在 18.04 中每次内核升级后都缺少 nvidia 模块

Question

每次内核升级后，当我重新启动时，我只会看到一个空白屏幕

看起来专有的 nvidia 内核模块不会自动重新编译

我必须启动到恢复模式并执行

dpkg-reconfigure nvidia-dkms-415

之后一切都很好，直到下一次升级。

我猜系统中有些东西搞砸了，最初我尝试从 nvidia 安装 nvidia 驱动程序，但最终将其删除并只使用了 ubuntu 驱动程序。

任何提示如何整理我的系统？我不想重新安装。

我正在使用这个ppa：

后

sudo apt purge 'nvidia.*'
sudo apt install nvidia-driver-415

Answer 1

你dkms的坏了。我建议以这种方式修复它：

sudo rm -r /var/lib/dkms/nvidia
sudo apt install --reinstall dkms
sudo apt purge 'nvidia.*'
sudo apt install nvidia-driver-415

这将清理 dkms 目录，dkms.conf正确创建和安装驱动程序。
