This is a continuing problem for me too. Every restart I have to reschedule gnome-settings-daemon to "idle" or it grinds my system to a halt on start-up for minutes on end.
In-case it helps someone else, I do the following: $ ps -A|grep gnome-settings-daemon - This will give you it's PID $ ionice -c3 -p 1234 - Substitute 1234 for your PID - Schedules the process 1234 to "idle" (lowest I/O priority) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/573415 Title: g-s-d uses high disk i/o -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
