no 3D works after compiz-manager started

I try to set up the 3D desk after starting compiz-manager. But noting works.

I am using nvidia, it is already eselected by opengl. But just does not work.

It works when I first install this gnome version, but after the new installation, it does not work.

Hope get help, thx


Section "Extensions"
  Option "Composite" "On"

module-rebuild -X rebuild

P.S. I do not have gnome, nvideo, compiz, intuitively trying to help, sorry for english (
