GTX1080+ ubuntu14.04+cuda8.0 配置安装

安装环境：
-------------------------------------------------------------------------------
1. 操作系统：Ubuntu 14.04 LTS 64位；
2. GPU卡：NVidia GTX1080 Founder Edition
3. 驱动：NVIDIA-Linux-x86_64-367.27.run

-------------------------------------------------------------------------------
安装步骤：
-------------------------------------------------------------------------------
1. 安装Ubuntu
	1.1 开机进入BOIS修改主板默认显卡为内部主板集成显卡；
		Advance Mode->Advanced->System Agent (SA) Configuration->Graphics Configuration->IGFX;
		保存后退出；
	1.2 安装Ubuntu 14.04 LTS 64位；
2. 准备工作
	2.0  更新操作系统
		$ sudo apt-get update
		$ sudo apt-get install build-essential
	2.1 进入系统执行 $ sudo apt-get remove nvidia*
	2.2 关闭当前的nouveau driver，步骤如下：
		2.2.1 You should blacklist the current nouveau driver by editing (or creating) this file:
			$ sudo gedit /etc/modprobe.d/blacklist-nouveau.conf
		2.2.2 在新建文件中加入下面几行代码，write the file with ctrl+o and close the nano editor with ctrl+x:
			blacklist nouveau
			blacklist lbm-nouveau
			options nouveau modeset=0
			alias nouveau off
			alias lbm-nouveau off
		2.2.3 Disable the Kernel nouveau with these lines:
			$ echo options nouveau modeset=0sudo tee -a /etc/modprobe.d/nouveau-kms.conf
		2.2.4 After that enter the following command:
			$ sudo update-initramfs -u
		2.2.5 重启系统，以确定系统是否将nouveau禁用；
			$ sudo reboot
		2.2.6 验证？lsmod | grep nouveau

3. 安装驱动
	3.1 进入tty，关闭lightdm
		CTRL+ALT+F1; login
		$ sudo /etc/init.d/lightdm stop
	3.2 切换到驱动所在路径
		$ sudo sh NVIDIA-Linux-x86_64-367.27.run
	3.3 按指示安装
		3.3.1 根据提示，选择accept, ‘yes’或默认选项，
			选项：Accept → Continue → installation → OK → OK → OK 
		3.3.2 At the end you are asked whether you want to save your new X configuration. Agree to that. 
		注：报错the distribution-provided pre-install script failed!不必理会，继续安装；
	3.4 启动lightdm（此步骤可能不是必须，上步安装完直接reboot跳过此步）
		$ sudo /etc/init.d/lightdm restart, 或者
		$ sudo service light restart
 	3.5 重启开机进入BOIS修改主板默认显卡为独立显卡；
		Advance Mode->Advanced->System Agent (SA) Configuration->Graphics Configuration->Auto;
		保存后退出；
	3.6 进入系统，检验驱动是否安装成功
		3.6.1 打开终端，输入以下命令：
			$ cat /proc/driver/nvidia/version
			如果显示驱动版本，说明安装成功。
		3.6.2 在系统搜索中键入'navidia'，会出现“NVIDIA X Server Setting”软件，点击进入了查看显卡信息。


3、 Cuda8.0安装
1) sudo sh cuda_8.0.27_linux.run 
   
   accept n y y 
2) 安装所缺少的库
sudo apt-get install freeglut3-dev build-essential libx11-dev libxmu-dev libxi-dev libgl1-mesa-glx libglu1-mesa libglu1-mesa-dev
3) sudo apt-get install vim
4) 设置环境变量,在终端输入这两句：
export PATH=/usr/local/cuda-8.0/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-8.0/lib64:$LD_LIBRARY_PATH
sudo vi /etc/profile
export PATH=/usr/local/cuda-8.0/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-8.0/lib64:$LD_LIBRARY_PATH
sudo ldconfig      //环境变量立即生效
5)验证成功
nvidia-smi 
nvcc –V
6)测试cuda的samples
cd ‘/home/NVIDIA_CUDA-8.0_Samples’
make 
7) 安装cudnn5.0 
tar -zxvf cudnn-8.0-linux-x64-v5.0-ga.tgz
sudo cp cuda/include/cudnn.h /usr/local/cuda/include/
sudo cp cuda/lib64/libcudnn* /usr/local/cuda/lib64/
sudo chmod a+r /usr/local/cuda/include/cudnn.h
sudo chmod a+r /usr/local/cuda/lib64/libcudnn*
8) 验证
/usr/local/cuda/bin/cuda-install-samples-8.0.sh ~/cuda-samples
cd ~/cuda-samples/NVIDIA*Samples
make -j $(($(nproc) + 1))
bin/x86_64/linux/release/deviceQuery
