Optimus nvidia graphic driver - Running nvidia only

Hello.
I have an ASUS Model : K95VJ
Bios : American Megatrends Inc. v230 01/24/2013.
Intel HD Graphics 4000 , driver i915
NVIDIA GT 635M , nouveau driver

openSUSE 12.3 (x86_64) (3.7.10-1.16-desktop)
VERSION = 12.3
CODENAME = Dartmouth

Before digging into bumblebee for using optimus functionality, is there a way to blacklist i915 and use only the nvidia card.
