I use a two days old kde SVN build. Xorg takes 100% cpu when idle for more than two minutes. If I move the mouse or press a key, it goes away. Also, if I disable powerdevil service, Xorg doesn't hog the cpu anymore. I'm not sure when this started happening - maybe since a couple of weeks. 

I tried fiddling with the powerdevil options and profile, but I couldn't get rid of this problem; it always happens after 2 minutes.

I'm running kubuntu 8.10 and xserver-xorg 7.4.

Here's more info, just in case it helps:

Kded output when I restart the powerdevil service:

This is the profile that I I'm using:

Please let me know if there's anyway I can help debug this.
