Hello Preston, I have had this problem on occassion, but it only appears maybe 3 times. I do a killall kded4 and then krunner -> kded4. That seems to calm it down. I do not understand what it does exactly. http://api.kde.org/4.0-api/kdelibs-apidocs/kded/html/index.html Shura ________________________________ From: Preston C. <gprestonc@xxxxxxxxx> To: General Discusson about Arch Linux <arch-general@xxxxxxxxxxxxx> Sent: Sunday, March 15, 2009 1:53:58 PM Subject: Re: cpu usage very high after update... Thanks for the replies. Bram, I did install KDE and I did restart after updating, although this is the first time I have logged into KDE since the update.. Xavier, that is interesting. It seems to be a problem with KDE 4.2, surely they would have fixed it with KDE 4.2.1? I never have had this problem before when I was using KDE 4.2. In short my CPU usage will not go below around 50% and keeps jumping up to 95%-100% a lot of the time.
