- Ubuntu18.04
- CUDA 10.0
- 内核 5.3.0-53-通用
我按照 NVIDIA 的说明将 CUDA 库从版本 10.2 更新到 11.0这里。
GPU 被正确识别为：
$ lspci | grep -i "nvidia"
01:00.0 VGA compatible controller: NVIDIA Corporation Device 1ed0 (rev a1)
01:00.1 Audio device: NVIDIA Corporation Device 10f8 (rev a1)
01:00.2 USB controller: NVIDIA Corporation Device 1ad8 (rev a1)
01:00.3 Serial bus controller [0c80]: NVIDIA Corporation Device 1ad9 (rev a1)
$ nvidia-smi

但是，ubuntu-drivers-common 无法识别新的 nvidia-driver-450：
$ ubuntu-drivers devices
== /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 ==
modalias : pci:v000010DEd00001ED0sv00001028sd000008C4bc03sc00i00
vendor : NVIDIA Corporation
manual_install: True
driver : nvidia-driver-435 - distro non-free
driver : nvidia-driver-440 - third-party free recommended
driver : nvidia-driver-418 - third-party free
driver : nvidia-driver-430 - third-party free
driver : xserver-xorg-video-nouveau - distro free builtin
我想知道为什么会这样？你知道吗？
谢谢。

该ubuntu-drivers实用程序应该显示 Ubuntu 提供的驱动程序。
显示manual_install: True。这意味着您有一个手动安装的驱动程序。这似乎确实是真的 ;-)
我没有发现任何问题。
