The upcoming release of Ubuntu 24.04 LTS (Long Term Support) is set to offer a significant enhancement in energy efficiency, specially targeting laptop users. Canonical, the developers behind Ubuntu, are focusing on optimizing the latest iteration of their popular Linux distribution to extend battery life for those using laptops with recent Intel or AMD components.
Ubuntu 24.04 LTS will introduce an updated Power Profiles Daemon, which is a critical component in managing power settings and battery profiles directly from the desktop environment’s quick settings panel. This allows users to easily switch between different power management modes depending on their current needs.
One of the key improvements is the refinement of the “Balanced” power option provided by the power-profiles-daemon package. The update makes this mode more sensitive to the battery’s state, encouraging power-saving measures when the laptop is not plugged into a power source. Notably, with this release, the Power Profiles Daemon will enable AMD and Intel P-State drivers to adopt the ‘balance_power’ Energy Performance Preference (EPP) profile, enhancing energy efficiency. For Intel drivers, the update also adjusts the energy performance bias setting, which contributes to conserving battery power.
The ‘powerprofilectl’ command line tool, which accompanies the Power Profiles Daemon, has seen some updates as well. Bug fixes and a new manual page have been added, assuming the ‘python3-argparse’ package is installed on the system. For those delving deeper into power management, additional debugging options are now available in this tool, aiding in diagnostics and configuration.
An interesting development, as reported, is that laptops running Ubuntu 24.04 LTS will automatically switch to a ‘balance_performance’ profile when connected to a charger. This behavior ensures optimal performance while the device is being powered externally and then switches to a more power-efficient ‘balance_power’ profile when on battery power. This new arrangement expands the power profile choices to a total of four, allowing users comprehensive control over their laptop’s power management.
These advancements present a compelling case for users on previous Ubuntu versions to consider upgrading to Ubuntu 24.04 LTS for not only enhanced performance and features but also for improved energy efficiency. With a launch date set for April 25, 2024, users won’t have to wait too long to experience these improvements firsthand.
Updates like these reflect the continued dedication to evolving the user experience on Linux-based systems, making them more competitive with proprietary operating systems, especially in the realm of portable computing. Combined with the robust community support and the long-term stability that LTS versions provide, Ubuntu 24.04 LTS is shaping up to be an essential upgrade for both current Linux enthusiasts and potential converts seeking a reliable, power-conscious operating system for their laptops.
