Just sitting there, with nothing running on a Duel Core machine it chews up 23 to 33% of one CPU. Standard wall paper, nothing fancy going on, no dread dog in the background. Top shows Plasma-Desktop using >25% of one processor to show a static screen.

What the heck is it doing?

Try temporarily disabling compositing/desktop effects (Shift+Alt+F12) and see if that stops it...

No difference. My graphics card probably not capable of much composting anyway, and multiple effects were flagged as not possible. (Its a Vmware guest).

Seems the thing that stops the cpu hogging is to drop to runlevel 3 and back to 5, after first boot. From then on it seems ok.

I suspect there is some part of the start up that is not completed, but I wish there was a way to find out what it was.

If you use htop you can tell it to show individual threads (you probably can with top too but htop is a little easier imho). That might give you a clue as to what process is hanging or hogging the cpu. -- =================================================== Rodney Baker VK5ZTV rodney.baker@iinet.net.au ===================================================
