This Lenovo Z570 laptop comes with NVIDIA GEforce GT520M with optimus technology.

I'm trying to install CUDA on Ubuntu 10.10. I downloaded a dev driver from the NVIDIA site.

After installation X server is not started. Nothing is displayed on screen, however i'm able to login through recovery mode(by using failsafeX).

How can this be solved?
