Where would you have expected documentation about this additional step needed?
The instructions at https://wiki.debian.org/NvidiaGraphicsDrivers may have improved since last year, but they do not seem to mention update-glx at all (there is just one mention of glx-alternative-nvidia in the context of nouveau).
Maybe they could also warn about the danger of having a -support package installed without the corresponding driver (especially if the dpkg alternative happens to point to that one), which can easily happen when removing one flavor of the driver.
(I had also looked in /usr/share/doc/nvidia-open-kernel-dkms and /usr/share/doc/nvidia-open-kernel-support but there was no README.Debian)
Maybe installing one flavor of the driver could print a very visible message advertising update-glx if the new flavor is not the selected alternative?
I don't know if the boot scripts could fail more gracefully if they think they should load one flavor of the driver but that is not present on the system.
It would have been nice if removing the driver had automatically switched the alternative choice somehow, possibly by automatically removing the -support package, but the current behavior seems to be by design so people can install the driver manually and still use the -support package.
