I am setting up CentOS 7 on my new firewall. This will run as a head- less system, accessed via a serial console when necessary. It's only a 2GB system, so I don't see any reason to have the GPU consuming any of the RAM.

I've blacklisted the i915, drm, and drm_kms_helper modules and rebuilt the initramfs, but the i915 module is still being loaded.

Anyone know what might be loading the module and how I can stop it?

TIA!
