I've just pushed a new version for TLP to unstable (
tlp=1.0-1.1). This changes several default settings for TLP. These need testing to make sure they don't have any unseen side-effects (though I've been running these myself for the last few months on three systems without issue).
You will have to merge or replace
/etc/default/tlp with the new settings if you have made any changes to that file - check for a
You'll also either have to reboot or reload and restart TLP (
systemctl daemon-reload; systemctl restart tlp) for the changes to take effect.
Please test as best you can (e.g. check
powertop output before and after) and feed back. Please post if you find any changes or you have any issues; please also include your hardware details where relevant.
If you can't see the update yet it will be mirrors - you can download directly from e.g.
Be less aggressive with SATA ALPM to prevent poor SSD performance and potential data corruption.
Use hardware defaults for open-source AMD drivers. This allows demand-based power scaling and can vastly reduce heat generation.
Enable audio power saving on AC power. We don't need to run things constantly at full power.
Enable runtime power management for PCI(e) on AC power. We don't need to run things constantly at full power.
Disable aggressive USB device autosuspend. This prevents "hidden" issues with USB hardware that is incompatible.
Note: this may increase power usage - it remains to be seen what effect it will have. However, IMHO better compatibility with devices (and fewer random issues) makes it better as a default.
