Black Screen after laptop wake from sleep NVIDIA

Closes #4200

Haven't made a PR like this before, in a Distro so forgive me if something is off here! Love what you are all doing with Omarchy this has been a blast using as my daily driver!

Enable full video memory preservation by adding NVreg_PreserveVideoMemoryAllocations=1 and regenerating initramfs for existing NVIDIA machines

which NVIDIA card are you using and what is the version of NVIDIA driver you are using ?
because on nvidia-open and rtx 4070 i dont have this issue on both my pc and laptop , also kargs and NVIDIA module settings are already handled by nvidia-utils on arch Linux and this karg is not needed.

GPU: NVIDIA GeForce RTX 5070 Laptop GPU
Driver Version: 590.48.01
Driver Package: nvidia-open-dkms 590.48.01-1

Maybe Blackwell specific?

This karg fixes my problem though? Maybe I'm missing something?
