You are so right about the trick to find what file needs to be edited.
Replied by tecno on topic Touch panel question
I have struggled with the same thing every time I've tried to install a touch screen. The trick is figuring out what configuration file needs to be edited to save the changes. It seems to be different for every Linux distribution version.

I would like to see the output of
Have you tried this yet:
linux-tips.com/t/usb-egalax-touchscreen-...em-with-debian-9/551
It mentions installing xserver-xorg-input-evdev package, which is available for stretch, with a conf stanza
sudo lsub -v -d 0eef:0001

hmmmm usbtouchscreen should be load
if you run lsmod can you see usbtouchscreen loaded ?
Can you post the output of
cat /proc/bus/input/device
The bit that has me worried is Vendor Specific Class, one would expect to see mention of HID.

Will do that shortly, have to go shopping food ![;) ;)](/media/kunena/emoticons/wink.png)
I suspect that I have made a bobo as regards how I installed the touch. Find no markings on what is up and front.
Looking at the drawing the 4 wires goes out on right side, but what is front and what is back?
On the milling machine the touch is mounted in reverse to drawing = 4 wires go out left and here only clue what is back/front is the adhesive to set it on the monitor.
So this could very well explain why pointing left cursor goes right.
On the lathe 4 wires goes out right but here there was no adhesive so it might be flipped as here touching low cursor goes high.
Obviously there is no way to set the calibration parameters that stick in the conf file.
So I will try to shift Y min max wires on the lathe to see if that solves the problem. and X on milling machine.

Progress but not OK. Touch and cursor are in the same place more or less but I can not reach edges.
Shifted Y axis wires on the lathe and now we are close. Now it is time to get calibration values to stick but the one-million$ question is what file and where
