Get Touchscreen eGalaxy Touch working

Product support
38

Let’s summarize:

  1. Remove the ft5406 overlay as the device is supported by default.
  2. You need an X driver which connects the input devices to the X server - the opensource one works just fine for your device (xserver-xorg-input-evdev). You can use xinput (you can install it as well) to see if X can detect your input device. As soon as the X driver was install (and after X restart) you can see that X can detect the input device:
root@raspberry-pi2-cfcd83d:/# DISPLAY=:0 xinput
⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
⎜   ↳ eGalax Inc. Touch                       	id=6	[slave  pointer  (2)]
⎜   ↳ eGalax Inc. Touch                       	id=7	[slave  pointer  (2)]
⎣ Virtual core keyboard                   	id=3	[master keyboard (2)]
↳ Virtual core XTEST keyboard             	id=5	[slave  keyboard (3)]
  1. Using the calibration tool (xinput_calibrator) we generated the correct parameters for the device and used it statically in the app to be persistent for the fleet.

Hope this clarifies.
