在安装新驱动程序之前，我是否必须删除当前的 Nvidia 驱动程序？

  • 772

我在混合 Nvidia 笔记本电脑上使用 Ubuntu 18.04，并带有 Ubuntu 打包的 Nvidia 390 驱动程序。我想升级到版本 410 驱动程序，所以我添加了图形驱动程序 PPA 并尝试安装它们，因为我在网上找到的所有地方都建议你只需要这样做。相反，apt 大喊安装新驱动程序会导致的大量依赖问题：

这些问题看起来很真实——aptitude why-not说 390 驱动程序与 410 驱动程序的几乎每个部分发生冲突（直接或间接）。在这种情况下：

  • 在安装 410 驱动程序之前是否需要卸载 390 驱动程序？（大概是这样的apt purge nvidia-driver-390 && apt autoremove --purge？）
  • 使用 Nvidia GPU 时这样做是否安全？如果我无法安装新的驱动程序怎么办？

  1. Best Answer
    1. 需要...不。建议...是的。一般系统会先删除有冲突的包，比如旧的驱动，然后再安装新的包。
    2. 是的。系统将回退到通用驱动程序。

    如果我无法安装新的驱动程序怎么办？

    您再次安装旧版本。您可能遇到的唯一真正问题是系统在启动期间崩溃。在这种情况下，您可以从 grub 救援中删除驱动程序。

    如果一切都失败了......重新安装。因此，在您做任何事情之前，请备份您的所有个人文件。
