前段時間裝了驅動進不到桌面，改回來之後再次嘗試安裝，可是那個安裝說明實在是簡單，我這個絕對新手照著做，每次都是失敗。又找了一個介紹怎麼啟用XGL的，這個很詳細，我弄成功了並且改了一下，發上來給大家參考一下。
P.S:可能是我的9550太不行了，系統提示說：Xgl已啟用，但不能很好地與這張卡共用。要禁用 Xgl 並返回到 2D 桌面，請按下面的“禁用桌面效果”。這將使您注銷並返回到登錄屏幕。 不過好在學會了怎麼開啟XGL了。
1. 先將make、gcc、kernel-source、xgl、compiz全部安裝好
2.到http://www.ati.com/support/driver.html 下載對應你系統架構驅動。
3.在終端執行命令。下面是我執行的命令：
