在Debian-7.1下安装Bumblebee解决双显卡发热问题

1. 修改/etc/apt/sources.list, 使用如下源：

# deb cdrom:[Debian GNU/Linux 7.1.0 _Wheezy_ - Official amd64 DVD Binary-1 20130615-23:06]/ wheezy contrib main

# deb cdrom:[Debian GNU/Linux 7.1.0 _Wheezy_ - Official amd64 DVD Binary-1 20130615-23:06]/ wheezy contrib main

deb http://mirrors.163.com/debian/ wheezy main
deb-src http://mirrors.163.com/debian/ wheezy main

deb http://ftp.cn.debian.org/debian/ wheezy-backports main contrib non-free  
deb-src http://ftp.cn.debian.org/debian/ wheezy-backports main contrib non-free 

deb http://security.debian.org/ wheezy/updates main contrib
deb-src http://security.debian.org/ wheezy/updates main contrib

# wheezy-updates, previously known as 'volatile'
deb http://mirrors.163.com/debian/ wheezy-updates main contrib
deb-src http://mirrors.163.com/debian/ wheezy-updates main contrib

2. 下载并编译bbswitch

因为bumblebee3.0开始使用bbswitch来进行 'Power Management' ，所以我们必须安装好bbswitch.

执行

git clone https://github.com/Bumblebee-Project/bbswitch.git

进入bbswitch目录，执行

make
make load

如果提示 /lib/module/***/build/不存在在话，就需要下载kernel header.

sudo apt-get install linux-headers-$(uname -r)

3. 安装bumblebee：

sudo apt-get install bumblebee-nvidia primus

执行

lspci | grep VGA

看到如下输出：

说明独显已成功关闭。
