How could it? It has no way of knowing the context of GPU use (ie. which GPU is wired with primary display), since the devices do not offer such a metadata. This X.org just fails, and very generously informs you of the above notion. Read the handbook: https://www.freebsd.org/doc/handbook/x-config.html To set the Intel=C2=AE driver in a configuration file: Example 5.1. Select Intel=C2=AE Video Driver in a File /usr/local/etc/X11/xorg.conf.d/driver-intel.conf Section "Device" Identifier "Card0" Driver "intel" # BusID "PCI:1:0:0" EndSection If more than one video card is present, the BusID identifier can be uncommented and set to select the desired card. A list of video card bus IDs can be displayed with pciconf -lv | grep -B3 display. Then reboot your computer and whatever, see if it works or not. Still don't work? You might need to configure a primary screen. Because you did not give me the entire X.org log, I cannot know whether X.org figured out a server layout or not. A screen configuration binds a graphics device with a display. It is possible that creating a screen configuration might have X.org use that screen as the primary, and automatically configure a server layout from i= t. Write this crap to file /usr/local/etc/X11/xorg.conf: Section "Screen" Identifier "Screen0" Device "Card0" EndSection You could also declared monitors here, but since we leave them out, X.org will figure out the outputs, rolls 20 sided die to choose some funky resolution and clones the framebuffer on all the outputs that have display physically attached. If the Screen section ain't enough, then we finally we add the following to xorg.conf: Section "ServerLayout" Identifier "Layout0" Screen "Screen0" EndSection This should definitely work, because then X.org finds a server layout in configuration, and thus it will not even try to auto-screw-up a configuration. And this is just for Intel. Don't even get me started on nVidia as slave GPU. That hack is whack I tell you. Got it working on my laptop, though I had to port a few components and create custom automation software for it (some systems programming in ANSI-C and shell scripts). But that was =2E.. years ago. Honestly I am not even interested in nVidia anymore, since the corporation itself is so damn uncooperative with Open Source developers. I just show my finger at nVidia, just like our lord and savior Linus Torvalds. Honestly: This is just the very basics to get started. If you don't have lot of time figuring these out yourself, wait till developers manage to port Radeon KMS drivers from Linux 4.x. Then you can buy a cheap laptop with only ONE Radeon GPU and get X.org working automagically. Until then you gotta be willing to learn how every graphics stack component is configured by hand, and you might wanna learn some systems programming too (ANSI-C and shell scripting for starters).
