无法在 Ubuntu 20.04 上完全安装 GTX 960M 的 nvidia 驱动程序

我有一台配备 GTX 960M 的联想 Y700 笔记本电脑。在 18.04 上，Nvidia 驱动程序运行良好。我升级到 20.04，安装失败。安装似乎有些成功，但我无法连接到驱动程序。

我尝试通过 UI（附加驱动程序工具）和 CLI 删除并重新安装，但没有成功。

$ 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.

答案1

尝试sudo apt autoremove --purge nvidia-driver-440然后sudo apt install nvidia-driver-440。如果问题仅与驱动程序有关，这应该可以解决问题。请让我了解结果。

最好运行sudo apt autoremove --purge nvidia-driver-440 && sudo apt install nvidia-driver-440，因为重新安装驱动程序时可能会丢失显示。
