环境：ubuntu14.04 64bit
安装驱动
从https://www.nvidia.cn/Download/index.aspx?lang=cn下载对应的驱动：
执行run包提示以下错误：
先安装gdm工具包：
$sudo apt-get install gdm
然后停止X Server:
$ sudo service gdm stop
gdm stop/waiting
注意这里不能像网上其他人说的那样执行sudo /etc/init.d/gdm stop，这样是不能停止X Server的。
禁止掉nouveau驱动：
$ sudo vim /etc/modprobe.d/blacklist.conf
在最后加入“blacklist nouveau”
重启机器
然后再次执行$ sudo ./NVIDIA-Linux-x86_64-390.59.run
执行完成后，执行以下命令确认驱动安装成功：
$ sudo nvidia-smi

安装CUDA软件包
$ wget https://developer.download.nvidia.com/compute/cuda/7.5/Prod/local_installers/cuda_7.5.18_linux.run
安装成功后有如下提示：
Driver: Not Selected
Toolkit: Installed in /usr/local/cuda-7.5
Samples: Installed in /home/hank/Downloads/NVIDIA, but missing recommended libraries
然后修改环境变量：
在/etc/profile文件末尾添加以下两句：
export PATH=$PATH:/usr/local/cuda/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib64
测试：
$ nvcc -V
