Ubuntu NVIDIA显卡驱动+CUDA安装(多版本共存)
NVIDIA显卡驱动
1.禁止集成的nouveau驱动
solution 1 (recommand)
# 直接移除这个驱动（备份出来）
mv /lib/modules/3.0.0-12-generic/kernel/drivers/gpu/drm/nouveau/nouveau.ko /lib/modules/3.0.0-12-generic/kernel/drivers/gpu/drm/nouveau/nouveau.ko.org
# 更新来禁用nouvea
sudo update-initramfs -u
# 重启
sudo reboot
# 查看版本
cat /proc/versionsolution 2
sudo vim /etc/modprobe.d/blacklist-nouveau.conf
# 在该文件后添加一下几行：
blacklist nouveau
options nouveau modeset=0
# 更新来禁用nouvea
sudo update-initramfs -u
# 重启
sudo rebootsolution 3
# 如果不允许修改，修改属性命令
sudo chmod 666 /etc/modprobe.d/.d/blacklist.conf
# 用gedit编辑器打开blacklist.conf
sudo gedit /etc/modprobe.d/blacklist.conf
# 在该文件后添加一下几行：
blacklist rivafb
blacklist vga16fb
blacklist nouveau
blacklist nvidiafb
blacklist rivatv
# 更新来禁用nouveau
sudo update-initramfs -u
# 重启
sudo reboot2.卸载以安装NVIDIA显卡驱动
sudo apt-get remove --purge nvidia*
sudo sh ./驱动名.run --uninstall 3.安装NVIDIA显卡驱动
solution1 apt安装(recommand)
# search the recommand driver, 384 is recommanded for my PC
sudo ubuntu-drivers devices
# install driver
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-384 nvidia-settings
reboot
nvidia-smi
# 安装Nvidia Prime 双显卡切换指示器
sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install prime-indicatorsolution2 手动安装
sudo /etc/init.d/gdm stop # 或者 sudo service lightdm stop
sudo chmod +x NVIDIA**.run
sudo sh ./驱动名.run -no-x-check -no-nouveau-check -no-opengl-files
sudo /etc/init.d/gdm start # 或者 sudo service lightdm start其他相关命令
nvidia-smi
nvidia-settings
lspci|grep VGA
lsmod|grep nvidia
cat /proc/driver/nvidia/version
sudo lshw -c videoCUDA、CUDNN安装
cuda
solution1（recommend）
若是使用深度学习框架，强烈推荐使用anaconda。用conda安装tensorflow/pytorch的GPU版本时，会自动安装相应版本的cuda、cudnn，安全可靠还方便。若想使用不同版本的cuda，只需创建一个新的conda 虚拟环境，重新安装即可。可参考https://blog.csdn.net/DreamLike_zzg/article/details/88575308
solution2 手动安装
cuda8.0 https://developer.nvidia.com/cuda-80-ga2-download-archive
# choose and download :(local)deb Base Installer for Ubuntu
# cd Downloads
sudo dpkg -i cuda-repo-ubuntu1604-8-0-local-ga2_8.0.61-1_amd64.deb
sudo apt-get update
sudo apt-get install cuda
# after installation, open the bashrc
sudo gedit ~/.bashrc
# the following configure should be added in bashrc
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib64
export PATH=$PATH:/usr/local/cuda/bin
export CUDA_HOME=$CUDA_HOME:/usr/local/cuda
# active
source ~/.bahsrc
# check cuda version
cat /usr/local/cuda/version.txt
# test
cd /usr/local/cuda-8.0/samples/1_Utilities/deviceQuery
sudo make
sudo ./deviceQuery cuda9.0 https://developer.nvidia.com/cuda-toolkit-archive
安装第一个cuda时Installer Type无所谓，但安装第二个cuda时建议选择runfile[local]
# 安装相关依赖
sudo apt-get install freeglut3-dev build-essential libx11-dev libxmu-dev libxi-dev libgl1-mesa-glx libglu1-mesa libglu1-mesa-dev
# 运行runfile文件
sudo sh cuda_9.0.176_384.81_linux.run#..一堆协议说明...,直接按q退出协议说明.
Do you accept the previously read EULA?: accept/decline/quit: accept #接受协议

Finished copying samples.安装完成后，symbolic link：/usr/local/cuda 指向 /usr/local/cuda-9.0。
切换cuda时，重新建立软连接
sudo rm -rf cuda
sudo ln -s /usr/local/cuda-9.0 /usr/local/cuda查看当前cuda版本
cat /usr/local/cuda/version.txt安装 cuda-toolkit
sudo apt install nvidia-cuda-toolkit
nvcc --versioncudnn7
cuda与cudnn关系：https://www.jianshu.com/p/622f47f94784
删除原有cudnn，直接终端输入
sudo rm -rf /usr/local/cuda/include/cudnn.h
sudo rm -rf /usr/local/cuda/lib64/libcudnn*下载cudnn
