我最近使用 apt 将 KDE 安装在我的 Ubuntu 10.04 机器上。（即apt-get install kde-desktop）
过了一段时间，我对测试感到厌倦，想再次使用 gnome。因此，我使用 Synaptic 包管理器删除了系统上的所有 kde4 组件，并且与 KDE 桌面环境相关的所有内容都被删除了。（或者我是这样认为的……）
但完成所有这些操作并重新启动后，加载屏幕（或启动画面）仍然显示“Kubuntu”。而且当我使用 gnome 时，除了我应该看到的合法（gnome）鼠标指针外，我还会看到 KDE 鼠标指针。（氧气主题）
我删除 KDE 的方式有什么问题？为什么我会看到已删除的桌面环境的残余。

答案2
两个建议
检查 psychocats纯洁的侏儒不确定他是否是维护 wiki 的人，但在删除这些软件包之前，显然要检查软件包列表以确保你确实要删除它们。
在 gedit 中打开 /var/log/apt/history.log 并检查 kde-desktop 的安装，所有同时安装的软件包或在几秒钟/几分钟内安装的软件包将作为 kde-desktop 的依赖项添加，列出列表检查两次.....（嘿，现在是十二月）然后删除那些软件包。
希望这两个选项都能帮到您。

这里唯一的问题是我丢失了 VLC 播放器、GIMP 和一些其他程序，这些程序不是与 kde4 一起安装的，也不是 kde4 的依赖项。最重要的是，原始问题仍然存在。 :-( 安装丢失的程序不是问题，因为没有丢失不可恢复的数据，但我仍然很难理解这个过程出了什么问题。。
更新 我之前有点不耐烦...重启后确实修复了问题...所以我现在要做的就是下载并安装 VLC、GIMP 和其他丢失的程序..
