我对 Linux 还很陌生，现在我开始使用 Ubuntu 17.04，因为我不喜欢 Unity UI，所以我决定测试一些桌面环境。
首先我测试了 gnome，但我也不喜欢它，所以我选择了 DDE，哇，它看起来很漂亮，而且功能也很齐全。
所以我决定坚持使用它，但是窗口框架仍然像纯 gnome 一样显示并且不遵循 DDE 界面：
我首先想到的是删除 gnome 桌面安装，以便一切恢复正常。所以我运行了sudo apt remove ubuntu-gnome-desktop，现在我无法在会话启动时选择 gnome 桌面环境，但框架仍然存在。
所以我的问题是，如何让我的窗口框架遵循与系统其余部分相同的 UI 模式？
运行apt list --installed打印一些带有 gnome 前缀的包，我应该删除它们吗？
