X31
Ubuntu 710 桌面3D特效無法開啟？移除 fglrx 或 ati官方的驅動程式，刪除 xorg.conf （刪除前先備份，以防萬一），讓 x自己重新抓。

啟動 compix-fusion後， ooo 變成總是全螢幕，沒有 window title bar？ 安裝advance desktop effects settings（CompizConfig Settings Manager, ccsm），然後在utility分類的 workgrounds 選項中，不要勾選 legacy full screen support

一些提醒的地方：
在xorg.conf 中，把
Driver "radeon" #原本使用 ati ，改為 radeon 似乎支援比較多的3D功能
Option "AGPSize" "16" #我的X31 內建的顯示卡記憶體大小是 16MB
Option "AGPMode" "2" #限制在AGP 2X mode，改善顯示晶片穩定度
加到 Section "device" 中。

放上我的 xorg.conf 供參考

# Fallback X.org config file
# FIXME: include the wacom devices (would only add noise at the current
# development stage)
