Lock Keyboardon screen?

[pixelated]

For some reason i cant type more than 20-30 characters into a term emulator in libertine cont, before the keyboard vanishes and refuses to reappear, until i goto a UT app, but it refuses to stay on screen when going back to terminal

Is there some way to lock it in place? cant see an obvious option.

(Onboard worked for a whilw, but doesnt seem to with any terminal emulator).
