I have now 3 IIyama touchscreens with eGalax touchpanels the:
2x IIyama T1931-SR-b (5 wire resistive)
IIyama T1931-SAW-b (Acousic Wave)

The 1st screen (SR) worked out of the box and retained it's calibration but needed a startup script and udev rule

# xinput list # to find the map-to-output value
# xrandr # to find the output plug name
xinput map-to-output 9 DVI-I-1

The 2nd screen (SR) worked orignally out of the box and after a week it lost it's calibration and was impossible to get calibrated again. As you touch closer to the top right corner the mouse moves more to the left of your finger)

The 3rd screen (SAW) doesn't react to touch at all and I'm still fighting with it to get it to work.

There needs to be a better way for evdev to save and store the configuration for touchscreens. Especially for screens so well documented like the eGalax touchscreens.
