Umm.. first you need 'XServer' + 'XTerm' + 'Xecutah' all installed.
Then open 'Xecutah' and tap on 'Start XTerm'.
That should shortly bring up your keyboard and text window.. it might take a few seconds.
no, xecutah apparently does a check in 3 assistants. It checks if a pre/pixi, and sets the screen as small. It checks if touchpad or emulator, and sets "no gestures"... and if both fails, I suppose defaults to pre2/pre3
That means to a phone with a real kb.
The solution was to adjust all the tests, then as the initial new message xecutah offered, to install tweaks to finalize the thing.
The kb looks fix, and if the size is smaller a zone is left unused but that's all
