為了方便大家能盡快解決分辨率問題，早日享受3D的震撼效果，考試大實踐經(jīng)驗與大家一起分享。
在終端里輸入以下命令對文件進(jìn)行編輯：
sudo gedit /etc/X11/xorg.conf
輸入超級管理員的密碼。（如果之前是使用超級管理員賬號登入的話，則自動跳過。）
打開后你想要的修改Xorg.conf文件資料。
（沒安驅(qū)動開不起特效，但可以解決你修改Xorg.conf文件錯誤后還原） /etc/X11/xorg.conf里Ubuntu 8.10原裝系統(tǒng)正確文件資料如下：
# 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

E。安好驅(qū)動后，解決顯示器分辨率和刷新率問題過低，打開系統(tǒng)－系統(tǒng)管理－Nvidia X Server settings(ATI沒用過），打開X Server Display Configuration后看右邊的Display(就是顯示器相關(guān)設(shè)置），分辨率Resolution很低:隨便選如： 640＊320或800＊600， 刷新率Configuration：60HZ 然后點下面Save to X Configuration File 打開 Show Preview...
把里面的從# xorg.conf (X.Org X Window System server configuration file)包括一項開始把全部復(fù)制粘貼到xorg.conf文件，（同時打開原來的xorg.conf文件清空）。找到下面的這一項Option "metamodes" "800x600_60 +0+0"把它改成Option "metamodes" "1152x864_75 +0+0"（根據(jù)自己的顯示器分辨率和刷新率來改）保存后退出重啟，看看成功沒有。如果不行找到這兩項改下為
HorizSync 28.0 - 85.0
VertRefresh 43.0 - 76.0
哈哈～你就會發(fā)現(xiàn)顯示器分辨率和刷新率回到正常了，并開起了特效，重新打開那個顯卡設(shè)置， 系統(tǒng)－系統(tǒng)管理－Nvidia X Server settings看分辨率可以設(shè)更高到1920＊1080或1920＊1200。刷新率也可以設(shè)成AUTO或60到85了。
