问题
我的笔记本电脑的主显示器和外接显示器无法同时使用。根据我使用的驱动程序，笔记本电脑的屏幕要么是空白的，要么是外接显示器未连接或不可用。
细节
笔记本电脑是 HP Omen，配备第 10 代 i7 和 Nvidia GeForce 显卡，显示器是 27 英寸 AOC 显示器。我今天刚刚在上面安装了 Ubuntu 20.04 LTS。我通过 HDMI 线将笔记本电脑连接到显示器。
我尝试过的方法
最初，笔记本电脑的屏幕工作正常，但显示器无法连接。为了解决这个问题，我从 X.org Nouveau 显示驱动程序切换到 Nvidia 460 驱动程序（或 465 - 行为相同）。在我进行此更改并重新启动后，外接显示器已连接，但在启动时显示 Omen 徽标后，笔记本电脑的显示屏空白。

答案1
我可以按照以下步骤解决此问题。
首先我检查了推荐的驱动程序sudo ubuntu-drivers devices，它提供了输出：
== /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 ==
modalias : pci:v000010DEd000024DDsv0000103Csd000088C8bc03sc00i00
vendor : NVIDIA Corporation
driver : nvidia-driver-460 - third-party non-free recommended
driver : nvidia-driver-460-server - distro non-free
driver : nvidia-driver-465 - third-party non-free
driver : xserver-xorg-video-nouveau - distro free builtin
根据此输出，nvidia-driver-460指示为要使用的正确驱动程序。在另一个线程中，人们提到需要启用 Nvidia PRIME 才能使用我想要的设置。我接下来做的是运行命令sudo apt-get install nvidia-driver-460 nvidia-prime。之后，我重新启动了机器，两个显示器都被正确识别，现在一切正常。
