Comment 37 for bug 449196

I am getting this exact same problem, everywhere I googled, people said that Xorg is a server and it depends on the other programs if it's using too much cpu. In my case, i found out that if I mute the sound as soon as I start linux, Xorg keeps it's cpu usage under 5%.

Maybe it's not big help, but this could be usefull to pinpoint the problem.

Is there any way I can see what programs are sending "things" to Xorg?
