That's the one from xserver-xorg-core
(dpkg -S /usr/lib/xorg/modules/extensions/libglx.so)
Try
  debsums -c xserver-xorg-core
to see whether this has been replaced by using the .run installer.

The 415.xx driver does no longer have a replacement libglx.so, so it
should be fine to load the original one.

But from your xorg.log.old I conclude that it did not even attempt to
load the nvidia driver ... was the kernel module loaded after booting
with the 415.xx driver?
You could try this minimal /etc/X11/xorg.conf:

        Section "Device"
            Identifier     "My GPU"
            Driver         "nvidia"
        EndSection
