Hello.

This happens because the port x11/nvidia-driver renames the OpenGL
library and X11 module installed by Xorg and installs the NVidia ones.
When it's deinstalled, it removes the files and renames back the Xorg
files.

The problem is that when you update the Xorg port (x11/xorg-libraries)
you force its deinstallation, so it removes the NVidia OpenGL libraries
and X11 module (without removing NVidia drivers first) and replaces it
with the Xorg one (without installing NVidia drivers after).

The crash happens because of the nvidia.ko kernel module, that expects
you are using the NVidia OpenGL libraries and X11 module.

So just reinstall nvidia-driver driver after upgrading xorg-libraries
as you were doing so far. Alternatively you could remove nvidia-driver,
update xorg-libraries and install nvidia-driver after that.

Best Regards,
Ale
