I'm Using Ubuntu 12.04.1 LTS on my Optimus-enabled Asus K55v notebook. This means it features two video cards; an integrated Intel one (1GB shared memory), and a discrete Nvidia Geforce 610M. Regarding this, I have a few related questions:
- How can I tell if my system is using the graphic card at all, and if so, how much?
- How do I determine whether the drivers of the Intel graphics are installed or not?
- I tried downloading the drivers from Nvidia's official website, but it did not install. From where do I get the drivers for Nvidia?
- How can I make the best use of the Nvidia graphics card (i.e. in what applications)?
