lisp code that is executed by 
`emacs --maximize`, can someone please help with find it?

If it's better than Chad's solution, then I'm willing to update "To 
avoid the slightly distracting visual effect" 
(https://www.emacswiki.org/emacs/FullScreen#h5o-3) with code and a 
comment to the source file where this code is found.

Wouldn't it be useful to write some lisp that could automatically 
generate ~/.emacs.d/early-init.el from .emacs?:

* Check if ~/.emacs.d/early-init.el contains:

     (push '(fullscreen . maximized) default-frame-alist)

* If ~/.emacs.d/early-init.el does

   * not exist

   * exist but does not contain the above code

   then:

     * add the above code to ~/.emacs.d/early-init.el

     * restart emacs or send a message to the minibuffer that it must be 
restarted in order for the setting to take effect.

Of course, for the external solution to work you need the
external solution.

A solution that is external but maybe feels more integrated is
to have the window manager maximize the window, should be just
up its alley.

One can also have the window manager execute external
commands for that matter. Here is an example for
openbsd-cwm(1) which I use on Debian

Ubuntu 22.04 (Wayland) cannot use wmctrl like Trisquel 11 (X11) and 
Ubuntu MATE 23.04 (X11) . For Ubuntu, my devilspie2 solution works, I'm 
sure there are other solutions. However, please, let's focus why wmctrl 
cannot be executed from init in Trisquel and Ubuntu MATE right now to 
avoid more confusion.

1. Make the terminal emulator window small so one can see that
   it isn't in fullscreen mode.

2. From the terminal, confirm that this works

   $ wmctrl -r :ACTIVE: -b toggle,fullscreen

3. If it does, in the Emacs window, do the same thing, first
   make it small so it is clear it isn't in fullscreen mode,
   then type and eval with C-x C-e or `eval-last-sexp'

     (shell-command "wmctrl -r :ACTIVE: -b toggle,fullscreen")

It works for me, from the/a terminal as well as from Emacs
with M-x switch-full-screen RET

> Any idea why*shell-command* is not executed?

It is executed, maybe you don't notice the change?

Try removing the maximized_vert and maximized_horz properties,
or set the window size manually to something small, so you can
see that the window isn't in fullscreen. Then just M-x the
fullscreen command as above - should work, right?

Methods to always maximize `emacs` (for example, from Alt+F2 in MATE), 
without the slightly distracting visual effect when the default frame 
size is growing to fullscreen. The window will be maximized quickly, 
like "emacs --maximize".


GNU/Linux - proposed new section: 
https://www.gnu.org/software/emacs/manual/html_node/efaq/Fullscreen-mode-on-GNU-Linux.html


As far as I know, this cannot be done entirely with Emacs LISP for 
GNU/Linux, but I found a workaround by combining it with devilspie2.


I've successfully used this recipe for Trisquel 11:

* Step 1 to quickly maximize the window[1]: Install, configure, and 
autostart devilspie2 to nearly maximize emacs[1]. Run this in a terminal 
or as a script:

# Install devilspie2
sudo apt-get -y install devilspie2

# Configure devilspie2
mkdir -p ~/.config/devilspie2/

width="$(xrandr --current | grep '*' | uniq | awk '{print $1}' | cut -d 
'x' -f1)"
height="$(xrandr --current | grep '*' | uniq | awk '{print $1}' | cut -d 
'x' -f2)"

tee ~/.config/devilspie2/emacs.lua /dev/null << EOF
if (get_class_instance_name() == "emacs") then

     set_window_geometry(0, 0, $width, $height);

end
EOF

# Autostart devilspie2
mkdir -p "$HOME/.config/autostart/" # The directory does not exist by 
default
cd "$HOME/.config/autostart/" || exit
file="devilspie-2.desktop"
touch "$file"
desktop-file-edit \
--set-name="Devilspie 2" \
--set-comment="Perform scripted actions on windows as they are created" \
--set-key="Type" --set-value="Application" \
--set-key="Exec" --set-value="devilspie2" \
--set-key="X-MATE-Autostart-Delay" --set-value="0" \
"$file"
desktop-file-validate "$file"

* Step 2 to quickly maximize the window[1]: Add this to ~/.emacs: 
(add-to-list 'default-frame-alist '(fullscreen . maximized))
* Log out and then log back into your desktop environment
* Every time you open `emacs`, regardless how you are opening it, it 
will open the window equally fast as `emacs --maximize`

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



The above steps can of course be rewritten and described for general use 
to make it useful for any GNU/Linux distro.

AFAIK the HTML pages representing the online Emacs manual are defined
within the sources for the manual, itself.  IOW, to add a "page" for
this would entail creating a new manual section, at which the new page
would appear when new HTML versions of the manual are published, along
with some subsequent release of Emacs (say, the next major version, if
the change was made in the development branch).

This seems like very helpful information.  As a precursor --or even an
alternative-- to proposing a patch to the manual to provide these
examples, what would you think of adding this into the EmacsWiki?   I
believe it is not unheard of to link from the manual to EmacsWiki,
thus you could potentially simplify the patch involved by proposing
adding some minimal explanation and a link (rather than
providing/motivating a patch adding -e.g.- a section).

As far as I know, the devilspie2/.emacs solution that I figured out, is 
the /only/ way to make emacs behave like `emacs -mm` right now. Both of 
them will:

* Always run the settings regardless how emacs is opened (e.g. Alt+F2 in 
MATE) despite that an external program (devilspie2) is used.

* The buffer will:

** Expand automatically when emacs opens

** Expand quickly like `emacs -mm`

* Like `emacs -mm`, the size of ~/.emacs does not impact the time it 
takes to expand the buffer.

This makes the devilspie2 solution unique, since all solutions at 
https://www.emacswiki.org/emacs/FullScreen makes the buffer expand 
slowly. That's why I suggest that we should add my devilspie2/.emacs 
solution to 
https://www.gnu.org/software/emacs/manual/html_node/efaq/Fullscreen-mode-on-GNU-Linux.html

I'm not sure I understand the need for these methods.  Doesn't F11 do
this job on all GUI subsystems we support?

And if you are talking about starting with a maximized frame, then why
aren't "emacs --maximize" and/or X resources (and their Registry
emulation on MS-Windows) good enough?

IOW, before describing your suggested solutions, and for the FAQ on
top of that, could you please describe the problem in more details,
specifically for each GUI environment/toolkit where you see a problem?

Please read the mail in this thread with subject: "Re: Solution to a 
proposed FAQ, how to maximize emacs quickly (like `emacs --maximize`) 
for GNU/Linux - Improved solution by Chad: ~/.emacs.d/early-init.el" to 
understand, so I don't need to re-send it.

I always read everything on this list.  I read those messages as well.
You don't need to repeat them.  But if the suggestions proposed here
didn't solve the problems you had in mind, my question still stands.

      From

      5.48 How can I start Emacs in fullscreen mode on MS-Windows?

Beginning with Emacs 24.4 either run Emacs with the ‘--maximized’ 
command-line option or put the following form in your init file (see How 
do I set up an init file properly? 
<https://www.gnu.org/software/emacs/manual/html_mono/efaq.html#Setting-up-a-customization-file>): 


(add-hook 'emacs-startup-hook 'toggle-frame-maximized)

With older versions use the function |w32-send-sys-command|. For 
example, you can put the following in your init file:

(add-hook 'emacs-startup-hook
           (lambda () (w32-send-sys-command ?\xF030)))

To avoid the slightly distracting visual effect of Emacs starting with 
its default frame size and then growing to fullscreen, you can add an 
‘Emacs.Geometry’ entry to the Windows Registry settings. See X Resources 
<https://www.gnu.org/software/emacs/manual/html_mono/emacs.html#X-Resources> 
in The GNU Emacs Manual. To compute the correct values for width and 
height you use in the Registry settings, first maximize the Emacs frame 
and then evaluate |(frame-height)| and |(frame-width)| with M-:.

Alternatively, you can avoid the visual effect of Emacs changing its 
frame size entirely in your init file (i.e., without using the 
Registry), like this:

(setq frame-resize-pixelwise t)
(set-frame-position nil 0 0)
(set-frame-size nil (display-pixel-width) (display-pixel-height) t)

To avoid the slightly distracting visual effect of Emacs starting with 
its default frame size and then being *maximized*, you can add an add 
this to ~/.emacs.d/early-init.el:

(push '(fullscreen . maximized) default-frame-alist)
