如何删除Unity以外的所有桌面环境？
我正在使用Ubuntu 12.04与许多桌面环境，如Unity，Gnome，Lubuntu，Xubuntu，Cinnamon等等。 现在我想删除除Ubuntu以外的所有内容，因为它们都在搞乱我的主要统一桌面。 所以我想保留ubuntu-desktop并希望删除所有其他。
假设您使用此处引用的PPA进行安装，您可以使用以下命令删除Cinnamon及其依赖项 ：
sudo apt-get install ppa-purge sudo apt-get purge --auto-remove cinnamon sudo apt-get autoremove sudo ppa-purge ppa:gwendal-lebihan-dev/cinnamon-stable 要删除Xubuntu-Desktop及其相关软件包：

删除Gnome-Shell / Gnome-Fallback及其相关包：

清理任何现在不必要的.deb包和库：
sudo apt-get autoclean
确保所有包依赖项仍然完好（在升级现有包时）：
sudo apt-get update && sudo apt-get dist-upgrade
这样做的图形方式是通过Synaptic Package Manager，您可以在那里过滤选项并删除需要从其他桌面删除的所有软件包。
示例：在过滤栏中，您可以找到Kubuntu-Desktop，单击它然后您将看到安装在那里的所有软件包，您可以选择您需要/想要删除的软件包
哦，你可以从软件中心安装Synaptic
现在，通常产生问题的不是桌面环境，它应该是与特定依赖关系相关的东西，并且这些将在删除DE后保留。 无论如何，转到synaptic并删除lubuntu-desktop等。
但我担心这不是你真正的问题。 尝试找到真正原因的依赖。 编辑问题，以准确描述问题所在
删除相关的* ubuntu-desktop，然后自动删除未使用的依赖项
sudo apt-get remove --purge lubuntu-desktop sudo apt-get autoremove
那应该够了
这样做的确定方法就像@Andrea Olivato所说，你可以在一行中完成。
最近我安装了kubuntu ， xubuntu和lubuntu 。
Synaptic Package manager在删除所有可用依赖项方面存在局限性。
以下代码适用于xubuntu-desktop ， lubuntu-desktop和kubuntu-desktop ，所有这些都在一行中
sudo apt-get remove --purge kubuntu-desktop lubuntu-desktop xubuntu-desktop && sudo apt-get autoremove -y
如果您最终安装了更多桌面环境，则可以随时添加更多名称。 有关所有可用桌面环境的列表，请参阅此 Google搜索链接。
