我通过yum update -y升级fc8，居然把我的核心升级到fc9了，出现问题。
usb鼠标无法使用，只能用笔记本自带的触摸板。请求解决方案。就算再 grub引导时选择fc8，还是不能使用usb鼠标了，没更新的时候一切正常。
以下是系统相关信息：

没人帮忙，害我重装。

我添加后x界面无法启动了，只能进命令行。
另外，谁有xorg.conf原始文件，麻烦贴一个上来。我刚才自己改，不是很清楚vi的用法，结果现在里面有问题了。
另外，关于我的usb鼠标的问题，在命令行下面正常，能够使用。
谢谢谢谢。

我的貌似不是这个问题。我的有鼠标显示，但是usb鼠标拖动不了，就是说显示的其实是我的笔记本自带的触摸板，而不是我的usb鼠标。触摸板能正常使用，就是usb鼠标不行。
不知道该怎么办。先谢谢了。

Fedora安装后没有鼠标的解决办法
当安装完成Fedora后，发现没有鼠标显示，但是鼠标可以用，只是看不到而已。解决办法。
在终端中使用root用户来解决。
打开终端：
＃gedit /etc/X11/xorg.conf
出现编辑界面后，找到 Section "Device"
在EndSection 前面输入Option "HWCursor" "false"
例如：
Option "HWCursor" "false"
EndSection
然后保存，并且关闭。重新启动X就可以了。
