I am on 14.04 LTS and using Gnome. I encountered severe and frequent high CPU consumption caused by gnome-settings-daemon process. I then deleted /usr/lib/gnome-settings-daemon-3.0/keyboard.gnome-settings- plugin. I also applied the num lock fix as explained in #107.
I noticed improved (less frequent) gnome-settings-daemon "hangs," but still experienced them enough to be a big irritant. I then started performing traces. and noticed many failures in trying to open /var/cache/fontconfig. I then googled what could be causing that. I then came across this page: https://bugzilla.redhat.com/show_bug.cgi?id=612105 I then applied (as suggested on that page) restorecon -R '/var/cache/fontconfig' That seems to have done the trick. Everything is quiet now. I will post again if I experience any further problems. Hope this helps someone else! ** Bug watch added: Red Hat Bugzilla #612105 https://bugzilla.redhat.com/show_bug.cgi?id=612105 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/969359 Title: [keyboard]: gnome-settings-daemon consumes 100% cpu (and blinking numlock) Status in Gnome Settings Daemon: Fix Released Status in gnome-settings-daemon package in Ubuntu: Fix Released Status in gnome-settings-daemon source package in Precise: Fix Released Status in gnome-settings-daemon source package in Quantal: Fix Released Status in gnome-settings-daemon package in Fedora: Unknown Bug description: Impact: gnome-settings-daemon uses 100% cpu for ever in some cases Test Case: Seems to happen sometimes after docking or connecting with vnc, try to connect to the machine using a vnc client a few times and check there is no numlock cycle and cpu usage loop starting Regression potential: The numlock state could be wrongly set,restored on login in some cases ----------------- Original message: ----------------- I don't know how to reproduce this bug, but after varying amounts of normal usage of my laptop, I notice gnome-settings-daemon is consuming 100% (approx) CPU.
