Cant figure Xorg Configure on Nvidia optimus and Bios Legacy on FreeBSD

I have a difficult thing to set up Xorg on my laptop nvidia optimus, * Allienware M11x R3 * Intel i7-4xxx * Nvidia gt 540M and intel driver * Ram 8 GB When i install Xorg on Freebsd and startx, it failed. I tried to create specific driver to enable just one driver because my laptop cant run both driver on Freebsd. I tried all driver Vesa, Sfcb, and Intel and Nvidia on /etc/X11/xorg.conf.d/driver-vesa.conf, or intel-driver.conf or nvidia-driver.conf. But it cant load and get same error. I tried to figure out to run X -configure and tried startx, again it is still same. When i tun TrueOS it works when i run X -configure then startx And the error outputs on freebsd when I run startx without X -configure are [here](https://pastebin.com/P8APnSn5)
