Issue has been duplicated on a mirror machine with the same hardware/software. On that machine I have only the default nvidia /etc/X11/xorg.conf:
$ cat xorg.conf
Section "Screen" Identifier "Default Screen" DefaultDepth 24 Option "AddARGBGLXVisuals" "True" EndSection
Section "Module" Load "glx" EndSection
Section "Device" Identifier "Default Device" Driver "nvidia" Option "NoLogo" "True" EndSection
