当我使用geditinUbuntu 20.04时，每当我单击 中的任何复选框时Preferences，都不会发生任何事情。
例如，当我单击 时Display line numbers，该复选框仍标记为已选中。出于某种原因，点击Display grid pattern、Enable text wrapping、 和Do not split words over two lines可以，但是当我退出Preferences并重新进入时，它们会回到原来的状态，如图所示。
其他选项卡中的所有其他选项都无法更改。
编辑：作为普通用户使用时显然Preferences有效，而不是root用户。gedit以前，我试图更改Preferences为 root
现在，我想知道为什么 Preferences 不能以 root 身份更改。我注意到，当我gedit以普通用户身份使用时，终端上没有弹出任何内容，但是当我gedit以 root 身份打开时，终端中会显示以下消息：
