How to configure a Siemens basic touch display

Written by Florian Astenwald , IGEL COMMUNITY Member


I had a problem with Siemens Touch Basic Displays and wanted to share the solution how we solved the issue.


As touch driver I used eGalax. With this driver the device can be operated via touch, but unfortunately some functions were missing.

  • Scrolling does not work

  • Pinch to Zoom does not work

  • On-screen keyboard opens at the first try only the 2nd time, if you press the corresponding button.

  • On-screen keyboard does not open when typing in an input field of Chromium.

We used Chromium as our main application and I tried some Chromium parameters unfortunately without success.


We created a custom application and run a script that looks for the Touchscreen ID and uses that ID to launch the chromium-browser:


This is the script we are using:

First you have to know witch touch driver you are using, in our case eGalaxTouch


With this solution you can scroll, but pinch to zoom is not possible.


#!/bin/bash

SCREEN=`xinput list | awk '/eGalaxTouch/ { gsub(".*id=",""); print $1 }'`

exec chromium-browser --touch-devices=$SCREEN


For the onscreen keyboard we installed a chromium extension.


I hope this is helping others, that faced the same problem.
