No devices detected, no screens found - GeForce 9500M in FreeBSD 12. v1 -- 2

HI, I have an old ASUS laptop M50Ssereis, and I had once successfully started up xfce4 with the using Nvidia GeForce 9500M graphic card before, but I messed it up, and then I couldn't get it working any more after the reinstallation of the freebsd 12. I have installed nvidia-driver modules from the ports.

Please note, without /etc/X11/[login to view URL] and /usr/local/etc/X11/xorg.conf.d/[login to view URL], xfce4 can start up, but without using the 9500M features, so the X screen is very rough. To make this work to complete, the startx startup need to finished with using the GeForce 9500M device.
