	This looks like your video card is being driven in VESA mode, you
should probably (AMD or Intel video) install the drm-kmod package and set up
the appropriate kld_list line in /etc/rc.conf (see the package message for
details tl;dr one of "amdgpu", "i915kms" or "radeonkms" depending on
chipset). It's been a while since I've had any nVidia hardware so I'll defer
to others on that.
