On and off, for the past few days, I unsuccessfully try to get the 3.5 LCD display working on my pi3 with the latest stretch. The LCD is this:
Keyestudio TFT LCD Display 3.5 Inch 480x320 16-bit TFT Touch Screen LCD Shield for Raspberry Pi Model B B+ A+ A Module
a wareshare35a lcd
I followed this instruction to install the driver:

After reboot, the LCD works. But the touches are all off, when I use the mouse to click on an icon, the correct icon opens the correct app, no a problem. However, this doesn't hold true for finger tap nor for stylus. when I tap on an icon with my finger or use the stylus. the mouse curser does not response to the right location on the LCD, for example, when I click on and icon on the lower left side of the LCD, the mouse curser stay on the upper right side time pi icon. It opens a calendar instead. I tried to calibrate it with the xinput-calibrator, pasted the data to the /etc/X11/xorg.conf.d/99-calibration.conf, reboot. Nothing changes. Have I missed some steps? Thanks.
