Touch Screen Calibration - Transformation matrix & Overscan
0
So - I have a machine running a 7" touchscreen and the touch screen is placed behind a smaller 6" opening, I have used overscan to make the screen align with the opening which worked well. But now my problem is trying to calibrate it with the new size! I have used xinput calibrator - changes nothing. I then realized that I needed to use a transformation matrix for this - so I followed a wiki article on Arch linux - this changed something but not in the right way! The screen resolution is 1024 x 600 Overscan: Left: 60 Right: 60 Top: 60 Bottom: 5 c0 = touch_area_width / total_width c0 = 904 / 1024 c2 = touch_area_height / total_height c2 = 535 / 600 c1 = touch_area_x_offset / total_width c1 = 60 / 1024 c3 = touch_area_y_offset / total_height c3 = 60 / 600 Can you see anything wrong?
