This PR addresses persistent and widely reported suspend/resume failures and desktop freezes experienced by users running Omarchy with NVIDIA GPUs in the default Hyprland (Wayland) environment. The fix required integrating a combination of three critical, validated configuration changes to ensure the GPU state is correctly saved and restored during system sleep. 1. Driver Configuration (install/config/hardware/nvidia.sh): - Correct UKI Rebuild Command: Replaces 'sudo mkinitcpio -P' with 'sudo limine-update'. - Modprobe Options: Ensures the essential 'modeset=1' is configured for stability. 2. Kernel Parameter (bin/omarchy-refresh-limine): - Adds the recommended kernel parameter: KERNEL_CMDLINE=mem_sleep_default=deep. This fix was developed and tested successfully against Omarchy running a recent NVIDIA GPU configuration.

There was a problem hiding this comment.
If this is only a fix for nvidia, it needs to be in the install/config/hardware/nvidia.sh script. Otherwise it'll obvious affect all installations.
