无法单击 gedit 中首选项中的复选框

当我gedit在使用 时Ubuntu 20.04，无论何时我单击 中的任何复选框Preferences，都不会发生任何事情。

优先

例如，当我单击 时Display line numbers，复选框仍处于选中状态。出于某种原因，单击Display grid pattern、Enable text wrapping和Do not split words over two lines可以正常工作，但当我退出Preferences并重新进入时，它们会恢复到原始状态，如图所示。

其他选项卡中的所有其他选项均无法更改。

编辑：显然，以普通用户身份Preferences使用时有效，而不是 root用户gedit。之前，我试图将Preferences

现在，我想知道为什么不能以 root 身份更改首选项。我注意到，当我gedit以普通用户身份使用时，终端上不会弹出任何内容，但是当我gedit以 root 身份打开时，终端中会显示以下消息：

当启动 GUI 应用程序（例如gedit，使用）时sudo，您必须使用sudo -H，如下所示：

sudo -H gedit /path_to/filename
