Re: uts(4) touchscreen calibration

Hi

I was able to calibrate all of the touch screens on laptops I've had reporting 
as absoule coordinate wsmouse(4) devices.

I had written a small program which I was able to use to find the bounds of the 
screen.  It will print all wsmouse packets, run the program | tee file then use 
grep and sort for the particluar axis.

Then once you've found the coordinates of the touch screen apply the settings 
to your xorg.conf for the ws(4) driver eg:

Section "InputDevice"
        Identifier  "Touchscreen"
        Driver      "ws"
        Option      "Device" "/dev/wsmouse1"
        Option      "ButtonMapping" "1 2 3"
        Option      "Buttons" "3"
#       Option      "DebugLevel" "5"
        Option      "MinX" "1225"
        Option      "MaxX" "15600"
        Option      "MinY" "760"
        Option      "MaxY" "14270"
EndSection

Best regards,
