I think this is one of the mandatory programs for the flexibility of setting up a GUI-based power processor: easy, simple, and straightforward -- of course, its proper use requires a little research for a complete and clear understanding; There are other applications, but they are automated and/or less flexible. The last version of this app (1.0.0-1_all.deb OR 1.0.0-1_all_linux_mint.deb, release 2022-23: https://github.com/vagnum08/cpupower-gui/releases/tag/v1.0.0, with dependencies already in Mint 22) has included the creation of flexible User Profiles to suit needs (between power efficiency and performance effectiveness) with its automation settings on reboot. Unfortunately the last version has not been included in the official repo, hopefully it can be updated soon. Hopefully this application in the future can continue to be improved, equipped with important features, tidied up, while remaining lightweight ~ agile ~ smooth ~ effective ~ efficient; In short, it is a pro and reliable tool. Thanks to Dev and Team. ❤️
