这次一定要把步骤给记下来，每次重装系统，为了关闭独显花费了大量时间

操作系统：CentOs 6.5 32位

显卡型号：

集显：IntelCorporation 3rd Gen Core processor Graphics Controller

独显：NVIDIACorporation GF108M [GeForceGT 630M]

这里主要是关闭独显，只用集显，解决发热严重的问题。

首先解决各种依赖

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 --importhttps://www.elrepo.org/RPM-GPG-KEY-elrepo.org

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

yum install kmod-r8168

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

到这里先下载两个文件

1)libturbojpeg-1.2.1-3.i586.rpm

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

下载完成后

rpm -ivh **** 安装这两个包

接着执行命令：

yum install kmod-nvidia

yum install nvidia-x11-drv

yum install kmod-bbswitch

yum install VirtualGL

yum install bumblebee

全部安装好后，重启即可

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)

rev ff即表示成功关闭，发热严重问题得到解决
