哪个版本适合 Ubuntu 20.04 的正确 Nvidia 设置？

尝试在更新后安装最新的 Nvidia/CUDA，驱动程序工具指向 340.108（专有，已测试），但我尝试安装 cuda Ubuntu 软件包...现在我得到了

如果允许的话我更喜欢 460 但为什么这会发生冲突 - 我是否需要删除并重新安装，就像我在有问题的旧 Nvidia 系统上所做的那样？

需要明确的是，“nvidia-cuda-toolkit”在 Ubuntu focal 20.04 上需要 libnvidia-compute-460，但工具中安装的驱动程序是 nvidia-340（“附加驱动程序”选项卡中的“专有，已测试”），这是除 Nouveau 开源驱动程序之外的唯一选择。为什么？

可能的解决方法：

  • 安装失败后，可以用DPKG“--force-overwrite”修复：

    apt-get -o Dpkg::Options::="--force-overwrite" install --fix-broken

  • 作为安装命令行的额外标志：

    apt-get -o Dpkg::Options::="--force-overwrite" install nvidia-cuda-toolkit

无论您喜欢使用哪种工具，似乎都可以在以及Dpkg::Options的命令行上提供相同的参数。aptapt-get
