變更ubuntu 8.10 解析度

在thinkpad i series 1171-9xt 上安裝完ubuntu 8.10後，
解析度只有 800 x 600，
在【系統】==> 【偏好設定】==> 【螢幕解析度】這設定裡，
螢幕的解析度居然只有 800 x 600 以下可供選擇，
經google 一下，找到了解決方案

修改 /etc/X11/xorg.conf ：
在終端機下輸入

gksudo gedit et/X11/xorg.conf

在跳出的密碼尋問視窗輸入root密碼


編輯 xorg.conf 的內容 ：

將 xorg.conf 的內容全數刪除，
更改為以下內容後，儲存並重開機 ，即有 1024 x 768 的解析度可選擇

# card/monitor can produce)
