关于ATI的OpenGL的驱动问题。

今天搞了一通，终于成功打开了OpenGL的驱动，在OpenGL模式下玩SuperTux稳定在99FPS左右，挺高兴的。但重启之后，就出问题了，玩SuperTux变得一顿一顿的，跟没装驱动的时候一样，用系统自带的OpenGL程序查看如下图示，用glxinfo查看的结果如下：
大侠们能看出什么问题吗？我觉得它们显示的结果好像相反了。

請問你是不是在登出後再登入, 如果是的話, 就是你的KDM reset了X, 仁還unload了ati的kernel module,
所以就發生這事?

要改kdmrc (/etc/kde/kdm/kdmrc), 將 #TerminateServer=true 改為 TerminateServer=true

我的 kdmrc 在 http://www.streamload.com/matthewlam64/files/kdmrc
我其他對 Mandriva 2006 的修改, 請到 http://www.streamload.com/matthewlam..._update.tar.gz
