xrandr --listproviders 不显示任何图形卡

  • 772

我希望能够xrandr识别我的两张 RTX 3070 Nvidia 显卡。

但是，xrandr 不返回任何内容。

xrandr --listproviders
Providers: number : 0

我正在使用nvidia-prime和nvidia-driver-530。

我相信这是由于Xwayland在其上运行 X 合成层wayland而不是xorg直接运行造成的。

虽然我真的不知道这是否真的wayland是根本原因，但我相信我想wayland在我的服务器机器（Ubuntu Server 22.04）上禁用所有并xorg只运行。ssh -X我正在通过Ubuntu 桌面客户端访问服务器。

xrandr --listmonitors
Monitors: 1
 0: +*XWAYLAND15 3840/620x2160/330+0+0  XWAYLAND15

我需要什么设置或配置才能xrandr --listproviders显示 Nvidia 显卡？

我很乐意根据需要提供更多详细信息。

  1. 您应该使用像lshw和nvidia-smiwhen using这样的应用程序ssh -X，因为它们实际上会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ssh -X时只会显示您的本地显示器和视频卡。xrandr原因是您在运行这些命令时将显示调用转发给本地主机。 lshw并将nvidia-smi在远程系统上正常运行并向您展示您拥有的硬件。

    举个例子，我这​​里有两位主人并排坐着。一个有 GTX 1060，另一个有 GTX 1650：

    本地系统：

    如您所见，xrandr在我的本地主机和远程主机上运行时，该命令将显示完全相同的内容。但是lshw和nvidia-smi显示了我需要在两台主机上看到的内容。

  2. Best Answer

    最终，我试图做的事情似乎是不可能的。

    因为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，所以我安装了lightdm这样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，所有 Nvidia 卡都被识别，一切似乎都运行良好。
