Hi

Sorry to hear that. We do need to improve the documentation and
instructions.

What does 'kldstat -v' say? The kernel modules from ports are installed to
/boot/modules and it is common that the old version that comes with the
kernel in /boot/kernel is loaded instead.

There are several ways to make sure that the correct modules are
loaded. I put this in my /boot/loader.conf:

module_path="/boot/modules;/boot/dtb;/boot/overlays"

This will make sure that modules are loaded from /boot/modules first,
and then /boot/kernel if they are not found in the first locations.

To load modules automatically, put in /etc/rc.conf

kld_list="/boot/modules/drm.ko /boot/modules/i915kms.ko"

or simply

kld_list="i915kms"

if you specified module_path.
