I've had this issue repeatedly. Here are the apps I typically have open when this occurs: Firefox 14, Gnome Terminal, GEdit. This is running in VirtualBox. Looking at strace and .xsession-errors, I see that gnome- settings-daemon appears to be getting into some sort of infinite loop. Hopefully this will help somebody find and fix the root cause.
The .xsession-errors file simply has the following line over and over: (gnome-settings-daemon:1450): libappindicator-CRITICAL **: app_indicator_set_label: assertion `IS_APP_INDICATOR (self)' failed The strace has the contents of the attached strace.txt file repeated infinitely. ** Attachment added: "strace output" https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/969359/+attachment/3313873/+files/strace.txt -- 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: New Status in “gnome-settings-daemon” package in Ubuntu: Confirmed Status in “gnome-settings-daemon” source package in Precise: Triaged Status in “gnome-settings-daemon” package in Fedora: Unknown Bug description: Check comment 33 for a possible workaround. 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. I am not sure how to restart gnome-settings-daemon, I tried opening a terminal and running gnome-settings-daemon again but this crashes my system - my external monitor switches off and my laptop locks up. I am able to reboot with SysRq+REISUB. Sorry I cannot provide more information - it happens twice now, maybe someone can tell me how to get more information for the next time this happens. $ lsb_release -rd Description: Ubuntu precise (development branch) Release: 12.04 $ apt-cache policy gnome-settings-daemon gnome-settings-daemon: Installed: 3.4.0-0ubuntu2 Candidate: 3.4.0-0ubuntu2 Version table: *** 3.4.0-0ubuntu2 0 500 http://gb.archive.ubuntu.com/ubuntu/ precise/main amd64 Packages 100 /var/lib/dpkg/status ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: gnome-settings-daemon 3.4.0-0ubuntu2 ProcVersionSignature: Ubuntu 3.2.0-20.33-generic 3.2.12 Uname: Linux 3.2.0-20-generic x86_64 ApportVersion: 1.95-0ubuntu1 Architecture: amd64 Date: Fri Mar 30 17:16:02 2012 InstallationMedia: Ubuntu 12.04 LTS "Precise Pangolin" - Beta amd64 (20120301) ProcEnviron: LANGUAGE=en_GB:en TERM=xterm PATH=(custom, user) LANG=en_GB.UTF-8 SHELL=/bin/bash SourcePackage: gnome-settings-daemon UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-settings-daemon/+bug/969359/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
