Ubuntu 18.04LTS Nvidia-driver-396安装

系统 ubuntu18.04.1 LTS， 显卡：GTX1080 Ti x4块

【卸载】

sudo apt-get autoremove --purge nvidia*

【安装】

• 首先禁用nouveau，将blacklist nouveau追加到/etc/modprobe.d/blacklist.conf

在文件末尾添加：

blacklist nouveau

options nouveau modeset=0

• 通过PPA方式自动安装
  首先，添加PPA。 可选：添加新的源，请见：添加新源。

  sudo add-apt-repository ppa:graphics-drivers/ppa

  sudo apt-get update

接下来查看适合的Nvidia-driver：

ubuntu-drivers devices

比如查到： nvidia-driver-396 recommended

进入tty（命令行模式）Ctrl+alt+F3 （F3/4/5/6）若进不了tty模式请见后：突发问题。

sudo service lightdm stop
sudo apt-get install nvidia-driver-396
sudo reboot

如果提示： Error bad status return for module on kernel:类似的错误，那么请将你的GCC 和 G++升级到和你内核原带的版本。有可能因为编译其他东西降级GCC、G++。

重启后，检查是否安装成功：

nvidia-smi

nvidia-settings

添加新源

国内有很多Ubuntu的镜像源，包括阿里的、网易的，还有很多教育网的源，比如：清华源、中科大源。
我们这里以中科大的源为例讲解如何修改Ubuntu 18.04里面默认的源。
编辑/etc/apt/sources.list文件, 在文件最前面添加以下条目(操作前请做好相应备份)：
