Tuned-PPD Customizer Script Usage Guide

Important consideration

Out of the box, by default, Fedora 41 power settings are excellent. However, for those who want more control over their power performance, this script provides a helping hand while remaining with the existing GNOME power profile menu.

What Does This Script Do?

This script helps you customize how your Fedora install manages power and performance through GNOME's power menu. It lets you change which power management profiles are used when you select "Power Saver" or "Performance" in the GNOME power menu.

This script is part of the Fedora Battery Life optimization page.

How It Works

1. GNOME Power Menu: The menu in your system tray that lets you choose between power modes.
2. The Configuration File (/etc/tuned/ppd.conf): Stores your power profile settings.
3. tuned-ppd.service: Fedora's service that applies these settings when you change power modes.

What You Can Do With This Script

• Back up your current power settings.
• Download additional power management profiles.
• Change which profile is used for "Power Saver" mode.
• Change which profile is used for "Performance" mode.
• View your current configuration.
• Restore previous settings from backup.

IMPORTANT: Run options 1, 2 and then you can run option 4 to apply a new profile. Use the guidance below to select the right one for your powersaver and performance settings.

Using the Script

Install Curl

Curl should already be installed, but just in case:

Fedora

sudo dnf install curl -y

     

To Install Tuned-PPD Customizer Script, simply run:

curl -s https://raw.githubusercontent.com/FrameworkComputer/linux-docs/refs/heads/main/Tuned-PPD-Customizer-Script/tuned-ppd.sh -o tuned-ppd.sh && clear && bash tuned-ppd.sh

     

1. Run the script after later on, from your home directory:

   bash tuned-ppd.sh

2. Choose from the menu options to:

   • Back up your settings.
   • Apply a different profile.
   • View current settings.
   • Restore previous settings.

Available Profiles

Power Saving Profiles

1. balanced-battery

   • Balances performance and power consumption.
   • Uses CPU frequency scaling to reduce power usage while maintaining reasonable performance.

2. cpu-partitioning-powersave

   • Optimizes power consumption for multi-core systems.
   • Uses CPU frequency scaling and core parking.

3. desktop-powersave

   • Prioritizes power saving for desktop systems.
   • Reduces CPU frequency, dims display, powers down idle devices.

4. laptop-ac-powersave

   • Balances performance and power for AC-powered laptops.
   • Uses moderate power-saving techniques.

5. laptop-battery-powersave

   • Maximizes battery life.
   • Uses aggressive power-saving measures.

6. powersave

   • Prioritizes power saving above all else.
   • Uses maximum power-saving techniques.

7. server-powersave

   • Optimizes server power consumption.
   • Balances server performance with energy efficiency.

Performance Profiles

1. accelerator-performance

   • Optimizes systems with hardware accelerators (GPUs/FPGAs).
   • Prioritizes accelerator resource allocation.

2. enterprise-storage

   • Optimizes enterprise storage system performance.
   • Tunes disk scheduling and I/O operations.

3. latency-performance

   • Minimizes system latency.
   • Optimizes for low response times.

4. network-latency

   • Reduces network latency.
   • Optimizes network settings for minimal delay.

5. network-throughput

   • Maximizes network throughput.
   • Optimizes for high data transfer rates.

6. throughput-performance

   • Maximizes system throughput.
   • Optimizes for high data processing rates.

Recommendations

For Laptops: Maximum Battery Life

Best profile: laptop-battery-powersave

• Optimized specifically for laptop battery operation.
• Aggressively reduces power consumption.
• Manages CPU frequency, screen brightness, and device power states.
• Best choice when you need to maximize battery life.

For Gaming: Maximum Performance

Best profile: latency-performance

• Minimizes system latency.
• Keeps CPU at maximum frequency.
• Optimizes for quick system response.
• Ideal for games where every millisecond counts.

For High Computational Tasks

Best profile: accelerator-performance

• Optimized for GPU and accelerator-heavy workloads, or just general high performance non-specific tasks.
• Ideal for video editing and machine learning tasks.
• Prioritizes accelerator and computational performance.
• Best choice when using CUDA, OpenCL, or similar GPU compute tasks.

Troubleshooting

You are using tuned-ppd, not PPD or tuneD itself. Fedora 41 by default, is already using tuned-ppd.

If you see the error Error: /etc/tuned/ppd.conf does not exist!:

1. Verify the configuration file:

   cat /etc/tuned/ppd.conf

2. If missing, either:

   • Create the file manually
   • Reinstall the tuned package

3. Contact support before making additional changes if issues persist

Important Notes and FAQ

• The script is designed for Fedora installations, should work on any distro with tuned-ppd running though with some minor tweaks.
• We get the additional profiles from https://github.com/redhat-performance/tuned/
• Changes take effect immediately after applying a new profile.
• Always keep a backup of your settings using this script.
• These recommendations are based on typical use cases; your specific needs may vary.
• The script clears the terminal screen between sections for better readability.
• Why are is this using bsdtar vs something else? It's been shown to be more reliable for this script. For Fedora users, it self-installs.
• For enhanced control, consider using the TunedSwitcher Flatpak (compatible with GNOME/KDE).
• Ubuntu support is planned for future releases.
