I just tried to check this, but powertop 2.13 no longer provides this kind of information. I also found a machine that still has a spinning hard drive. I can hear that the drive goes into standby and is woken up again immediately thereafter. Without a tool to analyse which program is responsible, I do not think we stand a chance to improve this. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/546724 Title: KDE processes writing to icon-cache files "prevents the disk from going to powersave mode."

There is a bug in qpixmapcache (or qpc is used with a different scope). qpc evicts entries from the cache after some time, even if the items are in use, when the set of items is stable (e.g., you only use the same 3 pixmaps all the time). I am currently working on a new implementation for qpc which does not show this behaviour.

The implementation of the icon cache has shifted over to KSharedDataCache in the meantime. Perhaps the best route is to add an internal (i.e. not part of the public API) option to KSharedDataCache::find() to not update the use count on access (similar to noatime in mount) and then have KShare

[Bug 546724] Re: KDE processes writing to icon-cache files "prevents the disk from going to powersave mode."
Hi there! Thanks for reporting this bug! Your bug seems to be a problem with the KDE program itself, and not with our KDE packages. While we appreciate your issue, it would be better if it was tracked at https://bugs.kde.org, so that the KDE developers can deal with this speedily and have direct communication with you as the reporter for more effective debugging.
