Thread: KDE 4.2.1 sudden 100% cpu usage

    Default KDE 4.2.1 sudden 100% cpu usage

    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?

    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.

    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.

    Cheers,

    Thorsten

    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
