Ubuntu – Is this CPU usage normal for Xorg

compizcpu loadxorg

I checked System Monitor to see if the frequency of my CPU increases without doing anything and saw that xorg is always using 10-40% of the CPU even if it's not doing much of anything on the desktop or simply surfing the Internet. Is this normal? If not, how can I fix it?

I have:

  • a Macbook white 4,1
  • Core2 Duo running at 2.10 GHz
  • GPU Intel GMA X3100
  • 4GB of RAM
  • Ubuntu 11.04

I am running Unity and I do not have many effects enabled. I have only activated Compiz animations, scale, desktop, some shadows…

Actually, the System Monitor itself is a rather graphics intensive application, which makes your claim of not doing anything slightly odd. Try running 'top' instead, but ultimately, xorg will probably use less cpu if compiz is off.
