sumsung R18上fedora 9总进不去图形界面

先说我的电脑配置：
Notebook information：Sumsung R18
Integral graphics card: ATi Redeon Xpress 1250
Precessors: Intel® Core™ Duo CPU T2450 @ 2.00GHz
Network: Realtek RTL8139/810x Family Fast Ethernet Nic
Atheros AR5006EX wireless Network Adapter
采用grub从windows XP操作系统中硬盘安装到ert3格式分区中，只能进入文本的命令行操作，而在startx后无法进入xwindows，错信息如下：

后来再安装ATi-driver-installer-x86.86-64.run，仍然无法进入图形界面，关于Xorg.conf的配置如下：
