I can confirm this bug also, custom machine, AMD 64, Ubuntu 12.04 LTS x64 fully up to date (this was upgrade from 11.04), ATI video card with FGLRX driver from additional drivers (not post release). I have been trying to pin down the cause for 3 weeks. It appears to be triggered somewhere after (not immediately) when the screen saver or power settings puts monitor to sleep (issue sometimes happening after lunch, but usually happens over night). I have tried both built in blanking and xscreensaver same result. Disabling the power settings and screen savers/blanking prevents the problem from happening. The issues I see are number lock flashing, gnome-settings-daemon using 100% CPU, and constant drive activity. Killing the process does nothing as it is respawned and problem continues. heavy disk activity is caused by ~/.xsession-errors being continuously filled with:
(gnome-settings-daemon:15439): libappindicator-CRITICAL **: app_indicator_set_label: assertion `IS_APP_INDICATOR (self)' failed this issues makes machine near-unusable. Logging out (or killing X with Alt+SysReq+K) and logging back in stops the problem. I am about to try the suggestion in comment #33 as I do not need multiple keyboard layouts (but few of my customers do so this is not fix for them) This does not happen every day, but it does appear to happen more often when I have my video card doing hashing calculations overnight (mining for bitcoins). I am not sure how the video relates to keyboard layout/this issue, but they appear connected somehow -- 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
