In Section 5.4.5, video cards are listed, but not enough information was given regarding their drivers. https://www.freebsd.org/doc/handbook/x-config.html IMO we should have something similar to this in our handbook to guide users to install the correct drivers: AMD/ATI xf86-video-ati catalyst-libglAUR lib32-catalyst-libglAUR AMD_Catalyst Intel xf86-video-intel mesa lib32-mesa Intel_graphics The full list: https://wiki.archlinux.org/index.php/xorg#Driver_installation
In /etc/make.conf the driver name from x11-drivers/xorg-drivers can be added to the argument OPTIONS_SET= , such as ATI, INTEL, VESA or NV. For instance, /etc/make.conf OPTIONS_SET= ATI INTEL NV VESA OPTIONS_UNSET= AMDGPU This, of course, doesn't cover adding it to documentation.
These are the make.conf arguments: x11-drivers_xorg-drivers_SET= x11-drivers_xorg-drivers_UNSET= Options are: ATI JOYSTICK LIBINPUT VESA, AMDGPU and any other drivers listed in the Makefile The make.conf examples in the other posting work too, but this one is more specific and proper.
