No mutter decorations

I am trying to run mutter under xfce, problem is there is no decorations.
I installed gconf-editor, gnome-tweak-tool and gnome-control-center but
I see no options regarding the decorations.
I haven’t check gnome-themes.
Any hint is appreciated.

This is on openSUSE 12.2

What do you mean by “no decorations”? If application windows don’t have a title bar, then the window manager has crashed (mutter or another one). You should have a look in your .xsession-errors to find the cause.

Why do you want to run mutter under xfce? You don’t have to answer, but it sounds like a weird idea. (?)

Here is the error

Window manager warning: Log level 16: The program 'mutter' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
  (Details: serial 623 error_code 8 request_code 7 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

I usually use kwin and it always work flawless in xfce but curious about mutter so I tried it.

Thanks for your reply

To add on my first post.
I think normally, when window decoration fails to load, you will not be able to move the window with mouse.
In this case even with out the decoration I can still move the window using the mouse.
