I bought a 19" touchscreen without doing enough research on it. It works except the arrow will not track my stylus. when I drag the arrow moves in the opposite direction of my finger. Can this be fixed or did I waste $260? I did do the admin touchscreen calibration.

Which touchscreen did you get?
when you do a ADMIN TOUCHSCREEN does it identify yours correctly
I don't have one so mine shows this
ADMIN TOUCHSCREEN
list of xinput devices:
"pointer"       id=0    [XPointer]
"keyboard"      id=1    [XKeyboard]
resetting currently set calibration data in xinput
xinput set-int-prop "eGalax Inc. USB TouchController" "Evdev Axis Calibration" 32 0 2047 0 2047
unable to find device eGalax Inc. USB TouchController
xinput list-props "eGalax Inc. USB TouchController"
unable to find device eGalax Inc. USB TouchController
Error: No calibratable devices found.

you can check the ~/gcode/logfiles for both the
pathpilotlog.txt & xinput_calibrator.pointercal.log

if you can paste the realavant messages might be able to help

ultimately it will probably be running xinput to set it up corectly

Thank you for your reply. it seems to work fine except the the pointer moves in the opposite direction of the stylus. ie if I drag toward top right, it goes towards bottom left. it even acts like it calibrates correctly.
This is the one I bought www.ebay.com/itm/19-5-Wire-Touchscreen-L...d66:g:-t0AAOxycERRkj

I will check the log files. Thank You

If you are moving in the wrong direction, it is possible that the system thinks the monitor is oriented upside down.
Is there any options in your display setup to rotate the screen? Does that help?

Do you mean to flip the whole physical unit or flip it in the software? If I flip the physical unit wont the display be upside down? I know many may laugh at that question, but I am a newby, please be patient. I did not find an option to rotate the screen in the monitor menu. If there is one on the pathpilot controller I do not know how to find it.

I talked to tormach CS, they said they have seen this issue before and it was bad monitors. I am returning this one.
