Version: unspecified (using KDE 4.5.0) OS: Linux Disk drive settings like acoustic management or spindown time are somehow being reset when KDE starts up. Reproducible: Always Steps to Reproduce: 1. hdparm -M /dev/sda # get current setting, 0 for me 2. hdparm -M 128 /dev/sda # change to most quiet mode 3. log into KDE Actual Results: hdparm -M /dev/sda again gives 0 Expected Results: hdparm -M /dev/sda should return 128 Other settings are also affected. I set the spindown time in /etc/init.d/hdparm, but when loging into KDE, I have to start the script again to make any of its settings work. I also like some drives to spin down immeadiately after bootup, but they all spin up during login, even if no partitions are mounted.
I doubt that KDE changes any "hdparm" settings, but reassigning for further clarification and for the spin-up issue.
Yeah, I was surprised, too. I had written about my drives spinning up on the gentoo-user mailing list, and someone else showed me this thread: http://thread.gmane.org/gmane.linux.gentoo.user/232044 I confirmed the hdparm -M stuff and so reported the bug here. Could this be Gentoo-specific somehow?
Well, it's definitely not coming from solid, we don't touch hdparm at all in there... Sounds like something gentoo specific indeed (I'm not aware of anything playing with hdparm in the KDE Workspaces...).
Okay, so if it can't be reproduced on a non-gentoo system, I will report this on bugs.gentoo.org then. Sorry for the noise.
Just for the record, the solution is this comment from http://bugs.gentoo.org/show_bug.cgi?id=334393: I had another pm related issue with KDE and it was caused by pm-utils (used by powerdevil). pm-utils sets a lot of pm settings (see /usr/lib/pm-utils/* scripts). Try to disable the harddrive features of pm-utils by: touch /etc/pm/power.d/harddrive and restart KDE.
