not sure about the specific, but adding "us" is something gnome- settings-daemon is doing to solve the issue of "standard keybinding should work across keymaps"
the way GTK does it, is that looks through other configured keymaps if the key combinaison exists (e.g if you use u.s and chinese layouts and activate chinese, you want ctrl-C to keep working, for that to work we need "us" to be actively configured as well) see https://git.gnome.org/browse/gnome-settings- daemon/tree/plugins/keyboard/gsd-keyboard-manager.c#n750 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1225514 Title: adding keyboard layouts no longer seems to update xkb correctly Status in “gnome-control-center” package in Ubuntu: New Bug description: I'm not sure if this is caused by gnome-control-center, or ibus 1.5, but in saucy, adding or modifying the keyboard layouts doesn't seem to properly update xkb any longer. For example, I can have both French (Canada) and English (US) configured, but xkl_config_rec_get_from_server() will only return 'ca' and xkl_engine_get_num_groups() will return 1, instead of 2. I believe this is also causing the keyboard layouts to not appear on the login screen.
