[yocto] Sato image touchscreen calibration is borked
On 11/13/2014 02:10 PM, Mike Looijmans wrote: Next challenge is to calibrate the touch screen... 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.

Not sure if this is a problem with the calibrator/xi not handling both axis being inverted, or something else is misbehaving. You're rapidly reaching the limits of my experience here - have you tried using the partial numbers that xinput-calibrator gave you for the broken touchscreen and extrapolating calibration setting to set manually?
