你好，刚接触 Linux 和这个网站。
我在互联网上寻找答案，但我空手而归，完全不知所措，非常感谢您的帮助，谢谢。我的电脑是旧的 HP XW6400 工作站，配有 gtx1050ti 和 Pop OS 20.04 nvidia iso。已安装 nvidia 驱动程序 440。但它只能在集成显卡上运行。我无法让系统在专用显卡上运行，还有一件有趣的事情是，我有 HDMI 电缆连接到来自专用 GPU 的电视，它确实显示所有内容，但没有声音，但它说它在集成显卡上运行？我的 BIOS 中没有安全启动选项，抱歉我对 Linux 完全是新手。
nvidia x 服务器设置应用程序也会打开一个空白屏幕。我已经安装了最新的 Pop OS 20.04 Nvidia iso。 440 驱动程序，在尝试 20.10 Nvidia iso 后。 455驱动程序版本也有同样的问题。
dwill63@pop-os:~$ nvidia-settings

我遇到的问题是我的 GPU 驱动程序未运行或未被看到 我尝试在 CLI 中运行不同的命令时遇到多个错误，例如
dwill63@pop-os:~$ nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
dwill63@pop-os:~$ sudo system76-power graphics nvidia
setting graphics to nvidia
