Hi Sorry by delay.About my kded4, as i told, i turned off all modules, and closed all possible apps.
After some other tests (and reboots), i opened my konsole and started to kill all pids of kded4.
I really haven't idea why, but after some 3 or 4 times killing its, all returned to normal (cpu ~15% with all my apps in use).
Thanks for all, Claudio Em 02-02-2011 14:25, Magnus Berg escreveu:
Use KDE's System Guard to see which process is using such much power. It can be inpossible to see some processes with "top" or "proc". I had problems before with strange processes then I run Aptitude as root. And I couldn't see them in "top" or "proc". Now I run all root activites with sudo. No more problems.
