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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/969359 Title: [keyboard]: gnome-settings-daemon consumes 100% cpu (and blinking numlock) To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-settings-daemon/+bug/969359/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
