This utility can help to gather useful information:

sysutils/hw-probe

A recent probe of my own notebook (with Radeon hardware), but please

In most cases, it should suffice to edit your rc.conf as described at 
<https://www.freshports.org/graphics/drm-fbsd13-kmod/#message>.

If you have not already done so, try installing:

x11-drivers/xf86-video-ati

Exceptionally

% grep -B 1 kld_list /etc/rc.conf
