I'm troubleshooting a solution for Nvidia screen tearing cited on the Archlinux wiki which instructs to enable DRM kernel mode setting:

nvidia 364.16 adds support for DRM kernel mode setting. To enable this feature, add the nvidia-drm.modeset=1 kernel parameter, and add nvidia, nvidia_modeset, nvidia_uvm and nvidia_drm to your initramfs#MODULES.

I entered the MODULES into mkinitcpio.conf as instructed. Here is the relevant line from my .conf file: MODULES="ext4 dm_mod dm_crypt vfat nvidia nvidia_modeset nvidia_uvm nvidia_drm"

Troubleshooting, I discovered evidence the modules are not loaded:

$ rmmod nvidia_drm nvidia_modeset nvidia
rmmod: ERROR: Module nvidia_drm is not currently loaded
rmmod: ERROR: Module nvidia_modeset is not currently loaded

I know mkinitcpio HOOKS go in order (ie. LUKS). Is the order of NVIDIA kernel modules in mkinitcpio important?

I think that your syntax is wrong.

The MODULES variable is an array, so assigning to it should be done using (...):

MODULES=(ext4 dm_mod dm_crypt vfat nvidia nvidia_modeset nvidia_uvm nvidia_drm)
