i know about projects like Bumblebee but i don't need them.
I've got a Lenovo W520 and i can choose in the BIOS which graphics card I'd like to use.
And now my problem:
I've installed the nividia-driver and it work's fine but when I switch to the integrated graphics card (Intel) ubuntu isn't able to detect it. It boots up well but Unity 3D doesn't work which means that there is no 3D-support.
What should I do now?
Thanks for your help!
