On Screen Keyboard in Mint 17

[Billaboard]

I'm trying to get an X60 tablet working sensibly in tablet mode with Linux Mint 17 Cinnamon. I am an eternal beginner with Linux.

I activated the built in on-screen keyboard, but it doesn't seem very user friendly. Examples include: If I hit the menu button, I get the programs menu, but with the keyboard on top. When I cancel the keyboard, the menu goes too. It also doesn't ever seem to appear for, and link to, LibreOffice.

I installed "Onboard", which also seems impossible to set to any sort of auto-appear mode and also doesn't seem to link to Office, although I did seem to get this going briefly.

Any pointers to simple instructions to get this working, or confirmation that it can work, gratefully received.

Thanks
