我尝试过的事情：
- 清除并重新安装 nvidia-driver-455。
- 清除 nvidia-driver-455 并安装 nvidia-driver-450
- 尝试切换到内核 5.4.0-52-generic
答案1
安装与正在运行的内核相关的标题为我解决了这个问题。
sudo apt-get install linux-headers-`uname -r`
在我的情况下，它安装了这两个包
- Linux 标头-5.4.0-53
- Linux 标头-5.4.0-53-通用
答案2
在我的情况下，您还必须为特定的 nvidia 驱动程序安装额外的模块..
Nvidia 驱动程序版本：455
内核：5.8
linux-headers-5.8.0-32-generic
linux-hwe-5.8-headers-5.8.0-32
linux-hwe-5.8-tools-5.8.0-32
linux-image-5.8.0-32-generic
linux-modules-5.8.0-32-generic
linux-tools-5.8.0-32-generic
linux-modules-extra-5.8.0-32-generic #<- 必需
linux-modules-nvidia-455-5.8.0-32-generic #<- 必需
对于 cuda，请按照以下手册操作
https://developer.nvidia.com/cuda-downloads
并选择从网络安装选项
欢呼吧，

已解决：如何在 Ubuntu 20 下安装 nVidia 驱动程序
最初关注本文，在经历了这一切之后，我得到了和 OP 一样的东西：
在网上搜索了好几天试图解决这个问题，最后终于找到了这篇文章，尤其是 Martin M 的上述回答。
对我来说关键是这一步：
sudo apt install linux-generic
当此命令完成后，你应该得到如下所示的终端式 GUI。在此屏幕上，你可以集成/更新 UEFI 和报名参加 MOK，选择设置安全启动密码。要选择密码，请使用 Tab 键在密码字段和文本链接之间切换。
完成后立即重新启动：
sudo reboot now
重新启动后，您会看到一个蓝屏，询问您是否要继续启动或注册 MOK，这并不明显，但在这一步，选择注册 MOK并输入您在上一步中输入的安全启动密码。
完成后，你应该在运行时正确看到你的显卡详细信息
sudo nvidia-settings
上面的截图显示我仍然有这个错误：
RROR: nvidia-settings could not find the registry key file or the X server is not accessible. This file should have been installed along
with this driver at /usr/share/nvidia/nvidia-application-profiles-key-documentation. The application profiles will continue to work,
but values cannot be prepopulated or validated, and will not be listed in the help text. Please see the README for possible values
and descriptions.
但驱动程序现在已正确加载。仍在研究注册表项文件错误的影响。
答案4
使用网络安装来安装 cuda 为我解决了这个问题。
您可以按照此处的说明进行安装：https://developer.nvidia.com/cuda-downloads
