Steps to turn off discrete graphics card in CentOS 6.5

Be sure to write down the steps this time. Every time you reinstall the system, it takes a lot of time to turn off the independent graphics

Operating system: CentOs 6.5 32-bit

Graphics card model:

Integrated display: Intel Corporation 3rd Gen Core processor Graphics Controller

Independent graphics: NVIDIA Corporation GF108M [GeForce GT 630M]

The main thing here is to turn off the independent graphics and only use the integrated graphics to solve the serious problem of heating.

First resolve various dependencies

yum install -y libbsd-devel libbsd glibc-devel libX11-devel help2man autoconf git tar glib2 glib2-devel kernel-devel kernel-headers automake gcc gtk2-devel

rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org

rpm -Uvh http://www.elrepo.org/elrepo-release-6-6.el6.elrepo.noarch.rpm

yum install kmod-r8168

yum --disablerepo=\* --enablerepo=elrepo install kmod-nvidia

Download two files here first

1) libturbojpeg-1.2.1-3.i586.rpm

2) libfltk1.1-1.1.9-1pclos2007.i586.rpm

After downloading is complete

rpm -ivh **** Install these two packages

Then execute the command:

yum install kmod-nvidia

yum install nvidia-x11-drv

yum install kmod-bbswitch

yum install VirtualGL

yum install bumblebee

After everything is installed, just restart

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)
