Hmm. That's a big disappointment.

I've been using "ts_calibrate" in the past, and that worked just fine on this 
board.

Sato uses an X application for this, and it's apparently borked or so.

It does not run at startup, as I'd expect it to do (though it seems to be 
setup for that).

running "DISPLAY=0:0 xinput_calibrator_once.sh" displays it, but it doesn't 
really work. I can only "touch" the crosses in the upper left and right 
corner, but it does not accept the lower right one.

I ran it with the "-v" option to get some more info, and this is what it 
displays when I click the crosses. The lower left one causes the "Not 
adding..." output.
