Description markuss 2010-03-15 01:29:17 UTC

Version:            (using KDE 4.4.1)
OS:                Linux

After 15 minutes, PowerDevil causes the X process to use 100% of the CPU if I unplug my laptop from the power cord and the replug it.
This bug looks very similar to Bug 174897 -- maybe the same problem reappeared or ít's something different.

I'm not the only one experiencing this, judging by that thread: http://linux.derkeiler.com/Newsgroups/alt.os.linux.suse/2009-01/msg00003.html

My setup:
openSUSE 11.2 with X.Org X Server 1.6.5 using NVidia's proprietary drivers.
Other packages: http://en.opensuse.org/Product_highlights_11.2
KDE SC upgraded to 4.4.1

I also see this with OpenSuSE 11.2 and KDE 4.4.1 and Intel graphics. I think this started with the upgrade to KDE 4.4.0.

This sounds like bug 174897 except that was fixed some time ago.

Workaround: disable the powerdevil service.

Same problem as Stefan here, also openSUSE 11.2, but with KDE 4.4.2.
Disabling powerdevil + logout + relogin is a workaround.
