解决方法：
对于出错说明：http://fedoraproject.org/wiki/Bugs/FC6Common
方法：
引用:su -c "yum install yum-utils"
yumdownloader kernel-2.6.18-1.2849.fc6.i686
su -c "rpm -Uvh --replacefiles --replacepkgs kernel-2.6.18-1.2849.fc6.i686.rpm"
之后再次以root运行
引用:yum install kmod-nvidia
可以成功安装，然后重启，让新内核生效，再次进入Gnome，系统－首选项－Desktop Effects启动就可以了。
