ubuntu下nvidia驱动安装不上，求教！！

goldfish

我在/etc/apt/source.list里加入了以下几个源(是自己学校的源)

deb http://mirror.udlchina.org/ubuntu/ dapper main restricted universe
multiverse

deb-src http://mirror.udlchina.org/ubuntu/ dapper main restricted universe

multiverse
deb http://mirror.udlchina.org/ubuntu-cn/ dapper main restricted universe  

multiverse

然后在终端运行：sudo apt-get install nvidia-glx nvidia-settings

出现以下信息：是不是源的配置有问题？好像说找不到包，谢谢指点。

看上面的提示让我apt-get update ，可是sudo apt-get update升级2.6.12到2.6.15之后就进不了系统了，
选了多重启动菜单之后立即花屏（就是应该出现loading module的那个画面），这个

又是什么原因阿，今天装了n遍系统了，还是搞不定，大家帮忙指点一下，谢谢
