PPD 0.13 doesn’t have AMD changes.
That’s a bit weird; it didn’t do the calculation for you it was supposed to.
Anyway: it looks like:
- with 0.21 it consumed 3000 uAh.
- with 0.20 it consumed 5000 uAh.
So to me it looks like 0.21 consumed less.
Thanks for explaining this. I guess the bug was not replicable or it happens randomly. Reading from USBC meter confirmed that the consumption was indeed <1W in all 0.13, 0.20 and 0.21 versions of PPD
The text at issue - the commit message - could be clearer. Here it that text.
Framework provides expansion cards. For the HDMI and DisplayPort, these benefit power management via enabling auto suspend.
I take it that the ‘these’ in the second sentence means ‘these commits’, i.e., these changes.
One wonders when the changes are liable to make it into various Linux distributions. Still, I guess - I have not checked - that the programs tlp and powertop will if suitably configured already give one the power reducations at issue.
Tuned is becoming the default for Fedora 41. Is ppd still the recommended daemon for AMD? If so how should we manually enable it?
The two projects are going in different directions. There are some optimizations ported to tuned but not all.
My personal opinion (and of course I’m biased) is that a collection of python scripts that run at critical boot path for power savings is overkill.
Is there a short reference available for gaben’s second question - how to manually enable/configure ppd on Fedora 41 (without trawling back through the previous years worth of posts in this thread )?
It should just be to use dnf to uninstall tuned and then again to install power-profiles-daemon.
Actually, it seems to force tuned-ppd even if you attempt to install power-profiles-daemon. That’s…not cool.

Wtf? That’s awful. Please file a bug.
I’m trying the discourse route…F41 and power-profiles-daemon - Fedora Discussion …There’s already a discussion about it, sort of: F41 Change Proposal: Make Tuned the Default Power Profile Management Daemon (System-Wide) - #38 by decathorpe - Fedora Discussion Which leads to the bug comments at 2293628 – Make Tuned the Default Power Profile Management Daemon. Quite the curt response.
I tried forcefully installing it from koji. It installs, but all the nice integrations with gnome are busted. Not sure if it’s even doing what it’s supposed to.
I think you should file another bug, that all sounds really wrong.
Maybe after rebooting does everything come back to life with the force install?
I’m wondering what will happen if you uninstall it and install TLP instead? Switch back to ppd when tuned is no longer forced upon users
Mario reported the bug here: 2323331 – Unable to install power-profiles-daemon anymore
Edit: Update for ppd is coming to F41 that should fix the issue.
Thanks for the updates over the weekend, I was away or I would have been more proactive. Thanks @Mario_Limonciello for opening the ticket.
I tested the new version. I was able to switch to ppd, however the profiles don’t seem right and the power/batter switch behavior has regressed.
I cut https://bugzilla.redhat.com/show_bug.cgi?id=2323558 with details.
Ah you’re the one from the issue! I’m not sure what is happening on your system, but the balanced profile has existed for a long time (always?). I’m on KDE so maybe gnome didn’t show it to the user, but the support was definitely there in PPD.
My apologies for this issue. This was caused due to the change to Tuned by default, and was caused due to an oversight by me and the change owners.
It should be fixed soon. Feel free to ping me in the future!
No apologies needed. I’m still not sure why my experience was different on F40, but the balanced profile does what I expect. I appreciate the responses from everyone.
