Thanks Andreas

I disabled the backports package source and - voila.

Abort.

Turn backports on again and it also works if I specify backports

# apt-get -t stretch-backports install nvidia-driver

So even though I have such a large priority difference in favour of
stable, apt is somehow preferring libegl1, which comes from backports,
over libegl1-glvnd-nvidia.

Well nevermind, I guess we will try to figure out some preferences
magic to prevent mixing nvidia packages from stable & backports.
If you have some suggestions based on your experience, I would
welcome them.

Otherwise, please close this bug.
Kind regards
