Ubuntu配置3D桌面具體步驟講解:
 
1
我的筆記本是 Thinkpad T43
顯卡是ATI mobility X300
首先更新所有的軟件
sudo apt-get update
sudo apt-get upgrade

2
確定你的顯卡被識別
打開terminal輸入命令
lspci | grep ATI
應該含有 ATI Technologies Inc Radeon R250 [Mobility X300 ..] 等信息
以下是可以裝beryl 的列表

3 配置AIGLX和開源的 ATI 顯卡驅動

注意：如果你已經安裝了fglrx驅動，一定要卸載，在受限制的驅動對話框中把啟動勾掉然后重啟或Ctrl-Alt-Backspace 重啟圖形服務器

打開terminal
輸入
glxinfo | grep vendor

如果出現
server glx vendor string: SGI
client glx vendor string: SGI
OpenGL vendor string: Tungsten Graphics, Inc.
