Description Christian Lohmaier 2011-12-16 23:28:17 CET
Description of problem:
Booting into mageia alpha2, GNOME, the cpu governor is set to performance, causing the fans to kick in after a short while, and unnecessarily draining power.

Even when unplugging AC, when the laptop is running on battery alone, the governor is not changed back to ondemand or powersave.

The default should be the "ondemand" governor that one suits the general use-cases best.
Comment 1 Manuel Hiebel 2011-12-17 13:59:16 CET
In live mode or after tge install ?
Comment 2 Christian Lohmaier 2011-12-17 14:08:25 CET
In live mode - it's still too early for me try take the risk of actually installing it :-)) (my disk is too small to have multiple versions installed)

@ Christian

You don't have a KDE Mga2a2 Live CD at hand to see whether the issue exists there, too? (You can't download a Mga2a Live CD atm, unfortunately)

Hi,

This bug was filed against cauldron, but we do not have cauldron at the moment.

Please report whether this bug is still valid for Mageia 2.

Thanks :)

Cheers,
marja

I can confirm that this bug still exists. I'm using Mageia 2 KDE, 32bit, and on my laptop the cpu governor remains set to ondemand when I plug out the AC adapter.
I was wondering why my battery power drains so fast when I found out this. I don't know how the other powersaving features are tuned, like upower or laptop-mode-tools, but will check it as soon as I can and fill bugreports if required.

Thanks, Ilyés, so we know it wasn't solved in Mga2stable

I'm putting (MGA2) on the whiteboard to show that that has been confirmed. 

We won't come with a new set of Mageia 2 live CD's, so this can only be fixed for Mageia3, therefore version must be cauldron again.

again updating the summary

Comment 8 Ilyés Zoltán 2012-06-09 11:01:56 CEST
OK, but what about fixing for the installed Mageia systems. This bug is present not only on the live CD's, but on my installe system too.
Thanks!

There is an existing bug against Mageia 1 and KDE
 https://bugs.mageia.org/show_bug.cgi?id=1720
and someone confirmed it for KDE 4.8 in the upstream bug report.

Is that one the bug you're having?

Please be aware that there is a conflict between laptop-mode-tools and pm-utils

Comment 11 Christian Lohmaier 2013-06-29 02:38:54 CEST
still a problem with Mageia 3, even on installed system (when installing from dual-arch iso at least)

default governor is performance, until you manually install the cpupower package. (cpupower's config then defaults to ondemand)
Comment 12 Marja Van Waes 2016-04-26 12:02:03 CEST
This bug report hasn't seen any action since before Mga4 release. Is it still valid in current cauldron (or, for traditional installer: with the 6dev1 snapshot, or for live isos with Mga5)?

Comment 13 Christian Lohmaier 2018-10-24 13:18:26 CEST
still an issue with current cauldron (fresh install of mga6, then updated to cauldron).

it is using performance no matter whether running on AC or on battery.

Reporter, is this still the case with M7 or even M8 beta ISO?

I will have to close this bug as OLD. Thank you.

@Kernel people,

I think i have read this above is as designed per current standard?

If so this can be closed.

Comment 16 Christian Lohmaier 2021-01-21 20:16:49 CET
no issue with kernel defaults anymore, those now (5.10 as of mga7) default to schedutil if available, problem is with cpupower package. That selects performance when started and ondemand when stopped. The latter absolutely doesn't make any sense anymore, but that was discussed in https://bugs.mageia.org/show_bug.cgi?id=22270 already (closed as obsolete without solution)

The uptick is that cpupower is not enabled by default anymore…
Comment 17 Aurelien Oudelet 2021-02-19 16:50:36 CET
So closing.

Resolution: (none) => OLD
Status: NEW => RESOLVED
