I'm having trouble with kubuntu going unbearably slow, no matter how little I'm doing. I do notice that the CPU usage is stable (usually between 25 and 50%) if I'm not moving the mouse - basically, if I'm just staring at the screen, but when I wiggle the mouse a bit, it rockets up to almost 100%. I'm on a dell laptop, and while I already rolled back the drivers for the onboard graphics (that was another problem, and speed did improve after that), it's still going terribly slow. Does anyone have any idea what might cause this? I've been searching - here and on google - and haven't found anything that might be of help yet.
