如何将外接显示器设置为默认值？

Question

我已通过 HDMI 将外接显示器连接到我的笔记本电脑。目前，当我选择“两者中的相同图像”时，我的桌面要么扩展到外​​部显示器（具有原始分辨率），要么同时扩展到两个低分辨率。

如何确保默认使用外接显示器而笔记本电脑显示器只是空白。

我通过执行以下操作生成了 xorg.conf 文件：

X-配置

以下是我的用户文件夹中生成的 xorg.conf.new 文件的内容。我应该在任何地方复制这个吗？我应该编辑内容吗？

我看到你有英特尔驱动程序。您根本不再需要 xorg.conf。

只需插入外部显示器，进入显示器设置并按照您想要的方式配置显示器：

然后单击“设为默认”。此后，每当您连接外部显示器时，Ubuntu 都会自动检测并自动更改显示设置。
