[gentoo-user] Can not start compiz-fusion

[Dan Johansson]

I had some time on my hands and decided to try compiz-fusion.
When I try to start compiz-manager I get the following:

$ compiz-manager
Checking for Xgl: not present.
Detected PCI ID for VGA: 01:00.0 0300: 10de:0422 (rev a1) (prog-if 00 [VGA 
controller])
05:00.0 0300: 10de:0422 (rev a1) (prog-if 00 [VGA controller])
Checking for texture_from_pixmap: present.
Checking for non power of two support: present.
Checking for Composite extension: not present.
aborting and using fallback: /usr/bin/metacity
no /usr/bin/metacity found, exiting

The "Xgl: not present" is because I'm running Xorg (x11-base/xorg-x11-7.2)
The thing that really strikes me is "Checking for Composite extension: not 
present.". What I can see I have Composite enabled:

$ grep -i Composite /var/log/Xorg.0.log
(**) Extension "Composite" is enabled
(**) NVIDIA(0): Option "AllowGLXWithComposite" "true"
(II) NVIDIA(0): Support for GLX with the Damage and Composite X extensions is
(**) NVIDIA(1): Option "AllowGLXWithComposite" "true"
(II) Initializing built-in extension COMPOSITE


And this is a part of xorg.conf:
------------8<----------------
Section "Extensions"
        Option "Composite" "Enable"
EndSection
------------8<----------------

I have two nVidia GeForce 8400 GS Cards installed in this box:
# lspci | grep VGA
01:00.0 VGA compatible controller: nVidia Corporation G86 [GeForce 8400 GS] 
(rev a1)
05:00.0 VGA compatible controller: nVidia Corporation G86 [GeForce 8400 GS] 
(rev a1)

Any suggestions on how to solve this?
