This is an How-To guide on getting a Touch Screen Film working in Linux. The Touch screen I use here was. It is a 7″ USB based touch film layered on a glass screen. This can be used along with a.In this case, I have set it up with a Raspberry-Pi system + 7″ Lilliput monitor + raspbian OS (Debian derivative Linux). In another post. This guide focuses on getting touch screen worked. This one is coming from D-WAV Scientific Co.

It comes with USB interface.7-inch USB Touch Screen FilmHere is how to identify the device I mentioned here.$ lsusb.Bus 006 Device 002: ID 0eef:0001 D-WAV Scientific Co., Ltd eGalax TouchScreenThe Linux kernel version is 3.2.27-cutdown+ from raspbian.UPDATE: The first step in getting this done is to compile the raspbian kernel with necessary kernel module. Before compiling, in menuconfig we include usbtouchscreen module, which supports this touch screen film. Here is where do we need to find this module.Device Drivers - Input device support - Generic input layer (needed for keyboard, mouse, ) - Touchscreens (INPUTTOUCHSCREEN =y) - TOUCHSCREENUSBEGALAX =yOnce kernel compiled and rebooted with new kernel, it should be detected as USB Touch Screen of Serial Input device as observed below.

The usbtouchscreen module loaded automatically.$ demsg.usb 1-1.3.3.2: new low-speed USB device number 9 using dwcotgusb 1-1.3.3.2: New USB device found, idVendor=0eef, idProduct=0001usb 1-1.3.3.2: New USB device strings: Mfr=1, Product=2, SerialNumber=0usb 1-1.3.3.2: Product: USB TouchControllerusb 1-1.3.3.2: Manufacturer: eGalax Inc.input: eGalax Inc.

For me the xserver-xorg-input-evtouch package in repository failed to function. So I downloaded the source tar file and patch from.Apply the patch and build the source to get evtouchdrv.so. Once installed you should have it in /usr/local/lib/xorg/modules/input/.Now it is time to edit xorg.conf file.
