Just a note that I am seeing this problem as well, here on an AMD 8350 8-core system using Trusty 14.04 AMD64. The Xorg process takes about 20%-35% of one core, when the system is otherwise idle. I'm open to suggestions regarding how I can dig deeper to determine the cause, because obviously killing the Xorg process isn't an option (or I wouldn't be running it in the first place). As an experiment, to see if it would help to restart X, I did try killing the process then logging back in with the new Xorg process, but the CPU usage was the same as it was before.
Any suggestions are welcome, and I am willing to help debug this.
