Hmmm, I have easily around 500-600 wakeups/second. But I do not even see
plasma-desktop in the process list on the Overview tab of powertop.
No, no plasma-desktop there at all. But stuff like KWin, Dolphin, Kmail,
Akregator, some Konquerors which were preloaded - why are these doing
anything anyway? -, sometimes Iceweasel, and various Nepomuk stuff like
nepomukindexer, nepomukservicestubs and virtuoso-t, as well as postgres
for Akonadi, some interrupt threads (I use threadirqs kernel option) and
BTRFS.
Still fan isn´t even running most of the time. Sandybrdige CPU is in C7
sleep state in 87% of the time. It idles in about 30-35% of the time and
is at 800 MHz in about 60% of the time. Rest is distributed among
frequencies with the bulk of 2-8% in turbo mode.
The machine is basically doing nothing except for those wakeups.
Thus is you have plasma-desktop in the first place, I think this is not
normal. Unless you do not run anything else at all in the moment. I think
I will try with all user applications closed and look again.
I would test with a new user with a bog standard KDE configuration first. If
that is better I would disable plasmoids one by one starting with those
which I added yourself until I find the culprit. Since these are running in
the context of plasma-desktop and I am not even sure whether they run as
threads there, I do not know any other approach that would work.
Ciao,
