# Acer Power Control - Omarchy
|
|
|
|
GPU power and turbo mode setup for Acer Nitro/Predator laptops running [Omarchy](https://omarchy.com).
|
|
|
|
Unlocks the full GPU power range (up to 60W) by enabling the `acer_wmi` predator mode kernel module option, setting the platform profile to performance, and enabling NVIDIA Dynamic Boost via `nvidia-powerd`.
|
|
|
|
## Requirements
|
|
|
|
- **OS**: [Omarchy](https://omarchy.com) (Arch Linux)
|
|
- **Hardware**: Acer Nitro or Predator laptop with NVIDIA dGPU
|
|
- **Kernel**: Must have `CONFIG_ACER_WMI` enabled (default on Arch)
|
|
|
|
## Quick Start
|
|
|
|
```bash
|
|
git clone https://github.com/28allday/Acer-Power-Control-Omarchy.git
|
|
cd Acer-Power-Control-Omarchy
|
|
chmod +x setup-acer-turbo.sh
|
|
./setup-acer-turbo.sh
|
|
```
|
|
|
|
The script will re-run with `sudo` automatically if not run as root.
|
|
|
|
**First run requires a reboot** - the `predator_v4` module option only takes effect after reboot. Run the script again after rebooting to complete setup.
|
|
|
|
## What It Does
|
|
|
|
The script performs four steps:
|
|
|
|
### 1. Configure acer_wmi Module
|
|
|
|
Writes `/etc/modprobe.d/acer-wmi.conf` with `predator_v4=1` to enable turbo power mode support in the Acer WMI kernel module.
|
|
|
|
### 2. Activate Predator Mode
|
|
|
|
Checks `/sys/module/acer_wmi/parameters/predator_v4` to verify the module option is active. If not, prompts for a reboot.
|
|
|
|
### 3. Set Platform Profile to Performance
|
|
|
|
Writes `performance` to `/sys/firmware/acpi/platform_profile`, unlocking higher GPU power states controlled by the laptop's Embedded Controller (EC).
|
|
|
|
### 4. Enable nvidia-powerd
|
|
|
|
Enables and starts `nvidia-powerd.service` for NVIDIA Dynamic Boost, which allows the GPU to dynamically allocate power between the CPU and GPU based on workload.
|
|
|
|
## Usage After Setup
|
|
|
|
After each reboot, press the **Turbo Key** (NitroSense button) on your keyboard to cycle through GPU power levels:
|
|
|
|
```
|
|
35W -> 40W -> 50W -> 60W (max)
|
|
```
|
|
|
|
Press it 3-4 times until you reach the desired power level.
|
|
|
|
### Quick Check
|
|
|
|
```bash
|
|
nvidia-smi -q -d POWER | grep 'Current Power Limit'
|
|
```
|
|
|
|

|
|
| Path | Purpose |
|
|
|------|---------|
|
|
| `/etc/modprobe.d/acer-wmi.conf` | Enables `predator_v4=1` module option |
|
|
| `/sys/firmware/acpi/platform_profile` | Set to `performance` (runtime, not persistent) |
|
|
|
|
## Uninstalling
|
|
|
|
```bash
|
|
# Remove module config
|
|
sudo rm -f /etc/modprobe.d/acer-wmi.conf
|
|
|
|
# Disable nvidia-powerd if desired
|
|
sudo systemctl disable nvidia-powerd
|
|
|
|
# Reboot to restore defaults
|
|
```
