XFCE 锁屏问题

Question

TL;DR：您可能想要sudo apt-get remove light-locker light-locker-settings删除 xfce 锁屏。

您的问题是，这xubuntu-desktop是一个元包。单独删除它对您来说没什么用。

安装时，xubuntu-desktop您可以选择允许/拒绝安装一堆其他软件包。如果您忘记了这些软件包是什么（说实话，您怎么会记得呢？），您可以使用以下方法找出它安装的是什么

apt-cache show xubuntu-desktop

这将向您显示有关元包的大量信息。作为参考，我在 xubuntu 14.04 上的结果如下所示（注意，我添加了>>>>>下面解释的强调行）：

请注意我输入的中间的两行>>>>。这些行是安装 xubuntu-desktop 时引入的软件包。这不包括那些软件包引入的软件包等。

现在，如果您想要彻底清除，xubuntu-desktop您必须卸载每一个软件包，而这可能并不是您想要做的。

你最好的解决方案是这样的：

跑步apt-cache show xubuntu-desktop
从 Depends/recommends 列表中找到您不想要的软件包。出于您的目的，删除以开头的所有内容xfce可能会删除您想要的所有内容。但是其中一些软件包（如alsa-base和）alsa-utils很重要，您不想删除它们。也许可以将其与的结果进行比较apt-cache show cinnamon，然后仅删除不重叠的内容（但同样，即使这样也要小心 - 您不想删除太多内容）。
完成所有这些操作后，运行sudo apt-get autoremove以清理所有孤立依赖项

话虽如此，对于您的实际问题，您可能想要这样做sudo apt-get remove light-locker light-locker-settings，因为这些是 xfce/xubuntu 特定的锁屏包。
