我正在安装ubuntu 20.04 on asus tfu a15.。我已经安装了 cuda 工具包和驱动程序，但 nvidia-smi 仍然不起作用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。
我认为问题出在安装了多个驱动程序版本。以下是dpkg -l | grep nvidia
rc libnvidia-compute-390:amd64 390.138-0ubuntu0.20.04.1 amd64 NVIDIA libcompute package
rc libnvidia-compute-390:i386 390.138-0ubuntu0.20.04.1 i386 NVIDIA libcompute package

ii nvidia-visual-profiler 10.1.243-3 amd64 NVIDIA Visual Profiler for CUDA and OpenCL
如何删除所有驱动程序并仅保留 440？
我尝试过sudo apt autoremove但没有删除任何包。
最后，我手动删除了它们并得到了以下列表：
ii libnvidia-compute-440:amd64 440.100-0ubuntu0.20.04.1 amd64 NVIDIA libcompute package
ii libnvidia-ml-dev 10.1.243-3 amd64 NVIDIA Management Library (NVML) development files

但nvidia-smi仍然不起作用
答案1
