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.

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.

|
sudo nvidia
-
uninstall
|
如果卸载失败，或者卸载完成后，建议这样做一下
|
1
|
|
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！
