我最近买了一台新的华硕 ROG Strix 笔记本电脑，并全新安装了 Ubuntu 22.04。一切都很顺利，直到我通过 HDMI 插入了第二台显示器。无论如何我都无法让它工作。我的笔记本电脑的规格如下。
Ubuntu 甚至无法检测显示器本身。这是xrandr

即使我进入显示设置，它也显示只有内置显示器已连接。
我已经按照说明安装了 NVIDIA 显示驱动程序这在我遇到这个问题之前，答案就已经说明了。（我尝试了关于这个问题的所有答案，这也)

Nvidia 设置：
即使我单击也没有发生任何事检测显示器。
我也尝试在这台笔记本电脑上安装 Debian。它遇到了完全相同的问题。我的最终目标是能够将我的第二台显示器与 Ubuntu 一起使用。
