ubuntu16.04下安装NVIDIA驱动出现循环登陆问题
首先是在英伟达的官网上查找你自己电脑的显卡型号然后下载相应的驱动。
网址:http://www.nvidia.cn/page/home.html
然后下载下来之后,在ubuntu下按ctrl+alt+f1进入命令行界面,
然后在命令行界面下输入:
sudo service lightmd stop //这个是关闭图形界面
然后卸载掉原有驱动:
sudo apt-get remove nvidia-*
驱动一般为.run文件,给驱动run文件赋予执行权限:
sudo chmod a+x NVIDIA-Linux-x86_64-xxx.run
安装:
sudo ./NVIDIA-Linux-x86_64-xxx.run -no-x-check -no-nouveau-check -no-opengl-files //只有这样安装才不会出现循环登陆的问题
重启
reboot
重启之后显卡驱动便安装好了
