NVIDIA and CUDA with OPTIMUS

Hi! I have an ASUS A53S with a NVIDIA GeForce GT220MX. I'm trying to test pyrit with CUDA but when i put pyrit list cores my NVIDIA dont appear. I've installed NVIDIA drivers with this:

but when i go glxinfo | grep -i "direct rendering" this happen:
Xlib: extension "GLX" missing on display ":0.0".
Xlib: extension "GLX" missing on display ":0.0".
Xlib: extension "GLX" missing on display ":0.0".
Xlib: extension "GLX" missing on display ":0.0".
Xlib: extension "GLX" missing on display ":0.0".
Error: couldn't find RGB GLX visual or fbconfig
Xlib: extension "GLX" missing on display ":0.0".
Xlib: extension "GLX" missing on display ":0.0".
Xlib: extension "GLX" missing on display ":0.0".

Xlib: extension "GLX" missing on display ":0.0".
Xlib: extension "GLX" missing on display ":0.0".
Xlib: extension "GLX" missing on display ":0.0".

I searched on google and it says that the problem is because i have no bumblebee for my Optimus, but i cant install bumblebee.
Thanks

Can't install bumblebee? did you add the sid repo?

I wrote the steps I used to get it to work here

I never managed to get cuda to work through, but i'm feeling ambitious at the moment so i'll give it a go
