从kdm启动kde时遇到以下问题?

zsdicky

大概如下:
.kde/share/config/kwinrc  not writable.
.kde/share/config/kbuildsycocarc  not writable.
.kde/share/config/ksplashrc  not writable.
.kde/share/config/kwinrc  not writable.
.kde/share/config/kpersonalizerrc  not writable.

No write access to '/home (/)
不能进入kde(3.4.1)
初接触linux,开始以为没有文件权限,但好像不是的,
问题会是出在哪里呢?
