Public bug reported: When not doing anything, the system should use close to no cpu ressource.
However gnome-shell is permanantly displaying a cpu usage higher than normal. This happens even even after fresh boot with no application running. Opening applications tends to make the cpu usage of gnome-shell rise abnormally. When nothing is open and I don't touch the mouse, gnome shell takes several percents already. Touching the mouse or having firefox or nautilus open takes on average 30% of one of the cores and rises to 70% with Clementine open. I'm running a fresh amd64 precise install. Actually I installed twice and the problem showed up both times. There was no issue at first. I suspect the proprietary drivers to be involved, though I cannot remember exactly if the problem arose right after their installation. I'm using the latest version of fglrx from amd's website. I think the following threads are about the same problem: http://ubuntuforums.org/showthread.php?t=1980053 http://ubuntuforums.org/showthread.php?t=1966865 Unfortunatly I can't confirm that removing the proprietary drivers solves the problem as the open source ones do not support 3D features for my graphic card yet and I would end up on a fallback session. I'm not accustomed to making bug reports so if their is anything else needed ask away.
