Indagating with system monitor i've discovered is the process "beagled" start eating 2nd core power. Removing it (along with the deskbar) from startup program totally fixes the problem.
I've also found that likely the same bug was reported before for beagled: https://launchpad.net/distros/ubuntu/+source/beagle/+bug/64326 Anyway the bug report states "Fix Released" but the bug is still exists today (my ubuntu system is daily updated). -- 100% cpu load after 5' of inactivity https://launchpad.net/bugs/77106 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
