Description Juha Tiensyrjä 2009-12-23 09:06:22 UTC 
Version:            (using Devel)
OS:                Linux
Installed from:    Compiled sources

I just installed KDE SC 4.4 beta 2 from Kubuntu ppa. After rebooting the computer to use the new environment, I noticed that processes plasma-desktop and kded4 are hogging up the CPU.

I am running Kubuntu 9.10 with the 4.4 beta 2 packages on a Lenovo Thinkpad T61. The display controller is a Nvidia Quadro NVS 140M, and I'm using the Nvidia binary drivers.

After rebooting, only plasma-desktop is eating the CPU.

- Which widgets have you in your Desktop ?
You could backup your Plasma configuration (in can help you with that) and start removing widgets until the CPU usage gets normal, in order to find the culprit

I tried removing widgets from the desktop. Removing them all made no difference, but I noticed that when system tray hides some icons, the CPU use is high, but when I expand the system tray to show all icons tha CPU use drops to almost nothing.

I removed the battery monitor from the system tray (which I had set to be hidden), and that dropped the CPU back to zero. After reinserting the battery monitor the CPU use jumped again.

For now I'll just set the visibility of the battery monitor to auto, which makes the CPU use drop.

I can confirm that. Actually unfolding the systray makes the cpu-usage drop to 5% again. It is clearly related to the battery widget.

That is fixed for KDE SC 4.4.1: bug 226391. Regards
