1 安裝或更新NVIDIA驱动
- 安装之前先卸载已经存在的驱动版本
sudo apt-get purge nvidia* - 只有在禁用掉 nouveau 后才能顺利安装 NVIDIA 显卡驱动，禁用方法就是在 /etc/modprobe.d/blacklist-nouveau.conf 文件中添加一条禁用命令，首先需要打开该文件，通过以下命令打开
sudo vim /etc/modprobe.d/blacklist.conf
按G后跳转到最后一行，追加blacklist nouveau
:wq保存退出
sudo update-initramfs -u执行该命令后生效 - 重启后关闭桌面服务，安装驱动
sudo reboot
sudo service lightdm stop - 使用标准Ubuntu仓库进行自动化安装显卡驱动
