The crux of the problem is an API mismatch between the kernel module and
the nvidia driver. The problem arises in the normal course of applying
updates and not from user tinkering (see #1).
$ uname -a

$ journalctl -b -k | grep -m 1 -A 3 "API mismatch"
Dec 11 21:07:00 OptiPlex-380 kernel: NVRM: API mismatch: the client has the
version
455.38, but
NVRM: this kernel module has the version
440.100.
Please
NVRM: make sure that this kernel module
and all
NVIDIA driver
NVRM: components have the same version.
$ apt-cache depends linux-modules-nvidia-455-generic

There's no nvidia kernel module for 455 and 5.4.0-47 and hence the
broken system. Boot 5.4.0-54 and everything works. Upgrade[boot]
5.4.0-57 and the system breaks again.
