感谢以下回答如何删除 xubuntu-desktop？，我知道如何删除 Xubuntu 桌面。
但我担心从我的 Ubuntu 安装中删除 Xubuntu 可能会影响或损害 Unity 桌面环境。我的这种担心合理吗？
答案1
您引用的问题的答案链接到此网站，http://www.psychocats.net/ubuntu/pureubuntu
该网站称：
这些删除命令是根据添加到默认 Ubuntu 安装中的 Kubuntu、Xubuntu 等软件包创建的。这些命令可能会删除您添加到默认安装中并希望保留的一些其他软件包。如果是这种情况，请跟踪这些软件包并重新安装它们。理论上，您的设置应该仍然存在。我对您对 *buntu 安装造成的任何损害概不负责。如果您担心会破坏任何东西，请对您的 *buntu 安装进行完整备份。
是的，命令可能导致某事出错。
例如，你使用的某些程序可能恰好是 Xubuntu 中默认安装的，你可能想要保留这些程序，在删除 Xubuntu 安装的所有内容的命令中

如果您正在使用它，您可能想要保留gimp它，因此请查看列表以便知道它正在删除什么。
答案2
正如解释的那样更改桌面环境会影响我的程序/个人数据吗？，安装（或删除）给定的桌面环境不应影响您系统上现有的任何其他桌面环境。它只是安装/删除一堆软件包，确保它们apt彼此独立（两个不同的软件包不能在完全相同的路径中安装完全相同的文件）。
也就是说，这取决于如何你开始卸载程序。例如，如果你认为这lightdm是 Xubuntu 的一部分并删除它（不要！），而你没有其他display manager可用的，那么你的系统可能会变得不可用。因此，如果你遵循其他建议删除非常具体的软件包列表的答案，请确保手动检查每个软件包，确保其中没有任何可能对系统至关重要的东西。
现在，对于一个真正安全的删除方法（就我所知）Xfce，如果我想在我的系统上执行此操作，我会按如下方式进行：

现在前你继续在上面选择“是”，仔细查看软件包列表，找出你不想删除的软件包（例如blueman和Thunar），列出清单。删除完成后，重新安装这些软件包：
apt-get install blueman thunar
这是最安全的删除方式Xfce，回到你最初的问题，应该不会影响现有的安装Unity。至于剩余的部分Xubuntu，请遵循其他答案并单独评估每个软件包的删除。
