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 Code:
00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06) Code:
lspci || grep VGA Code:
01:00.0 3D Controller: NVIDIA Corporation GK106M [GeForce GTX 765M] (rev a1) 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 Am i still missing something, or is this even the right path?? :p |
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.... |
