更新后丢失使用 KDE 的选项 - 如何在不丢失配置的情况下将其恢复

Question

在周一运行更新后，在 Kubuntu 12.04 机器上，我失去了在登录屏幕中选择 KDE 的选项（有一条消息大约是“选项 kde* 已被删除”）。只剩下“默认”和“故障安全”。使用“默认”导致黑屏，只有 KDE 风格的鼠标光标可见，使用“故障安全”让我回到登录屏幕。

与此同时，我已经安装了 unity（并gdm随之安装）。然后我尝试

sudo dpkg --reconfigure kdm

但这只会带回 KDE 登录屏幕（带有额外的 GNOME/Unity 会话选项）。看起来可能是某些 KDE 软件包被卸载了，或者某些配置已损坏。关于前者：

我认为某些软件包可能丢失了，但我不确定，而且我不想因为害怕丢失我的 KDE 特定配置和/或使事情变得更糟而进行实验。

在这种情况下：如何在不丢失配置的情况下在登录时恢复 KDE 选项？

Answer 1

也许一些 KDE 包被删除了？

试试sudo apt-get install kubuntu-desktop。
