'pkg which' is your friend (at least sometimes:-) - $ pkg which /boot/modules/i915kms.ko /boot/modules/i915kms.ko was installed by package drm-fbsd12.0-kmod-4.16.g20200221 I believe the recommendation is that you use the graphics/drm-kmod meta-port, in order to get the correct version for your FreeBSD version - and build the port, not install the package, to make sure it is in sync with your kernel. Then add to rc.conf kld_list="/boot/modules/i915kms.ko" - to make sure that the version from the port is the one that is loaded (do *not* list it in loader.conf). --Per Hedelandhome | help
