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

/etc/X11/xorg.conf

Section "Extensions"
  Option "Composite" "On"
EndSection

?!

Thx, it works!

After assembling the core modules should compile a package associated with the kernel (such as nvidia-driver, madwifi-ng, etc.). To do this, run:

module-rebuild -X rebuild

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