TLDR: Not a TDE problem.
This system has an old Nvidia card. The installation is multiarch.
When upgrading from Jessie to Stretch the primary arch was converted
from nvidia (current) to nvidia-legacy but I forgot to convert a
foreign arch to match. This confused the glx-diversions mechanism
resulting in the omission of one of the five layers of symlinks for
libGL.so.1 for the primary arch. Upon switching the foreign arch
to nvidia-legacy the missing primary arch symlink was created.
