10.04 - Enable compiz on intel core i5 (Nvidia GT330M) based laptop

I am trying to enable compiz on my laptop via Desktop Effects but it does not allow it. I modified the xorg.conf file as on the compiz wiki but still no luck.

So can someone just tell me how to enable compiz desktop on an Intel i5 based system. This is an Arrandale processor so its got the graphics bit on the processor itself. My system also has a discrete graphics card (Nvidia GT330M - yup its those hybrid graphics combos n- not Optimus). As far as i know the nvidia gpu is not being used since the intel one is enabled and there is no bios route to disable it. The laptop is a Dell Vostro 3700 with bios version A10

I did lotsa google searches about intel compiz, etc but not a single conclusive guide as to how to enable it. so my guess is it should work out of the box. but it doesn't.

glxinfo

gives me:

lsbusb gives me:

I managed to get compiz to work. i uninstalled nvidia's proprietary driver (nvidia-current). now with nouveau, glxinfo gives decent output and says direct rendering is enabled (turns out its talking about the intel chip). then i go to desktop effects, and when i select extra, it says install nvidia proprietary drivers, i click cancel, the screen blinks but compiz is now enabled
