安装bumblebee解决双显卡笔记本安…

个人建议，装显卡驱动之前先装这俩玩意，要不有可能开机黑屏

安装 linux
source and headers
sudo
apt-get install linux-source
sudo
apt-get install linux-headers-generic

卸载已有驱动
sudo apt-get remove --purge
nvidia*
添加源安装驱动
sudo add-apt-repository
ppa:upubuntu-com/nvidia-unstable

sudo apt-get update

sudo apt-get install nvidia-current
nvidia-settings

解决ubuntu双显卡驱动问题
1.安装大黄蜂bumblebee
sudo
add-apt-repository ppa:bumblebee/stable
sudo
apt-get update
sudo
apt-get install bumblebee bumblebee-nvidia
sudo
bumblebeed –daemon
sudo
reboot
基本都设置好了不需要自己设置什么

查看显卡开启状态
$
lspci|grep VGA

//这个是查看显卡开启状态的命令，后面是ff的，代表关闭

//我的已经装好了，所以独显显示关闭
开启N卡
$
optirun glxspheres

关闭N卡

以上两条命令，关闭窗口就是退出了

显卡设置
$optirun nvidia-settings -c :8

注：ubuntu关于双显卡这块问题不少，我公司配的E430怎么装怎么好使，我自己的本子装完各种黑屏进不去系统，后来我启动时候进命令界面，执行
$ apt-get remove nvidia-experimental-3

//注意，我这命令没完，需要补齐，因为我忘了我卸载的是哪个版本了，反正是个低版本，重启就ok了，这只是解决方法之一，希望对大伙有帮助
