run nvidia-xconfig

DO NOT run it !!! 第二天开机时，无法进入图形界面，第一次没有出现迷茫登录界面，而第二次输入密码按回车无反应，后来按 CTL+ALT+F3 进入 tty，删除新创建的该文件，然后重启，恢复正常。

require sudo, otherwise,

$ nvidia-xconfig

after sudo

$ sudo nvidia-xconfig 
[sudo] password for weiya:

but concern about the warning, then I found the explanation in https://askubuntu.com/questions/468098/lost-nvidia-driver
