We are working on better documentation for this, but the main highlights
are: In most cases graphics/drm-kmod should suffice, especially on
somewhat modern hardware. You can also install any of the drm-*-kmod
ports directly, if you want a specific version. In general graphics
hardware older than from 2013 requires drm-legacy-kmod instead.
drm-kmod will also install drm-legacy-kmod on i386.
The same drivers in drm-legacy-kmod is also available in base on 12, so
you can use the base drivers. This is deprecated however, and not the
case for 13-CURRENT.
You can install the drivers either from pkg, if you are using the
GENERIC kernel, or build from ports if you have a customized kernel or
if you are tracking for instance 12-STABLE or 13-CURRENT.
If you are using drm-legacy-kmod or the base driver with AMD graphics
cards you might also need to install xf86-video-ati-legacy rather than
xf86-video-ati.
