如何将外接显示器设置为默认显示器？

我已通过 HDMI 将外接显示器连接到笔记本电脑。目前，当我选择“两台显示器显示相同图像”时，我的桌面要么扩展到外​​接显示器（具有原始分辨率），要么两台显示器的分辨率都较低。

我如何确保默认使用外接显示器并且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。我应该将其复制到任何地方吗？我应该编辑内容吗？

我看到您有英特尔驱动程序。您根本不再需要 xorg.conf。

只需插入外部显示器，进入监视器设置并按照您想要的方式配置显示器：

在此处输入图片描述

然后点击“设为默认”。此后，Ubuntu 应该会自动检测您何时连接外接显示器并自动更改显示设置。
