I experienced CPU strange behavior after installing Ubuntu 14.04, at 5 or 10 minutes, CPU usage suddenly increased about 50%, that's really slow my laptop down (Ubuntu 13.10 worked fine by the way)
Here is my laptop specs :
Intel Core i3-2330M 2.20 GHz
4 GB of RAM
I noticed this when the first installation, even after I disabled online and file search, even after I switch to GNOME 3, and even after I used GNOME Fallback Session, how to solve this?
