Nvidia CUDA 6 Installed In Ubuntu 12.04

环境：ubuntu 12.04 （x64）

如果不能够 service lightdm stop，显示：unknown service 或者其他的 

sudo /etc/init.d/lightdm restart

cuda 6.0

1）Verify You Have a CUDA-Capable GPU

To verify that your GPU is CUDA-capable, go to your distribution’s equivalent of SystemProperties, or, from the command line, enter:

1	lspci | grep -i nvidia

2） Verify the System Has gcc Installed

1	gcc --version

一般系统安装完毕后便自带C编译环境和Python编译环境

3）安装必要的库

If you wish to build allof the samples, including those with graphical rather than
command-line interfaces, you may need to install additional system libraries or
headers if you have not done so before.

1 2	sudo apt-get install freeglut3-dev build-essential libx11-dev libxmu-dev libxi-dev libgl1-mesa-glx libglu1-mesa libglu1-mesa-dev

注：安装libgl1-mesa-* library时可能会提示你缺少依赖包，请谨记安装提示信息中Recommended依赖包，否则，呵呵呵…

4）卸载(禁止)存在的NVIDIA(nouveau)驱动

一般Ubuntu系统安装完毕后，会弹出Additional Driver警示框，提醒安装驱动，为了避免兼容性问题，如果已经安装的请卸载PS：The CUDA 5.5 installers include the CUDA Toolkit, SDK code samples, Nsight Visual Studio edition (for Windows) and Nsight Eclipse Edition (for Linux / Mac OS X), and developer drivers.

1	sudo nvidia-uninstall

如果卸载失败，或者卸载完成后，建议这样做一下

1	sudo apt-get remove --purge nvidia*

禁止开源驱动nouveau的开机加载

1	sudo gedit /etc/modprobe.d/blacklist.conf

在文件后添加如下内容保存后重启

1 2	blacklist nouveau options nouveau modeset=0

5）Installation

Exit the GUI if you are in a GUI environment by pressing Ctrl-Alt-F1 and login as root, then type into the commond below and press Enter

1	service lightdm stop

Install the CUDA Toolkit (xx in 5.5.xx is the minor version of the installation package)by running the downloaded .runfile as a superuser.

1	sudo sh cuda_5.5.xx_linux_32_rhel5.x.run

这个初始化时间有点长，耐心等待…

安装完成后切换回GUI界面

1	service lightdm start

6）Define the environment variables

我习惯用如下方式进行环境变量的添加修改：

首先

1	gedit ~/.bashrc

添加如下内容

1 2	export PATH=/usr/local/cuda-6.0/bin:$PATH export LD_LIBRARY_PATH=/usr/local/cuda-6.0/lib64:$LD_LIBRARY_PATH

然后

1	gedit /etc/ld.so.conf

添加如下内容

1	/usr/local/cuda-6.0/lib64

完成之后执行如下命令

1	sudo ldconfig

验证是否添加路径成功

1	ldconfig -v|grep cuda

以上内容其实在你安装完毕CUDA Toolkit之后的信息中都有所提示！文章最后会给出安装完毕后的截图！

7）关于Bug：

执行 nvidia.settings 出现错误提示框 no driver detected 以及 nvidia driver is activated but not currently in use

不知道怎么解决，郁闷中…反正console project都能运行，只是进入Ubuntu系统时因为驱动未安装好的缘故会花屏而已，另外建议运行一下Samples中的1_Utilities中的deviceQuery程序作为测试！
