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. Regards -- Niclas Zeising
