How to use Emacs in full screen mode ?
Full screen on X11
The following maps the function 11 key to toggle fullscreen on X11 (Linux, BSD, etc…).
Add this in your .emacs :
(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))))
(global-set-key [f11] 'toggle-fullscreen)
However, I tested it on Emacs23 and it does not replace my window correctly if it was maximised, so I prefer the following method :
Using external program
Install wmctrl (sudo apt-get install wmctrl). Add the following in your .emacs :
(defun switch-full-screen ()
(interactive)
(shell-command "wmctrl -r :ACTIVE: -btoggle,fullscreen"))
(global-set-key [f11] 'switch-full-screen)
And now you can write in piece.
