ubuntu14.04 Nvidia 驱动和cuda安装(转)

1. 安装build-essentials

安装开发所需要的一些基本包

sudo apt-get install build-essential

2. 安装NVIDIA驱动

2.1 准备工作

在关闭桌面管理 lightdm 的情况下安装驱动似乎可以实现Intel 核芯显卡 来显示 + NVIDIA 显卡来计算。

具体步骤如下：

1. 进入Ubuntu， 按 ctrl+alt+F1 进入tty， 登录tty后输入如下命令

sudo service lightdm stop

该命令会关闭lightdm。如果你使用 gdm或者其他的desktop manager 请在安装NVIDIA驱动前关闭他。

2. 屏蔽cpu集显

sudo vim /etc/modprobe.d/blacklist.conf

添加以下内容：

vga16fb

nouveau

rivafb

nvidiafb

rivatv

2.2 安装驱动

下载与计算机显卡匹配的驱动源<文件名>.run

sudo sh ./<文件>.run

3. 安装CUDA 6.5

下载CUDA 6.5. 

然后通过下列命令, 将下载得到的.run文件解压成三个文件, 分别为

• CUDA安装包: cuda-linux64-rel-6.5.14-18749181.run
• NVIDIA驱动: NVIDIA-Linux-x86_64-340.29.run
• SAMPLE包: cuda-samples-linux-6.5.14-18745345.run

这里不安装NVIDIA驱动

cuda6.5.run --extract=extract_path

注意, 需要通过下面命令给所有.run文件可执行权限

chmod +x *.run

 

3.1 安装CUDA

通过下列命令安装CUDA, 按照说明一步一步安装至完成.

sudo ./cuda-linux64-rel-6.5.14-18749181.run

3.1.1 添加环境变量

安装完成后需要在/etc/profile中添加环境变量, 在文件最后添加:

PATH=/usr/local/cuda-6.5/bin:$PATH
export PATH

保存后, 执行下列命令, 使环境变量立即生效

source /etc/profile

3.1.2 添加lib库路径

在 /etc/ld.so.conf.d/加入文件 cuda.conf, 内容如下

/usr/local/cuda-6.5/lib64

执行下列命令使之立刻生效

sudo ldconfig

 

3.2 安装CUDA SAMPLE

首先安装下列依赖包

sudo apt-get install freeglut3-dev build-essential libx11-dev libxmu-dev libxi-dev libglu1-mesa-dev

然后用下述命令安装sample文件

sudo ./cuda-samples-linux-6.5.14-18745345.run

完成后编译Sample文件, 整个过程大概10分钟左右

cd /usr/local/cuda-6.5/samples
sudo make

 全部编译完成后， 进入 samples/bin/x86_64/linux/release, sudo下运行deviceQuery

sudo ./deviceQuery

如果出现下列显卡信息， 则驱动及显卡安装成功：

./deviceQuery Starting...
