# The proprietary NVIDIA driver does early KMS itself: nvidia.conf (written by
# install/hardware/nvidia.sh, sourced before this file) early-loads nvidia_drm
# with modeset=1. Keeping the kms hook on such a system makes autodetect pull
# in nouveau — and ~100 MB of its GSP firmware — for a driver that never runs.
# Drop kms only when nvidia_drm is early-loaded and NVIDIA owns every display
# controller. Hybrid systems keep kms: their iGPU still needs it for early
# KMS at the LUKS prompt. So does anything unexpected, like a PCI tree that
# cannot be read.
#
# This reads MODULES midway through mkinitcpio's drop-in sourcing, so a
# later-sorting drop-in that resets MODULES outright — surface_device_modules.conf
# does — would strip nvidia_drm after kms was already dropped. Every machine
# Omarchy writes such a file for carries an Intel iGPU, which keeps kms here
# through the scan below; keep it that way.
