HOWTO make emacs truely fullscreen on start-up?

Question

I want emacs to be truly maximized on start up.

There are solutions to the problem - that just make emacs window screen-wide. That's not enough for me. I want emacs window do docked to the right upper corner of the screen - so that when I press there with a mouse - I will close emacs, not firefox or krusader - or what ever - which was maximized in the background.

I thried to do it with kwin - but no luck.

P.S. I'm using Kubuntu, end emacs is quite fresh one 23.2 or smth like that.

Answer 1

I've taken this from somewhere on emacswiki, some time ago. Note that I no longer use it, as I've switched to dwm to have everything fullscreen, but it used to work.

(defun fullscreen ()
       (interactive)
       (x-send-client-message nil 0 nil "_NET_WM_STATE" 32
                 '(2 "_NET_WM_STATE_FULLSCREEN" 0)))

If you want it to run on startup, you should be able to add

(fullscreen)

to your .emacs

EDIT: Rereading your question, I think this is not what you want. This will go really fullscreen, not maximized: you will not have any close button.

This one should do:

(defun fullscreen (&optional f)
  (interactive)
  (x-send-client-message nil 0 nil "_NET_WM_STATE" 32
             '(2 "_NET_WM_STATE_MAXIMIZED_VERT" 0))
  (x-send-client-message nil 0 nil "_NET_WM_STATE" 32
             '(2 "_NET_WM_STATE_MAXIMIZED_HORZ" 0)))

Now it's directly from http://www.emacswiki.org/emacs/FullScreen

I think emacs will respect gconf settings, so you could set /apps/emacs/maximize, but don't know if that will help on Kubuntu -- worth a try.

Answer 3

If you would like to toggle fullscreen in emacs with the F11 key, add the following to .emacs:

;; the following should give fullscreen mode when F11 is depressed
(defun fullscreen ()
 (interactive)
 (set-frame-parameter nil 'fullscreen
              (if (frame-parameter nil 'fullscreen) nil 'fullboth))

If you want the fullscreen emacs to be very minimal (no tool bar, scroll bar, or menu bar, also add:

(progn
  (if (fboundp 'tool-bar-mode) (tool-bar-mode -1))  ;; no toolbar
  (menu-bar-mode -1) ;;no menubar
  (scroll-bar-mode -1) ;; no scroll bar
  )
)

Here are two non-lisp ways to achieve the same:

1) Alias your emacs command to 'emacs -fs'. Add this line of code to your .bashrc file in your home directory: alias emacs='emacs -fs'

Personally, I don't like this approach because I wouldn't want emacs to startup in full screen all the time and would like some control.

2) My solution; In Ubuntu, you can assign a keyboard shortcut to 'full-screen' any window. This seems to be the most convenient and simple option. Besides, it has the advantage that the same shortcut also applies to all your applications.

I use the following on Linux:

(defun my-frame-toggle ()
    "Maximize/Restore Emacs frame using 'wmctrl'."
    (interactive)
    (shell-command "wmctrl -r :ACTIVE: -btoggle,maximized_vert,maximized_horz"))

and then bind it to a key:

(global-set-key [(control f4)] 'my-frame-toggle)

If you want to start out maximized, you can just add a call to my-frame-toggle to the end of your .emacs file.

I found a funny solution:

emacs -nw

starts emacs in a console - and you can maximize console itself!

Answer 7

I found that it's known and long standing bug of emacs (vim sufferst the same).
