更新后使用KDE的丢失选项-如何在不丢失配置的情况下将其带回来

Question

在周一运行更新后，在Kubuntu12.04框上，我失去了在登录屏幕中选择KDE的选项(有一条消息显示“选项kde*已被删除”)。只有“默认”和“故障安全”仍然存在。使用“默认”导致只有KDE样式的鼠标光标可见的黑色屏幕，使用“故障安全”使我回到登录屏幕。

同时，我已经安装了统一(以及gdm )。然后我尝试

sudo dpkg --reconfigure kdm

但是这只带回了KDE登录屏幕(带有额外的GNOME/Unity选项)。看起来要么是某个KDE包被卸载了，要么是一些配置被破坏了。关于前者：

我认为有些包可能丢失了，但我不确定，我不想实验，害怕失去我的KDE特定的配置和/或使事情更糟。

在这种情况下:如何在登录时恢复KDE选项而不丢失我的配置？

Answer 1

也许KDE包被移除了？

试试sudo apt-get install kubuntu-desktop。
