Ubuntu启动时候黑屏的解决

 单位的电脑是集成显卡的，以前没有碰到这样的情况，装好ubuntu 后，装ati的驱动，可一重启就整一个黑屏 ，系统 已经启动 好了，可就是看不到x界面。。。

       在网上查了一堆攻略，失败了无数次后总算成功了，现在把偶的血泪过程总结下：

       1、安装完ubuntu后，直接安装：系统－－》系统管理 －－》硬件驱动，选择ubuntu列出的ati驱动安装，然后重启

        2、如果能正常启动那是最好，如果黑屏了，则ctrl＋alt＋f1进入shell 界面，然后打开/etc/X11/xconf.org这个文件 ，对着下面的提示进行修改：
# xorg.conf (X.Org 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 xorg.conf manual page.
# (Type "man 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.
#
# Note that some configuration settings that could be done previously
# in this file, now are automatically configured by the server and settings
# here are ignored.
#
# 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

Section "Monitor"

Section "Device"

然后重启应该就ok了～～
如果出现xconf解析错误之类的提示，那就说明添加的时候语法不对～～，变量和值之间都是tab要注意了～～
