A。先在系统－系统管理－硬件驱动里选择安装驱动，（本人显示器是LG－17CRT，分辨率1152＊768＿75HZ，显卡是NVIDIA 7300GT－偶选择的是173版本）。显卡SIS的朋友没法开。一般默认推荐安装也可以（装好UBUNTU系统更新＋装汉语包后，点桌面右键－更改桌面背景－视觉效果－正常，系统就会自动推荐驱动，叫你下载安装。） 安好驱动后开起（更改桌面背景－视觉效果－正常）就算开起了特效，重启成就出现显示器分辨率和刷新率问题过低。
为了方便大家能尽快解决分辨率问题，早日享受3D的震撼效果，我将自己实践经验与大家一起分享。
B。在终端里输入以下命令对文件进行编辑：
sudo gedit /etc/X11/xorg.conf
C。输入超级管理员的密码。（如果之前是使用超级管理员账号登入的话，则自动跳过。）
打开后你想要的修改Xorg.conf文件资料。
D。（没安驱动开不起特效，但可以解决你修改Xorg.conf文件错误后还原） /etc/X11/xorg.conf里Ubuntu 8.10原装系统正确文件资料如下：
# 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

（备注：保存后退出重启，这时已经修改）
E。安好驱动后，解决显示器分辨率和刷新率问题过低，打开系统－系统管理－Nvidia X Server settings(ATI没用过），打开X Server Display Configuration后看右边的Display(就是显示器相关设置），分辨率Resolution很低:随便选如： 640＊320或800＊600， 刷新率Configuration：60HZ 然后点下面Save to X Configuration File 打开 Show Preview...
把里面的从# xorg.conf (X.Org X Window System server configuration file)包括一项开始把全部复制粘贴到xorg.conf文件，（同时打开原来的xorg.conf文件清空）。找到下面的这一项Option "metamodes" "800x600_60 +0+0"把它改成Option "metamodes" "1152x864_75 +0+0"（根据自己的显示器分辨率和刷新率来改）保存后退出重启，看看成功没有。如果不行找到这两项改下为
HorizSync 28.0 - 85.0
VertRefresh 43.0 - 76.0
哈哈～你就会发现显示器分辨率和刷新率回到正常了，并开起了特效，重新打开那个显卡设置， 系统－系统管理－Nvidia X Server settings看分辨率可以设更高到1920＊1080或1920＊1200。刷新率也可以设成AUTO或60到85了。
F。嘿～我改了后觉得Too simple,你看后还觉得算简单吧。最后我把我的Xorg.conf文件发出来让大家看看就知道了。哎～NND之前搞这个问题真烦。不过现在一切OK！NO problem,Beautiful.
我的Xorg.conf文件如下：
