这是我第一次在我的计算机上进行双启动，并且我成功安装了 ubuntu。然而，在ubuntu中，我好奇地下载了lubuntu（因为有人说lubuntu感觉有点慢，所以速度更快），不幸的是，我喜欢ubuntu最后的布局并习惯了它。然而，重新启动后，它甚至不让我选择是否以 ubuntu 或 lubuntu 启动，它会自动以 lubuntu 启动，我讨厌 T_T
我没有放置登录屏幕，因为这是我自己的计算机，我想知道是否有办法改回 ubuntu。请！如果你能一步一步解释，我会无限感激，因为我还不是专业程序员或 ubuntu 专业人士！
谢谢你！

首先你需要删除以下所有软件包，然后需要再次安装ubuntu，

之后尝试安装 ubuntu，
sudo apt-get install --重新安装 ubuntu-desktop
