完全删除旧的 Nvidia 驱动程序
Eat*_*ate 13 uninstall nvidia graphics drivers 18.04
我最近安装了全新安装的 Ubuntu，并通过 nvidia-driver-390 下载了一些 Nvidia 驱动程序。我注意到还安装了 nvidia-340（作为“二进制驱动程序”而不是“驱动程序元包”）。有趣的。后来，我安装了 nvidia-driver-396。我想删除版本340和390，所以我只能用396我已经使用sudo apt remove --purge nvidia-340 nvidia-390和卸载也有些相关的包（的nvidia-common，nvidia-current，nvidia-settings，nvidia-prime，nvidia-kernel-common*，等），在这一点上，我只是想删除所有从我的系统跟踪 Nvidia 驱动程序并重新开始。不幸的是，在包含的“软件和更新”中，仍然列出了驱动程序 340、390 和 396。附上截图。谢谢你的帮助。

注意：所以你必须删除ppa才能完全删除它？

注意ubuntu-drivers devices命令输出 - 有以下几行：
driver : nvidia-340 - third-party free
driver : nvidia-driver-390 - third-party free
driver : nvidia-driver-396 - third-party free recommended
driver : xserver-xorg-video-nouveau - distro free builtin
这些行意味着您可以使用来自第三方存储库的 nvidia 340、390、396 驱动程序和来自发行版存储库的开源 nouveau 驱动程序。只向您推荐一名司机。该列表并不意味着所有提到的驱动程序都已安装在您的系统中。它仅表示安装驱动程序的潜在可能性。该列表不能手动更改，因为它是由ubuntu-drivers旨在自动检测、检查和安装可用的 Ubuntu 存储库的专有驱动程序的实用程序形成的。
因此，要更改列表，必须删除第三方存储库，在特定情况下这是专有的 GPU 驱动程序存储库。但极不推荐这样做，因为您的目标是无论如何都要保留 nvidia 396 驱动程序，并从自动创建的 nvidia 340 和 390 驱动程序列表中删除。如果您删除第三方存储库，则只会检测到可用的发行版驱动程序，在特定情况下只有 340 和 390 - 因此，您将获得最不适合您的情况。
我对你的建议是什么都不做。您的系统看起来很健康，一切正常。
如果您喜欢实验，请遵循以下指南。
以下描述仅用于实验目的 - 如果您不确定，请不要这样做！
按Ctrl+Alt+F4，登录并删除所有 nvidia 员工：
sudo apt remove nvidia-*
接下来删除专有 PPA GPU 驱动程序存储库。在终端运行：
sudo add-apt-repository --remove ppa:graphics-drivers/ppa
sudo apt update
然后检查终端中的可用驱动程序：
ubuntu-drivers devices
您会看到第三方 nvidia 驱动程序已经消失，只有发行版 nvidia 驱动程序可用。在驱动程序中，nvidia 396 将不存在，因为该驱动程序不是 Ubuntu 发行版存储库的一部分。
添加您的 PPA 专有 GPU 驱动程序存储库：
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update
再次安装您想要的 nvidia 396：
sudo ubuntu-drivers autoinstall
重启：
sudo reboot
重新启动后，键入nvidia-smi将显示有关您的图形卡的不同信息，如下所示：
xyz@xyz-workstation:~$ nvidia-smi

对于具有 nvidia-prime 的系统，如果它返回错误，则键入sudo prime-select intel然后重新启动，然后键入sudo prime-select nvidia然后再次重新启动。现在输入nvidia-smi，它应该可以工作。此方法适用于大多数具有内核的系统，直到 5.4
