在虚拟机VM中安装完Fedora8后，提示安装VMware Tools，在根据提示安装完VMware Tools后结果原来可以用的鼠标滚轮不会动了，不管怎样在什么程序下鼠标滚轮都不能用。
后来经过查找终于发现是VMware Tools修改了 /etc/X11/xorg.conf 文件，在终端中输入 sudo gedit /etc/X11/xorg.conf，以root权限打开文件可以看到文件如下：

注意看上面文件中的红色部份，原来前面没有＃符号，就是因为VMWare
Tools多此一举加了这个XWorkAround驱动导致鼠标滚轮不能使用。现在可以在前面加上＃符号让系统不去执行该行代码，或者干脆删除这四行，然
后保存退出，接着再注销后重新启动XWindow后鼠标滚轮就可以用了。
