I have two graphics card in my laptop.

enter image description here

However, I am unable to activate the NVIDIA one. I need to use it, because the integrated Intel card can't connect through DVI/HDMI.

I have the drivers installed, however I am unable to "select" the NVIDIA card.

How do I enable the second graphics card?

enter image description here

While running as suggested gives

sudo: nvidia-xconfig: command not found

Trying to install nvidia-xconfig fails as there's no such package.

I would give Bumblebee a try, although HDMI ports are a bit of a hit-and-miss sometimes:
How well do laptops with Nvidia Optimus work?

Well I installed it and it enables me to run applications using the optirun command. What I was looking for is to be able to connect to external monitors using VGA or HDMI. Is there an easy way to do that? – mreq Jun 11 '12 at 8:24
Many laptops have the ability to do that, since most of the displaying work is carried by the Intel card, whereas the Nvidia card just does some computations and hands over the results to the Intel card. But there have been cases of problems with HDMI ports in hybrid-graphics laptops. – 719016 Jun 11 '12 at 10:50
I forgot to mention that if you haven't done yet, it would be useful to submit your DSDT information as explained in this website: – 719016 Jun 12 '12 at 8:53
