I'm having problems trying to use my Nvidia 635M in my asus N46VJ laptop.

I open the "Nvidia X server settings" I get this message :

"You do not appear to be using the NVIDIA X driver. Please edit your X configuration file (just run nvidia-xconfig as root), and restart the X server."

I open the terminal typi "sudo nvidia-xconf" and this creates a file,

/etc/X11/xorg.conf

After reboot I'm in a lower resolution of 640x480, without other options to change it, then open the Details system and it shows me this in the Graphic item:

Intel® Ivybridge Mobile

I type this in the terminal (no idea what that means, I just saw it in a forum!!!)

lspci -vnn | grep '\''[030[02]]'

and get this:

00:02.0 VGA compatible controller [0300]: Intel Corporation 3rd Gen Core processor Graphics Controller [8086:0166] (rev 09) (prog-if 00 [VGA controller]) 01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GF108M [GeForce GT 635M] [10de:0de3] (rev a1) (prog-if 00 [VGA controller])

I installed bumblebee but nothings happens additionally the additional drivers shows me "no propietary Drivers are in use on this system"
