F9,ATI X2300，3D问题

首先我下了ati-driver-installer-8-10-x86.x86_64.run，之后＃sh ati-driver-installer-8-10-x86.x86_64.run －buildpkg Fedora/F9, 无法生成别人说的4个rpm包,提示是需要kernel-devel之类的,之后我就装了(yum -y install kernel-devel),之后顺利生成4个rpm包,安装rpm过程中又出现问题,提示说libstdc++.so.5 is needed....之后又装了这个(yum install libstdc++.so.5),之后4个包都顺利装上.重启后就有问题了,在命令行登陆界面狂闪约10秒,之后还是没能进图形界面,运行glxinfo之类的都提示:unable to open display....,xorg.conf文件内容如下,不知该如何修改才能进图形界面,各位大大帮帮忙.
