深度学习系统用Ubuntu 16.04，显卡是一张nVidia GTS450，主要用来做简单实验。用比较新的nVidia显卡驱动和CUDA8。
请看完文章再尝试哦
添加下载源
$ cd /etc/apt/
$ sudo cp sources.list sources.list.bak
$ sudo vi sources.list
把源添加到文件前面，保存

更新一下
$ sudo apt-get update
$ sudo apt-get upgrade
添加显卡驱动的PPA
$ sudo add-apt-repository ppa:graphics-drivers/ppa
然后显示下列信息
Fresh drivers from upstream, currently shipping Nvidia.
## Current Status
Current official release: `nvidia-370` (370.28)
Current long-lived branch release: `nvidia-367` (367.57)
For GeForce 8 and 9 series GPUs use `nvidia-340` (340.98)
For GeForce 6 and 7 series GPUs use `nvidia-304` (304.132)
## What we're working on right now:
- Normal driver updates
- Help Wanted: Mesa Updates for Intel/AMD users, ping us if you want to help do this work, we're shorthanded.
## WARNINGS:
This PPA is currently in testing, you should be experienced with packaging before you dive in here:
Volunteers welcome! See also: https://github.com/mamarley/nvidia-graphics-drivers/
### How you can help:
## Install PTS and benchmark your gear:
sudo apt-get install phoronix-test-suite
Run the benchmark:
phoronix-test-suite default-benchmark openarena xonotic tesseract gputest unigine-valley
and then say yes when it asks you to submit your results to openbechmarking.org. Then grab a cup of coffee, it takes a bit for the benchmarks to run. Depending on the version of Ubuntu you're using it might preferable for you to grabs PTS from upstream directly: http://www.phoronix-test-suite.com/?k=downloads
## Share your results with the community:
Post a link to your results (or any other feedback to): https://launchpad.net/~graphics-drivers-testers
Remember to rerun and resubmit the benchmarks after driver upgrades, this will allow us to gather a bunch of data on performance that we can share with everybody.
If you run into old documentation referring to other PPAs, you can help us by consolidating references to this PPA.
If someone wants to go ahead and start prototyping on `software-properties-gtk` on what the GUI should look like, please start hacking!
## Help us Help You!
We use the donation funds to get the developers hardware to test and upload these drivers, please consider donating to the "community" slider on the donation page if you're loving this PPA:

OK
下面就可以开始安装显卡驱动了，下载速度有点慢。
$ sudo apt-get update
$ sudo apt-get install nvidia-367
$ sudo apt-get install mesa-common-dev
$ sudo apt-get install freeglut3-dev
驱动安装完成一定要重启系统
下载并安装CUDA
进入CUDA官网，注册并登陆账号，按照下图配置下载Ubuntu的安装文件，文件约1.4GB。
cuda.png
下载完成进入下载目录，创建一个临时文件，使用命令解压到临时文件中并安装。
$ sudo mkdir /opt/temp
$ sudo sh cuda_8.0.44_linux.run --tmpdir=/opt/temp/
安装协议可以使用q跳过，显示第一个问题询问是否安装驱动。因为前面我们已经安装了驱动，所以我们不安装。

在这里根据不同系统会有2个或4个文件缺失。我的缺了两个文件。
Missing recommended library: libXi.so
Missing recommended library: libXmu.so
使用apt补一下，参考自 stackoverflow。
$ sudo apt-get install nvidia-modprobe freeglut3-dev libx11-dev libxmu-dev libxi-dev libglu1-mesa-dev
安装完成要重启系统，然后再重新安装CUDA包。因为我在这里掉坑了，所谓我建议你们先看文章再尝试。正常的话就不会在显示文件缺失，然后安装成功。

Please make sure that
- PATH includes /usr/local/cuda-8.0/bin
- LD_LIBRARY_PATH includes /usr/local/cuda-8.0/lib64, or, add /usr/local/cuda-8.0/lib64 to /etc/ld.so.conf and run ldconfig as root
To uninstall the CUDA Toolkit, run the uninstall script in /usr/local/cuda-8.0/bin
Please see CUDA_Installation_Guide_Linux.pdf in /usr/local/cuda-8.0/doc/pdf for detailed information on setting up CUDA.
***WARNING: Incomplete installation! This installation did not install the CUDA Driver. A driver of version at least 361.00 is required for CUDA 8.0 functionality to work.
To install the driver using this installer, run the following command, replacing <CudaInstaller> with the name of this run file:
sudo <CudaInstaller>.run -silent -driver
Logfile is /opt/temp//cuda_install_2299.log
安装完毕后声明一下环境变量，并将其写入到~/.bashrc的最后
export PATH=/usr/local/cuda-8.0/bin${PATH:+:${PATH}}export LD_LIBRARY_PATH=/usr/local/cuda-8.0/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
测试
使用nvidia-smi检查显卡状况。
