Num lock warning not displayed during log in

[Sarrvesh]

While unlocking ubuntu (after it hibernates or reactivating after screensaver), it prompts for password. Previous versions of Ubuntu displayes warnings if Caps Lock or Num Lock buttons are activated. 12.04, at the present stage, displayes warning only when Caps Lock is enabled but a similar warning is not displayed for Num Lock.
