Bug Description

Binary package hint: gnome-settings-daemon

Ubuntu Release: Maverick 10.10 x64 bit version
gnome-settings-daemon 2.30.2-0ubuntu5
using 2 keyboard layouts: US and Lithuanian Standard

gnome-settings-daemon starts using 100% CPU, keyboard layout starts switching automatically (panel indicator does not show layout change though). For example if US layout key 4 in LT layout is ; character, when i repeat typing 4, i get ;;;44;; (I'm not changing layout during typing)

I can fix problem by killing gnome-settings-daemon, but after several hours it starts using 100% CPU again.

is there any chance to attach gdb to that process and get a backtrace to know what it's doing? probably this is related to bug 625793

BTW, this bug occurs only with "Separate layout for each window" option enabled.

And "Separate layout for each window" option is default in the new Maverick installation? Because i do not remember changing this option.

Yep. Keyboard Preferences → Layouts → Separate layout for each window.

I fixed it by removing all dotfiles in my /home/, so it's probably something changed in the settings format.

In my case(Maverick 10.10, latest updates) I have three layouts(en, ru, uk) and sometimes(once per hour or two) keyboard indicator starts cycling between layouts very fast. It makes impossible to enter any text, so I'd mark this as high importance bug. The gnome-settings-daemon eats a lot of memory(from 100 to 800 Megs from my observation) and use CPU heavily (up to 100% on one processor). Solution is to kill it and restart.
I'll try to disable "Separate layout for each window" option as suggested above and check if it helps.

Disabling "separate layout for each window" didn't help.
A very annoying bug.
The only functional solution I saw so far is to turn off keyboard applet in gconf-editor /apps/gnome_settings_daemon/plugins - so it's not really a solution, just a way not to use this feature (and use alternative kb-layout apps line gxneur).

I confirm... have just the very same problem.
My solution is to kill the process. It leads to disabling of all appearance settings to defaults.
Then I go System-Preferences-Keybord and this process runs again and all the settings come back to their places. (no restart is needed).
I have 3 layouts: ru, en, ukrainian
