如何删除所有安装的KDE痕迹
我有两台装有Ubuntu的电脑，但我安装了KDE，为用户提供了另一种选择。 由于Unity已经很好地实现了，所以现在还没有必要使用KDE。 如何在一次扫描中删除所有与KDE相关的软件包，释放空间以及Ubuntu中与KDE相关的任何内容，包括在PC启动或关闭后覆盖ubuntu的徽标，因为在安装KDE之后，Kubuntu徽标是默认的。 如何使用简单的短命令行或GUI工具完全恢复所有KDE内容。
注意 – 我问这个是因为开始逐个选择与KDE桌面环境相关的每个包，检查它是否与任何GTK有关，检查每个包的依赖关系等是非常耗时的。 删除包kubuntu -desktop不会删除随其安装的每个已安装的KDE包，因为这是一个伪包，它安装了其余的真实包，但没有卸载它们，这让我想知道为什么包可以安装一大堆其他包但不能使用一些添加的选项卸载它们以实际卸载它们而不仅仅是虚拟包本身。
您可以使用此命令（从此处 ）完全删除KDE：

install ubuntu-desktop 但是，如果您在安装KDE后手动安装了特定于KDE的程序，则必须单独删除这些程序，然后运行sudo apt-get autoremove 。
警告：正如Munim所说 ，这将删除大量软件包，并可能删除在KDE之前（或在KDE之后但与其分开）安装的软件包以及作为KDE的一部分安装的软件包。 这可能偶尔会产生不可预测的结果，例如包配置问题。
syserss已经写了一些解释 ， 说明在删除这些软件包后，您可能需要采取的一些进一步操作，以使您的系统按照您希望的方式工作。
（我在下面引用它，但为了便于阅读，将引文格式更改为嵌入式链接。）
上述步骤将删除所有KDE软件，但不一定会将系统恢复到KDE之前的安装状态。 我还需要执行两个步骤来将系统还原到kubuntu-desktop的预安装。
第一个是修改Plymouth配置以删除“Kubuntu”启动画面（这只是装饰性的，但仍然令人烦恼和不洁，在Ubuntu中显示在启动时显示’Kubuntu’ ）：
sudo update-alternatives --config default.plymouth sudo update-initramfs -u第二个是恢复lightdm配置使用unity-greeter而不是kde-plasma-greeter。 首先运行此命令打开lightdm配置页面 –
sudo gedit /etc/lightdm/lightdm.conf然后编辑/替换这些行：greeter-session=unity-greeter user-session=ubuntu我从KDE拼凑的最后一步覆盖了lightdm登录屏幕和如何返回原始统一ubuntu的登录屏幕？ 。
我更喜欢以下删除的简单性：
apt-get remove kdelibs-bin kdelibs5-data
craigevil Debian论坛上的craigevil 。 （ http://forums.debian.net/viewtopic.php?f=10&t=102884 ）
这里的问题是，通过专注于构建几乎所有KDE的两个软件包，其余的KDE也会被卸载，因为它们依赖于上述内容。
如果您使用的是ubuntu 15.10或更早版本，则此命令很有用：
sudo apt-get remove kubuntu
如果您使用的是Ubuntu 16.04和Plasma 5，请按照以下步骤操作
sudo apt purge kubuntu-desktop sudo apt autoremove sudo add-apt-repository --remove ppa:kubuntu-ppa/backports
现在好多了。
安装以前的桌面环境（它应该在缓存中，所以你不需要下载任何东西）
sudo apt install ubuntu-desktop
您仍将在启动屏幕上看到kubuntu。 所以要删除它
sudo update-initramfs -u
重启。
在登录屏幕上，选择除KDE之外的桌面会话
最后删除所有kde的痕迹
sudo apt remove --purge kubuntu-desktop sudo apt autoremove
如果你仍然看到kde登录界面（很少）
sudo dpkg-reconfigure gdm3 sudo apt remove --purge sddm
将gdm3替换为当前桌面环境的显示管理器。 ubuntu常见的是gdm，lightdm
从Ubuntu论坛或终端中查看：
sudo apt-get remove kde-full && sudo apt-get autoremove
- 注意（见评论），这可能是不完整的，但是一个良好的开端。
不知道这是否是正确的方式，因为我是初学者，但这对我有用。
sudo apt-get remove kde*
