Acer gaming laptop GPU power management setup

[28allday]

Acer gaming laptops (Nitro/Predator) running Omarchy with NVIDIA GPUs are stuck at their lowest GPU power limit unless the acer_wmi kernel module is configured with predator_v4=1. Without this, the Turbo key that cycles through GPU power levels doesn't function, and nvidia-powerd for Dynamic Boost isn't enabled.

The actual power limits vary by laptop model and GPU, but without this configuration every affected Acer laptop is locked to its minimum. This is a significant performance bottleneck that isn't obvious to users — everything appears to work fine, just slowly.
Suggested solution

An optional setup script (e.g. Setup > Hardware > Acer GPU Power) that:

Configures acer_wmi with predator_v4=1 in /etc/modprobe.d/

Sets the platform profile to performance

Enables nvidia-powerd for Dynamic Boost

Prompts for reboot if needed

Shows the current and maximum GPU power limits so users can confirm it worked

After setup, users press the physical Turbo key to cycle through their laptop's available power levels up to its maximum.
Reference implementation

I have a working script that handles all of the above. Happy to adapt it to Omarchy's conventions and submit a PR if there's interest.
