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 Ubuntu Desktop Bugs, 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) To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-settings-daemon/+bug/969359/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
