我需要采取哪些进一步的故障排除步骤？我该怎么做才能让内核识别显卡？

根据 terdon 的回答，如果我运行命令，我会收到以下消息：
dthacker@madeye:~$ sudo apt-get install nvidia-kernel-dkms nvidia-xconfig nvidia-settings
Reading package lists... Done
Building dependency tree Reading state information... Done
Package nvidia-kernel-dkms is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or is only available from another source
E: Package 'nvidia-kernel-dkms' has no installation candidate
E: Unable to locate package nvidia-xconfig`
@terdon，我使用了你指出的文章中的这个实用程序：
root@madeye:~# ubuntu-drivers devices | grep recommended
driver : nvidia-331 - distro non-free recommended
然后我安装了 nvidia-331，受限驱动程序实用程序显示它正在被使用。 nvidia GUI 实用程序仍然没有用于配置多个显示器的可见选项（当前有两个显示器连接到该卡），并且我仍然收到错误消息，kern.log称 Nvidia init 模块失败。
仍在努力寻找解决方案......
输出apt-get install nvidia-driver：
root@madeye:~# apt-get install nvidia-driver
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package nvidia-driver is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or is only available from another source`

对于那些来到这里遇到类似问题的人。我的 kubuntu (21.01) 安装无法启动 - 卡在华硕徽标上。 Alt-F2 调出命令提示符，但 dmesg 中唯一的错误是重复：EDAC skx: ECC is disabled on imc 0
按照上面的建议，我使用了：
ubuntu-drivers devices | grep recommended
从推荐的驱动程序中，我安装了：
sudo apt-get install nvidia-driver-470
重启后，一切正常。快乐的时光。 ECC 错误仍然存在，但我会抑制它们。
