我看到了关于更新后 nvidia 驱动程序的其他一些答案（sudo apt update和sudo apt upgrade）。但我的 nvidia 安装不再起作用
例如：
- 我的第二台显示器通过 USB-C 适配器连接，无法再工作
nvidia-smi返回我
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
- 我不能再使用 CUDA
>>> import torch
>>> torch.cuda.is_available()
False
我尝试了一些答案，所以我prime-select query这样做了prime-select on-demand，因为按需是我唯一的选择。
但是我的驱动程序已安装：
dpkg -l | grep "nvidia-"

所以我有正确的驱动程序（？）nvidia-driver-535因为 ubuntu 说这是我的 GPU 运行的驱动程序ubuntu-drivers devices
另外，我的外接显示器也出现了问题，我必须将 ubuntu 配置为使用集成 gpu (amd) 来运行桌面应用程序，并将我的 nvidia GPU 仅用于 CUDA
如何解决我的实际问题以恢复此行为？
答案1
我刚刚找到了答案：
sudo dkms autoinstall
就我而言，它有效
