但

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.

the nvidia bug report starts off with a bunch of failed conftests:
 #error acpi_walk_namespace() conftest failed!
     ^
   /tmp/selfgz20040/NVIDIA-Linux-x86_64-455.23.05/kernel/conftest/functions.h:64:2: error: #error wait_on_bit_lock() conftest failed!

    #error radix_tree_replace_slot() conftest failed!

and then finishes with general errors:
./arch/x86/include/asm/bug.h:35:22: error: expected identifier or '(' before string constant
  asm_inline volatile("1:\t" ins "\n"

    这是我的猜测：你用 5.5 版本替换了默认的 gcc 编译器（8.4？），令人惊讶的是，Nvidia 驱动程序不再成功编译。
    假设您实际上需要 Nvidia 驱动程序 455（标准 Ubuntu 存储库尚未提供），并且驱动程序构建实际上可以在 Ubuntu 上运行，撤消 gcc 上的替代方案，使用名为 gcc、g++、ar、ranlib 等的链接到旧版本你的 ...CUDA/bin 目录（它应该在你的 PATH 中的第一个）。
    使用正确版本的系统 gcc，至少 Nvidia 驱动程序应该能够工作。

    要覆盖用于 CUDA 工作的 gcc，而不更改系统用于更新视频模块之类的内容，请参阅 运行 cuda 示例程序以进行矢量添加的步骤？
    以下是相关段落的删减：

    首先阅读 CUDA 安装指南中的 Ubuntu 部分：例如https://docs.google.com/viewer?url=https%3A%2F%2Fdocs.nvidia.com%2Fcuda%2Fpdf%2FCUDA_Installation_Guide_Linux.pdf&pdf=true

    第 6 章中关于设置环境变量 PATH 和 LD_LIBRARY_PATH 的建议表明您的 cuda 添加应该位于现有 PATH 的开头。这允许您通过简单地将 ...cuda/bin 的链接添加到您想要的版本来使用旧版本覆盖系统 g++ 或 gcc。您要做的最后一件事是更改系统默认编译器——当内核更新发生时，它可能无法成功更新您的视频驱动程序。如果您所做的一切都可能使用旧编译器，请继续并在您的 .profile 中修改您的 PATH 设置，这样每次登录您的 cuda 路径都会设置好。如果您只希望您的 CUDA 工作使用旧编译器，请在需要时将 PATH、LD_LIBRARY_PATH 修改放入脚本中以获取源代码。
