How do I turn off the onscreen keyboard on the lock screen?

Question

The lock screen has an on screen keyboard that I am unable to disable. I don't remember exactly but I believe I turned it on using the "Screen Keyboard" setting in the Universal Access settings. I've tried a number of things all with no effect:

• Toggling "Screen Keyboard" in Universal Access
• Toggling "Onscreen keyboard" in the login screen (LightDM)
• Clicking on the "x" in the upper right corner of the keyboard

Answer 1

In the Dash, open Onboard Settings.

Unmark Show Onboard when unlocking the screen.

Done.
