OK...I gout rid of that from xorg,conf:

After this, still issue with cursor not tracking where clicks occur on
touch screen.
Try starting without any calibration set, or set it to smth safe like
xinput set-int-prop "Touchscreen" "Evdev Axis Calibration" 32 0 1000 0 1000
With values above, then calibration:
xinput list-props Touchscreen Device
'Touchscreen':
Device Enabled (136): 1
Device Accel Profile (244): 0
Device Accel Constant Deceleration (245): 1.000000

(250), "Button Unknown" (250), "Button Wheel Up" (140), "Button Wheel

Evdev Wheel Emulation Inertia (263): 10
Evdev Wheel Emulation Timeout (264): 200
Evdev Wheel Emulation Button (265): 4
Evdev Drag Lock Buttons (266): 0
If I run calibration again (output of calibration is different):
xinput list-props Touchscreen
Device 'Touchscreen':
Device Enabled (136): 1
Device Accel Profile (244): 0
Device Accel Constant Deceleration (245): 1.000000

If that does not help, then we should figure out why you get different
calibration results with different runs.
Try running running the calibrator a few times starting with the same
base calibration values (eg 0 1000 0 1000) and check by adding the -v
flag what clicks are registered and what calibraton is calculated.
Running calibration again starting with same base valies with -v:
./xinput_calibrator_x11 -v

== Making the calibration permanent ==
If you have the 'xinput' tool installed, a simple way is to create a
script that starts with your X session, containing the following command(s):
xinput set-int-prop "Touchscreen" "Evdev Axis Calibration" 32 -90
761 -106 744
If you have evdev version 2.3.0 or higher, there are 2 more ways: the
tranditional way (xorg.conf) and the new way (udev rule):
xorg.conf: edit /etc/X11/xorg.conf and add in the 'Section
"InputDevice"' of your device:
Option "Calibration" "-90 761 -106 744"
udev rule: create the file '/etc/udev/rules.d/99_touchscreen.rules' with:
ACTION!="add|change", GOTO="xorg_touchscreen_end"
KERNEL!="event*", GOTO="xorg_touchscreen_end"
ATTRS{product}!="Touchscreen", GOTO="xorg_touchscreen_end"
ENV{x11_options.calibration}="-90 761 -106 744"
LABEL="xorg_touchscreen_end"
Again:
Skipping to relevant parts:

DEBUG: Adding click 2 (X=2, Y=499)
DEBUG: Adding click 3 (X=652, Y=502)
This shows that although the calibration values differ in different
runs, the clicks received by the calibrator are always at just about
the same coordinates.
This means that the calibration values are ignored.
Not sure what goes wrong...
Peter, do you have an idea ?
Kind regards,
Tias
