install driver without bumlbebee

Hi!

Maybe someone can tell me if its possible to install driver directly on hybrid laptop, who have nvidia 525m and intel HD 3000 graphic cards.(now iam using bumlbebee).

When i tried earlier to install it directly it killd my X server.

And if there is way how to install. Please can you give me manual .
