我在 Ubuntu 21.04 上加载 NVIDIA 驱动程序时遇到问题。结果nvidia-smi是
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver.
Make sure that the latest NVIDIA driver is installed and running.
结果是nvidia-settings：
ERROR: NVIDIA driver is not loaded
ERROR: Unable to load info from any available system
我尝试重新安装最新的 NVIDIA 驱动程序 470.57.02（我当前的内核是5.14.2-051402-generic）。使用 进行安装时sudo apt-get update出现sudo apt-get install nvidia-driver-470此错误：

我尝试用 清除所有 NVIDIA 软件包sudo apt-get purge nvidia-*，sudo apt-get autoremove然后重复该过程，但没有成功。我还尝试在以前的内核（5.11）上安装它，安装以前的驱动程序（nvidia-driver-460），但没有任何效果。
卡被正确检测到。这是输出lspci | grep NVIDIA：

我也尝试过以下解决方案无法安装 nvidia 驱动程序 - 无法找到软件包， 和NVIDIA-SMI 失败，因为它无法与 NVIDIA 驱动程序通信。请确保已安装并运行最新的 NVIDIA 驱动程序，还是没有成功。
有什么建议吗？谢谢！
答案1
我终于成功解决了这个问题。问题确实与安全启动有关。我已经禁用了它，但在此过程中我将启动模式设置为UEFI with CSM而不是普通UEFI。这造成了麻烦。
（w-sky 的回答NVIDIA-SMI 失败，因为它无法与 NVIDIA 驱动程序通信。请确保已安装并运行最新的 NVIDIA 驱动程序给了我提示）
这些是解决我的问题的步骤：
- 在附加驱动程序中，选择 x.org (nouveau) 以停用 NVIDIA 驱动程序。重新启动。
- 启动菜单，选择
UEFI（不是UEFI with CSM！！）并禁用Secure Boot。 - 在附加驱动程序中，再次激活 NVIDIA 驱动程序并再次重新启动。
您可能可以保持安全启动处于启用状态。在这种情况下，设置 NVIDIA 驱动程序时，系统会要求您注册一个新的 MOK 密钥，重新启动后，系统会要求您再次输入该密钥，以授予驱动程序硬件访问权限。我并没有这样做，因为启用安全启动也会阻止 iwlwifi 驱动程序访问我笔记本电脑中的 AX210 wifi 卡。
祝你好运！
