Description John L. ten Wolde 2017-09-27 00:18:14 CEST
Description of problem:

Occasionally, when logging into Plasma5 on Mageia 6, PowerDevil fails to initialize and KDE's Power Management services are rendered inoperative (i.e. no battery icon on the system tray and opening the respective component in System Settings presents a nasty error message).

I couldn't verify one way or another if upstream is even aware of this issue or not, but the folks over at NixOS certainly are and their Thomas Tuegel offers the following simple workaround:

"One way to mitigate this temporarily would be to disable session saving. In System Settings > Startup and Shutdown > Desktop Session choose Start with an empty session under On Login"

I've been using it for several days now, and it does seem to do the trick.

To read the full NixOS bug discussion and analysis see here:

https://github.com/NixOS/nixpkgs/issues/24563



Version-Release number of selected component (if applicable):

libpowerdevilcore2-5.8.7-1.mga6.i586.rpm
lib64powerdevilcore2-5.8.7-1.mga6.x86_64.rpm
and/or the rest of the powerdevil family...


How reproducible:

The bug is sporadic.

Assuming it's an upstream issue, then.

Thanks for the workaround!

Do this problem still occur without the workaround? ( = with session saving )
If still, it would be interesting to see if Plasma 5.12 now in QA fixes it.
If not OK in Plasma5.12 maybe it should be put in errata.

I'm still seeing it with my HP 6550b laptop. (first generation i3, 8GB, Intel graphics, Intel wifi) 

Just this morning, in fact. There's been nothing that I can see that's different with the boots where it doesn't work, and I'm not clear on when it started. However, hazy memory is that it started with one of the 4.14 kernels. Something related to Spectre/Meltdown mitigation, perhaps?

I just checked, and as I thought, I've had the workaround in place for months. Apparently, it no longer, um, works around on this hardware.
Comment 5 Aurelien Oudelet 2020-08-16 17:54:49 CEST
Mageia 6 changed to end-of-life (EOL) status on 2019-09-30. It is no longer 
maintained, which means that it will not receive any further security or bug 
fix updates.

Package Maintainer: If you wish for this bug to remain open because you plan 
to fix it in a currently maintained version, simply change the 'version' to 
a later Mageia version.

Bug Reporter: Thank you for reporting this issue and we are sorry that we 
weren't able to fix it before Mageia 6's end of life. If you are able to 
reproduce it against a later version of Mageia, you are encouraged to click 
on "Version" and change it against that version of Mageia.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a more recent
Mageia release includes newer upstream software that fixes bugs or makes them
obsolete.

If you would like to help fixing bugs in the future, don't hesitate to join the
packager team via our mentoring program [1] or join the teams that fit you 
most [2].
