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

it only returned one entry, the integrated one:

I was wondering, why he didnt recognize the nvidia card, but found out that he sees the card, when I accidently ran

It showed

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:

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

still only shows the intel graphics...

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

You have to install bumblebee for dual graphics

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.

unfortunately i cant disable it within the bios....

I dont understand why they dont unlock all bios functions on a laptop, only on a desktop....
