Set the gnome onscreen keyboard

Zorin 17.2 Pro
Lenovo Yoga 380

At basic install there is an isane large ugly keyboard half the size of HD screen. So we can install cellwriter what is keyboard and stylus input or improved gnome keyboard.
The question is, how to set which if these installed keyboard is to be used?

Hanselinux

are you on gnome or xfce?
Zorin Pro or Zorin Pro Lite?

I'm on Zorin-Pro 17.2

Have installed the cellwriter onscreen keyboard.

ii cellwriter 1.3.6-3build1 amd64

The only keyboard that popup on the HD screen is a half HD screen size from gnome. Somewhere in the gconf should be the secret. But don't have a clue where.

Found this, it's a bit nicer and can be installed. Cellwriter would be nicer
