CAPS LOCK as keyboard switch indicator does not change status during login time

[George Shuklin]

When CAPS LOCK key is used to switch keyboard layout, CAPS LOCK indicator is usually displays the switch status (in case of bi-language keyboard this is simply English/Other_language idicator).

During login time (via unity-greeter/lightdm) caps is working fine (switching language) but shows no indication of used language, wich cause many useless attempts to enter login in wrong language.

Steps to reproduce:

1) Add additional language to system (in my case it was Russian)
2) Set up CAPS LOCK as keyboard layout switcher
3) Log off
4) Switch language by pressing CAPS LOCK

Expected:
a) input layout switched to other language (in my case Russian)
b) CAPS LOCK keyboard indicator is lighten up

Actual:
a) input layout switched to other language
b) NO caps lock indication

This problem is substantial, because default login window have no idication of current layout and no input field with visible input (password is shadowed by '*' signs). so user have no idea which language is active.

I'd like to point to microsoft windows logon screen, where language is clearly displayed nearly input field to solve this uncertainty.

Status changed to 'Confirmed' because the bug affects multiple users.

Just updated to 16.04 LTS. It seems that greeter crashes and restarts when Capslock is pressed to switch languages and the languages doesn't change. This makes it impossible to login if keyboard layout indicator in menu bar is disabled.

Correction: when greeter crashes the language of input does change, but the indicator doesn't show the change.
