Hello Friends, My PC a 1,9Ghz P4 700MB ram 60 gig Segate Barracuda. running FC2 with kernel 2.6.5-1.358 and the 5336 Nvidia driver. Bla Bla bla... For some reason this week only it has decided that every now and then it will be slow. So I ran top as root and found X using 97% cpu by itself. so I renice it to 15 (Ha ha :=}) But the question is why? in the first place. How can I find out what is causing this, given the only thing that was running was xmms, when I closed it X caried on chomping my cpu! So now I have just reniced it to 19 so that I could finish my mail to you.
