Sorry, could you provide the resulting powertop.html file?

Censored version of powertop.html

I can confirm this still happening in Fedora 22 with the following packages:

powertop-2.7-5.fc22.x86_64
tuned-utils-2.4.1-5.fc22.noarch

Works for me, please provide output of:
# LANG=C powertop --html

I can't really unplug my computer right now for a few weird reasons but here you have the output anyway, in case it's not relevant:

$ sudo LANG=C powertop --html

It should be named powertop.html.

Thanks, but I am unable to reproduce:

# powertop2tuned -i ./powertop.html powertop

This generated tuned profile from your powertop.html without problem.

Oh! I was missing the -i parameter to specify the input file, can't believe that!

I've tried that now and works perfectly fine for me too, next time I should read the manpage before blindly following some comment in some forum elsewhere, sorry for the noise.

Btw, I believe this bug report is invalid then, since per the bug description I understand the reporter might actually have made the very same mistake than me:

> Steps to Reproduce:

Thanks for your help, I probably wouldn't have noticed otherwise :)

Without the '-i' switch, it should automatically generate the powertop.html to temporary place and use it for input. It should be the same file. Both variants works for me.

You're right again, I was running powertop2tuned powertop.html (after having generated powertop.html manually) which is wrong and, now I realize of it, different from the bug report.

Guess I should leave early today and get some sleep... sorry and thanks again

OK, closing.

The error is reproduced in Fedora 22 with the packages: 
 
 powertop-2.7-5.fc22.x86_64
 tuned-utils-2.5.1-2.fc22


I can generate the tuned profile from the attachment from 'Mario Sanchez Prada', but not with the powertop.html generated on my system.

Could you provide your powertop.html (that one which is failing)?

powertop.html

The html don't have the section : <h2 class="content_title"> Software Settings in Need of Tuning </h2>

I installed Powertop first . Then start the service , following the instructions of Fedora Magazine :
sudo systemctl start powertop.service

That automatically sets all parameters optimisable of " good."

Then installed powertop2tuned for first time. That is the attachemnt that don't work.

I see later that if i active some tunnable as " Bad " , then it works.

Apologize for the noise .

Yeh, it generates tuning only for items that are marked as 'bad'. Also by default powertop2tuned doesn't enable the tunings (it creates tuned.conf with all tunings commented for safety). By using the -e switch the 'bad' tunings are explicitly enabled in tuned.conf:

# powertop2tuned -e MYPROFILE

Powertop.service and powertop2tuned are two different approaches to the same thing, please do not mix them together. Powertop.service enables all tunings in one shot - user has no control over the process. Powertop2tuned generates tuned profile which allows user to fine tune the settings.
