How to disable dedicated graphics card in my notebook?


Hi,

I have a notebook with 2 graphic cards, one being within the haswell processor, one being a dedicated nvidia card running CentOS 6.5. Now I've been googling a bit how to deactivate the nvidia one to reduce battery usage and heat production (thus having no noisy fan blowing), but I haven't been able to succeed so far...

When i first used

Code:
lspci | grep VGA
it only returned one entry, the integrated one:

Code:
00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)
I was wondering, why he didnt recognize the nvidia card, but found out that he sees the card, when I accidently ran

Code:
lspci || grep VGA
It showed

Code:
01:00.0 3D Controller: NVIDIA Corporation GK106M [GeForce GTX 765M] (rev a1)
So I thought, maybe the drivers need to be installed to get control over the card, so I went ahead and installed the driver using the guide from post 2:

http://www.linuxquestions.org/questi...le-4175456123/

with a bit more googling, I succeded in installing the nvidia drivers, but using

Code:
lspci | grep VGA
still only shows the intel graphics...

Am i still missing something, or is this even the right path??

I dont want to use both graphic cards, so that the dedicated kicks in when perfomance is needed and shuts down when not.

I want to disable the dedicated card completely. Do i still need this?

Have you tried disabling it from the BIOS?

On my desktop I have the integrated graphics, disabled by BIOS, so lspci only shows my 2 ATI cards.

I rather doubt there is a way to load balance video like that.

You may be able to telinit 3 and then change settings then go back to telinit 5.

Usually you would just disable it from the BIOS.
