我正在运行多个 GPU (GTX 1060 x6)，但其中两个没有响应。我使用 lspci -nnk（下面的输出）查询驱动程序，结果显示 4 个 GPU 具有“正在使用的内核驱动程序：nvidia”，而另外两个 GPU 没有列出“内核驱动程序”。我在 4.4.0-104-generic 上运行 Ubuntu 16.04 LTS，并安装了用于张量流的 CUDA 8.0 和 nvidia-387 驱动程序（开源）。有什么想法为什么内核驱动程序没有显示吗？

答案1
更新：解决方案是扰乱 BIOS 以打开所有 PCIe 通道以供使用以及使用“Above 4G Decoding Enabled”
答案2
您需要摆脱“nouveau”模块/驱动程序。
假设您使用的是 gnome，打开“软件和更新”->“其他驱动程序”并将其更改为“NVIDIA 二进制驱动程序”之一
如果这对您不起作用，唯一的选择是通过此处记录的黑名单方法。
