Like the title says. Suddenly, for no apparent reason KDE jumps to 100% cpu usage. I’ve tried tracking this down and it’s frustrating. Sometimes I have to reboot 2 or 3 times to get it back down.
Any suggestions?
Yes, search the forums - many user have the same problem.
Good luck.
I discovered kded4 was using 50% of my cpu. I killed kded4 and it has behaved properly ever since.

I had the same problem - and cure - but it was with 4.2.0 so not a new
problem with 4.2.1.

I have this issue in both Kde 3.xx and 4.xx - it is present since Opensuse 11.1 and is caused by X. Seems to be related to problems with intel video drivers. Eagerly awaiting a fix.

My card is an ATI Radeon HD 2400 Pro.

I just updated my 4.2.1 installation from the openSuSE repositories and now my 4.2 KDE is at a constant 50% CPU load while doing nothing. Plasma just sits up there and churns doing something. Prior to this, it was usually 3-4% at most. Running AMD X86_64 2GB memory wih NVidia Quadro FX1400 card with latest NVidia binaries. Not sure what did it, the Compiz update or the KDE4Workspace updates. Any leads would be nice.

where are you seeeing that 50% utilization?
what does top show?

That’s propably with a dual core machine. Same thing here…
I have a Lenovo T500 with onboard Intel Graphics and onboard ATI mobility. Switching the graphics doesn’t do anything. And yes, I ran “SAX2 -r”.
Also, I’m using the latest KDE4 packets from the repository.

Have the same!
Dualcore with ati mobility, KDE 4.2.1.
Tried “radeonHD” and “fglrx”, both don’t differ.
In both cases, plasma eats up one CPU…
So it doesn’t seem to be card-dependant?
For me too, every lead would be apreciated…
Kind regards, Florian
I see it in KSysGuard, CPU Utilization Plasmoid. Top actually shows Plasma at 97% CPU utilization. I am running Athlon X2 cpu.
…found out, that on my system the calendar-plasmoid was the reason for CPU hunger.
Cheers, Florian
That’s what i was going to write. If you experience high CPU load, remove all extra plasmoids from the desktop and the panel. Usually it’s some ‘old’ plasmoid that’s causing it.
Ok, thanks, I will try that later when I get home. I was going to mention I am running two different platforms, both Dual Core. My desktop is the AMD Athlon X2 which I have been using longer and that’s where I experience the excess usage by Plasma. The other is my laptop which is running Intel Dual Core, same versions of KDE4.2.1 and also an NVidia binary but it does not experience the excess CPU usage. The difference is the plasmoids in use, I have more in use on the desktop, so that sounds logical. Thanks for the tip, I’ll let you know which one I find causing it.
Yes, same one (calendar plasmoid) was causing the issue on mine, just removed it, and plasma load effect now down to 2-3%. THANKS!
Hi everyone I’ve just been reading your posts and have a similar problem. I recently installed an ATI Radeon HD 2400 Pro (AGP) into my machine. I used Yast to install the correct driver and every thing seemed ok, run glxgears etc. Any way every time I try to add a widget to the desktop the whole computer slows down and the Add Widget box locks up. Top shows plasma sitting at around 80% cpu usage. This also freezes all other widgets on my desktop. I must press ctrl-F2 and type logout to reset the problem. Also when I log in it takes much longer to get to the desktop, once it loads everything is fine using desktop effects or not.
It was the calendar in my case, too.
Ok, there are no extra-plasmoids, nothing. Clean desktop. kded4 usage is 68-80%.
Should I remove all plasmoids? 
OK after a reboot.
Hi I updated all packages (KDE4) to the most recent versions and my problem has been partially fixed. However my system is still very sluggish and very strangely stopping ALSA actually improves things!? Anyway my real problem remains that any kind of scrolling in a window causes Xorg to eat up my cpu. My dad has a dual core machine and it runs fine, but when I check with top his system does the same thing but you don’t notice because its dual core. So I’ve built a quad core machine based on a AMD Phemon II the mobo has a built in radeon HD 3300, I’m using the ati drivers installed from Yast (radeonhd). It all works like a dream, however open up top in a terminal and scroll up and down a web site in Konqueror, I see Xorg hitting 47% cpu, konqueror hitting 41% and npviewer.bin sitting at 10% (this is while scrolling at full screen. So it seems perhaps my old single core P4 was just getting overloaded. But then again that much cpu usage seems very odd to me. Any thoughts?
