Linux下显卡配置错误 无法进入X Windows的解决


黑呵曰：你不得不感叹Linux的强大。如果windows因为显卡驱动开不了机你会怎么办？重装。。。。Linux提供了一个强大的命令行（windows的那个简直称不上命令行）让你直接修改设置，修改完成不用重启，就能运行。Linux的确比windows好。

进入命令行用vi命令修改以下文件

/etc/X11/Xorg.conf或者可能是/etc/X11/XF86config.conf

修改Xorg.conf是件简单的事，配置文件结构简单，也没有复杂的语法，但是一但配置失败，后果是比较严重的，，所以强烈建议每次修改之前做好备份工作。
Xorg.conf一般位于/etc/X11/xorg.conf
包含了你的显卡信息和显示器信息。
===============sample as my config======================
# /etc/X11/xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the /etc/X11/xorg.conf manual page.
# (Type "man /etc/X11/xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg


装as4.0for 64bit可能出现显示器花屏现象,可以通过:system-config-display    --reconfig修改/etc/X11/Xorg.conf/etc/X11/XF86config.conf还可以通过vncvncserver客户端vncviwer修改Xorg.conf是件简单的事，配置文件结构简单，也没有复杂的语法，但是一但配置失败，后果是比较严重的，，所以强烈建议每次修改之前做好备份工作。
