That `raise-frame' didn't work was a life-and-death problem for
me.  For instance, I couldn't make the Emacs frame (which was
existing but was lowered behind the other frames) pop to the
front using `C-x 5 b'.

Now I realized I can use the program called `wmctrl'[1] to solve
the problem.  Here's an new advice:

(defadvice raise-frame (after make-it-work (&optional frame) activate)
  "Make it work."
  (call-process
   "wmctrl" nil nil nil "-i" "-R"
   (frame-parameter (or frame (selected-frame)) 'outer-window-id)))

It's enough for me, though `wmctrl' does the overkill; `raise-frame'
doesn't always put the input focus on the frame as far as I know,
but `wmctrl' behaves like `select-frame-set-input-focus'.  Anyway,
it suggests that the function that `wmctrl' provides can be
incorporated into Emacs, doesn't it?  I would very much appreciate
someone achieving it.  I have only the knowledge that Fedora Core 4
uses the metacity window manager, sorry.

Indeed `raise-frame' does not work for me in Metacity 2.10.0 (under
Ubuntu).

Hi again,

I recalled this bug has not been solved yet.

I'm now in Fedora 7 that I update everyday.  It runs the metacity
window manager and the problem seems to happen only with LUCID
(not GTK) Emacs on it.  The concrete way to reproduce this bug is:

1. Start Emacs with the -Q option.
2. Type `C-x 5 b *Messages* RET'.
   Now there are two Emacs frames as follows:
+-------------+
|             |
|     +--------------+
|     |              |
|  *sc|              |
+-----|              |
      |  *Messages*  |
      +--------------+
3. Select the *scratch* frame by the mouse.
+-------------+
|             |
|             |------+
|             |      |
|  *scratch*  |      |
+-------------+      |
      |  *Messages*  |
      +--------------+
4. Type `C-x 5 b *Messages* RET' in the *scratch* frame.
   But the *Messages* frame is neither raised nor focused.

The problem I brought up then seems to have been solved now.
However, it seems to be likely different from this.  The whole
thread that contain this article is:

Metacity ignores most focus and raise requests.  It does honor
_NET_ACTIVE_WINDOW.  However, Emacs only does _NET_ACTIVE_WINDOW for
x-focus-frame, not raise-frame.  Why Gtk+ differs I don't know.  Probably it
sets some property behind the scenes that Xt does not.
