正确版本的Nvidia和Cuda

在（最终）在14.04安装了cuda之后，我没有破坏我的nvidia驱动程序，我试图validation安装。

首先我必须安装nvcc，

sudo apt-get install nvidia-cuda-toolkit 

设置环境

 export PATH=/usr/local/cuda-7.5/bin:$PATH export LD_LIBRARY_PATH=/usr/local/cuda-7.5/lib64:$LD_LIBRARY_PATH 

安装样品

 cuda-install-samples-7.5.sh ~ cd ~/NVIDIA_CUDA-Samples_7.5/0_Simple/vectorAdd make ./vectorAdd 

但是对于这最后一个命令，我收到此错误：

 CUDA driver version is insufficient for CUDA runtime version 

一些产出，

和nvcc -V给出，

这是否意味着我需要cuda v5.5而不是v7.5？ 我需要重新启动并卸载v7.5并安装v5.5？
