I own a notebook with separate number pad on the keyboard and running 16.04.
On the login screen/lock screen, I see a grey warning triangle in the password input field telling me that NUM-Lock is on.
However, as this keyboard has a separate number pad which is not integrated into the letter keys, I don't need this warning. If I remember correctly, the warning is not existing on desktop installations at all anyway.
How can I disable this warning? I want the CAPS-Lock warning to remain enabled though.
