如何修复 modprobe 后未找到 nvidia-current？

我在 i386 系统上使用 Debian 10 (Buster) 和 NVidia GT630 显卡。 apt install nvidia-driver安装了 nvidia-legacy-390xx 驱动程序。遗憾的是内核模块未加载（/var/log/Xorg.log 的输出）：

[   100.857] (II) LoadModule: "nvidia"
[   100.858] (WW) Warning, couldn't open module nvidia
[   100.858] (EE) Failed to load module "nvidia" (module does not exist, 0)
[   100.858] (EE) No drivers available.

/lib/modules/4.19.0-12-686-pae/updates/dkms包含三个 nvidia-legacy-390xx*.ko 文件。

dkms status声称已安装 nvidia 模块。 modprobe nvidia想要加载 nvidia-current，但失败了（见下面的日志）。不确定这是否不应该读取 nvidia-legacy？

任何帮助将非常感激。

有关 nvidia-persistenced 的 syslog 输出

Nov 25 12:42:40 htpc nvidia-persistenced: Started (7377)
Nov 25 12:42:40 htpc nvidia-persistenced: Failed to open libnvidia-cfg.so.1: libnvidia-cfg.so.1: cannot open shared object file: No such file or directory

中存在指向 libnvidia-cfg.so.390.138 的 libnvidia-cfg.so.1 符号链接/usr/lib/i386-linux-gnu/nvidia/legacy-390xx。 中不存在此类符号链接和文件/usr/lib/i386-linux-gnu/nvidia/current。

我能够解决这个问题：无论出于什么原因，apt install nvidia-driver安装了 Nvidia 390.132 和 418.152 驱动程序的混合体（可能与 418.152 所需的 nvidia-kernel-dkms 仅适用于 amd64 而不适用于 i386 有关）。

运行apt purge *nvidia* && apt install nvidia-legacy-390xx-driver使我的 X 系统恢复了。
