Regarding How to disable on screen keyboard on ubuntu 18.04 LTS

[Koutilya Gurjikindi]

Dear Ubuntu Quality Team,

I am writing to you today to report a bug in the Ubuntu 18.04 keyboard
disabling feature. I have tried to disable the keyboard using the gnome
commands, but the keyboard automatically re-enables when I enter a text
input field. I have also tried using Block caribou and onboard, but these
tools did not work either.

I have attached the output of the gnome commands that I used to disable the
keyboard. I have also attached the output of the error messages that I
received when I tried to use Block caribou and onboard.

I would appreciate it if you could look into this bug and let me know if
there is a way to permanently disable the keyboard in Ubuntu 18.04.

Thank you for your time and consideration.
