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(dpkg -S /usr/lib/xorg/modules/extensions/libglx.so) Try debsums -c xserver-xorg-core to see whether this has been replaced by using the .run installer. > seems to me that it was installed via nvidia-installer.

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 Andreas
