I have a new Dell's laptop E6430 with two VGAs (the Intel and nVidia).

I tried to download the file from the official site of nVidia but it caused the system to crash. I'm now on a new fresh system.

I need detailed instruction for safely installing the driver and also how to switch between the two cards.


Your problem seems to be identical/very similar with this one: How can drivers for Nvidia graphics cards be installed on Ubuntu 13.04 without messing up the OS?

I think the answer I've wrote there might apply in your case as well.

Good luck and let us know what happens!
