Never saw what onboard? Onboard is the on display keyboard most Linux distros have like how windows 98, xp vista & 7 have in their accessibility a on screen keyboard. The picture of the windows 10 touchscreen keyboard is the default built keyboard in windows 10. It's on by default in every 2 in 1 laptop with touchscreen & tablet as I said this is in my previous posts if you were reading. I'm sure on desktops you can turn on the touch screen keyboard if you decided to replace your monitor with a touchscreen one.
