我希望能够xrandr识别我的两张 RTX 3070 Nvidia 显卡。
但是，xrandr 没有返回任何内容。
xrandr --listproviders
Providers: number : 0
我正在使用nvidia-prime和nvidia-driver-530。
我认为这是由于Xwayland在其上运行 X 组合层wayland而不是xorg直接运行造成的。
虽然我不太清楚这是否wayland是根本原因，但我认为我想禁用wayland我的服务器计算机（Ubuntu Server 22.04）上的所有内容并仅运行。我正在通过 Ubuntu 桌面客户端xorg访问服务器。ssh -X
xrandr --listmonitors

我需要进行哪些设置或配置才能xrandr --listproviders显示 Nvidia 显卡？
我很乐意根据需要提供更多详细信息。

在使用时，您应该使用lshw和等应用程序，因为它们实际上将在您的远程系统上运行，向您显示该系统中的硬件。 在远程系统上运行时，只会显示您的本地显示器和视频卡。原因是，当运行这些命令时，您正在将显示调用转发到本地主机。 和将在远程系统上正常运行，并向您显示您拥有的硬件。nvidia-smissh -Xssh -Xxrandrlshwnvidia-smi
举个例子，我这里有两台并排的主机。一台有 GTX 1060，另一台有 GTX 1650：

如您所见，该xrandr命令在本地主机和远程主机上运行时显示的内容完全相同。但lshw和nvidia-smi在两台主机上显示的正是我需要看到的内容。
答案2
最终，我尝试做的事情似乎无法实现。
由于我不认为图形软件应该以这种方式在无头 Ubuntu 服务器上运行，因此我安装了它，lightdm以便我可以访问服务器机器上的 GUI，并通过直接视频连接将其直接连接到显示器。
安装 GUI 后，一切似乎都运行正常，所有 Nvidia 卡都被识别。
