![20.04.1 LTS 丢失驱动程序(可能是实时更新?)](https://linux22.com/image/1177483/20.04.1%20LTS%20%E4%B8%A2%E5%A4%B1%E9%A9%B1%E5%8A%A8%E7%A8%8B%E5%BA%8F%EF%BC%88%E5%8F%AF%E8%83%BD%E6%98%AF%E5%AE%9E%E6%97%B6%E6%9B%B4%E6%96%B0%EF%BC%9F%EF%BC%89.png)
经过一番努力,我成功安装了 20.04 LTS,并且完全正常运行。实时更新似乎是个好主意,所以我启用了它。我通常让工作站 24/7 全天候开机。几个小时前,我试图用它观看 YouTube 视频,但我的 Sound BlasterX G6 没有声音。昨天它运行正常。
当我发现我的 NVIDIA 驱动程序也丢失时,我重新启动以检查 dmesg 输出。Ubuntu 以 640x640 分辨率启动,而不是 2560x1440。我重新安装了 NVIDIA 驱动程序并恢复了以前的分辨率。我找不到如何重新安装安装时自动安装的 Sound BlasterX G6 驱动程序。
有人能分享如何恢复我的声音的指导吗?另外,是什么原因导致我的所有驱动程序都被删除了?

经过 Google 搜索后,我发现其他人也遇到了此硬件的问题。
我检查了上次启动时的 dmesg,看到以下内容:

根据上面的 dmesg 输出,我关闭了工作站。当我重新打开电源时,我的音频输出又恢复了工作。
我唯一的问题是为什么我的 NVIDIA 驱动程序被删除了?

运行软件更新程序后,我现在知道为什么我今天早上刚安装的驱动程序被删除了:
我刚刚发现 nvidia-450 是适用于我的硬件的驱动程序。为什么要删除这些驱动程序?我将运行更新程序,重新启动,然后查看是否再次丢失 2560x1440 分辨率。如果是,这就是我丢失它的原因。
