关于升级系统补丁后的，出现的问题。gdk

Maburycn

请教各位，每次我安装完Ubuntu 7.10后，马上上网升级安全补丁，安装完补丁，再次重新启动，在界面提示下，输入用户名后就会出现
  

Your session only lasted less than 10 seconds.If you have not logged out yourself,this could mean that there is some installation problem or that you may be out of diskspace.Try logging in with one of the failsafe sessions to see if you can fix this problem.

点击“View detail”后，出现一下提示，希望大家帮我看看，看能否解决这个问题，这个问题我自己不能解决，每次都这样。

    不能进入界面，但是利用alt+ctrl+F1~F6,可以进入字符界面，但是不知道怎么来修改这个错误。

是不是我这个问题提得太傻，还是这个问题太难了？
