还有个奇怪的问题就是 ，我安装nvidia的驱动 用的是一个外国人写 的脚本，每次执行完这个脚本后我就可以进入x,不知道这是为什么？？
脚本如下：
#!/bin/bash
# Licence GPL
# Written by Tseliot
# Alpha release
# Version 0.02a
# For 64 bit ONLY!!!
function installer {
echo -n "Do you want to install or uninstall the Nvidia driver 8756? (Type "i" to install or "u" to uninstall) (or press CTRL+C to exit)"
read inst
