Package: mutter
Version: 2.28.1~git20091208-1
Severity: normal
The opacity of the emacs23 editor does not work with mutter.
Preparation:
* Insert into .emacs for Emacs 23:
(defun djcb-opacity-modify (&optional dec)
"modify the transparency of the emacs frame; if DEC is t,
decrease the transparency, otherwise increase it in 10%-steps"
(let* ((alpha-or-nil (frame-parameter nil 'alpha)) ; nil before setting
(oldalpha (if alpha-or-nil alpha-or-nil 100))
(newalpha (if dec (- oldalpha 5) (+ oldalpha 5))))
(when (and (>= newalpha frame-alpha-lower-limit) (<= newalpha 100))
(modify-frame-parameters nil (list (cons 'alpha newalpha))))))
;; C-8 will increase opacity (== decrease transparency)
;; C-9 will decrease opacity (== increase transparency
;; C-0 will returns the state to normal
(global-set-key (kbd "C-8") '(lambda()(interactive)(djcb-opacity-modify)))
(global-set-key (kbd "C-9") '(lambda()(interactive)(djcb-opacity-modify t)))
(global-set-key (kbd "C-0") '(lambda()(interactive)
(modify-frame-parameters nil `((alpha . 100)))))
* restart emacs.
How to test the problem:
Ctrl-9 should increase editor's transparency
Ctrl-8 should decrease editor's transparency
Ctrl-0 should reset transparency of the editor
Works with metacity and composite manager activated.
No transparency at all with mutter.
