I'm trying a Egalax touchscreen to work for a TPV on Ubuntu 18.04, but everything I tried didnt work at all. I tried to make it work with "calibrate touchscreen" as Ubuntu seems to detect the screen correctly, but no input at all from calibration. I tried with the Egalax driver as this tutorial: https://wiki.ubuntu.com/Touchscreen

And This other: eGalax Touchscreen Configuration Ubuntu 14.04LTS

But no luck. Nothing happens when I touch the screen. Here is my lsusb:

This is working on 5 of my machines and has the advantage that you can stop and start the touchscreen with systemD (systemctl status eGTouch.service)

Download the latest touchscreen driver from eGalax Untar the files

tar xvzf eGTouch_v2.5.5814.L-x

Run setup

sudo ./setup.sh

Create the SystemD .service file.

sudo systemctl edit --force --full eGTouch.service

Paste the following unit file modification

#######################################################
#### eGalax Touch Unit File for auto start on boot ####
#######################################################
[Unit]
Documentation=man:systemd-sysv-generator(8)

Then enable it

sudo systemctl enable eGTouch.service

Then restart it

sudo systemctl restart eGTouch.service

Then reboot

sudo reboot

  • Please note that the eGTouch_v2.5.6722.L-x.tar.gz driver is Broken! It throws the following error on a fresh install of Ubuntu 18.04LTS. (EE) event14 - eGalaxTouch Virtual Device for Single: kernel bug: device has min == max on ABS_TILT_X I've reported this to the vendor. Hopefully they will come up with an updated driver soon.

    've located the problem it's is in the the eGTouchD binary file. I installed the 2.5.6722.L-x driver before rebooting I replaced the eGTouchD binary with the v2.5.5814 version of eGTouchD binary in /usr/local/eGTouch64withX/eGTouchD rebooted. Now the touchscreen works properly.

    It looks to me like setup.sh already creates the systemd service. It creates a service called "eGTouchD.service". Using your instructions makes it so there are two services. Is this the intended result? Also, these instructions are the same as listed here: docs.google.com/document/d/…

  • @EvandelaCruz the default installed service fails to work on my Ubuntu, which is why I just run the script as root

I got it working for me. (USB connection, Ubuntu 18.04 64-bit)

  1. Download and install the eGTouch driver. Unpack the .tar.gz and run setup.sh as root. Answer the prompts according to your needs.
  2. Run this as root: crontab -e
  3. Add this line: @reboot /etc/init.d/eGTouch.sh
  • run this script at boot as root, will not work otherwise
  1. reboot

    Why start it by cron?

  • @Pilot6 it is the easiest way to run a script as root at time of bootup on Linux

    No, it is not nether the easiest, not the best way.

My solution was the following. (USB connection, Ubuntu 18.04, 64 bits)

What I did first was identify the driver:

xinput list

and then

  1. Download and install the eGTouch driver.

    wget https://www.eeti.com/touch_driver/Linux/20210716/eGTouch_v2.5.10206.L-x.tar.gz

  2. Extract the tarball

    tar zxvf eGTouch_v2.5.10206.L-x.tar.gz

  3. Run setup.sh as root.

    cd eGTouch_v2.5.10206.L-x
sudo ./setup.sh

  4. Next, cd to /usr/bin and run ./eGTouchU

    cd /usr/bin
sudo ./eGTouchU

  5. This command opens the eGTouch GUI.

  6. Go to the Tool tab.

  7. Click Clear Parameter and click the four points on the screen.

    Problem solved.

You can manually setup a mapping of the USB touch to X11:

  1. Use "xrandr" to identify the touchscreen crtc name, such as "DP-1"
  2. Use "xinput --list --name-only" to get USB touch name
  3. Use "xinput --map-to-output" to map the two.

My system is Ubuntu 16, Elo touchscreen as primary monitor.

$ xrandr
Screen 0: minimum 8 x 8, current 3840 x 1080, maximum 32767 x 32767
DP-0 disconnected (normal left inverted right x axis y axis)
DP-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 476mm x 268mm
   1920x1080     60.00*+
   1680x1050     59.95  
DP-2 disconnected (normal left inverted right x axis y axis)
DP-3 connected 1920x1080+1920+0 (normal left inverted right x axis y axis) 476mm x 267mm
   1920x1080     60.00*+  59.94    50.00  
   1600x900      60.00  
 

$ xinput --list --name-only
Virtual core pointer
Virtual core XTEST pointer
PixArt Dell MS116 USB Optical Mouse
HP USB Slim Keyboard
Elo multi-touch digitizer - 0 - 0eef:7200
Virtual core keyboard
Virtual core XTEST keyboard
Power Button

Final setup command. I placed it in "~/.xprofile".

xinput --map-to-output "Elo multi-touch digitizer - 0 - 0eef:7200" DP-1
