下载nvidia linux驱动,文件名为：NVIDIA-Linux-x86-1.0-7167-pkg1.run
安装驱动前，打开/etc/inittab这个文件，找到“id:5:initdefault:”，将其中的5(就是两个冒号中间的那个)改为3(将3改回5即可默认从图形界面登陆)，保存，重新启动计算机，在进入登陆界面就是字符终端了。
装驱动: sh ./NVIDIA-Linux-x86-1.0-7167-pkg1.run，之后是一个绿色为主的界面，询问是否接受协议，是否访问ftp服务器查看最新的版本，之后开始安装(这段时间较长)，安装完毕自动退出到字符终端。
此时可以双屏显示一样的内容了，不过xwindow下，不能同时显示,需要改/etc/X11/XF86config文件，然后就可以双屏之间托动窗口了。
