    Switch video card

    I'm running Ubuntu on my Asus K95V which has two graphics card:
    Code:
    lspci | grep VGA
    00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
    01:00.0 VGA compatible controller: NVIDIA Corporation GF108M [GeForce GT 630M] (rev ff)
    How do I find out which one is being used at the moment and how can I switch between them? Also I'm not sure if I should use Bumblebee.
    Thanks for any help.

    With Optimus, they're both powered on, but only the intel is being used. Yes, you want to use bumblebee: https://wiki.ubuntu.com/Bumblebee

    Thank you Temüjin. I run glxgears with optirun and the difference is evident. Now, what do I have to do if I want nvidia card to be used by default by all applications?
