Imported via HTML fallback (before-primary)

New page

Using serial connection only:
NOTE: If the monitor is USB/serial and an active USB cable is plugged in the serial port is disabled!

== Connecting the touchscreen with EVDEV and inputattach ==

These seems to be a more elegant way to use the touchscreen today:

modprobe elo

inputattach -elo /dev/ttyS0 --daemon

You can create a udev-rules, to load inputattach automatically

== Using the X11-elographics driver ==

MaxX, MinX, MaxY & MinY option settings are pretty close but proper calibration is best.

Installed debian driver package for elo serial touchscreen (not for USB)

aptitude install xserver-xorg-input-elographics

Create Input Device entry in /etc/X11/xorg.conf

Section "InputDevice"
Identifier "Touchscreen"
Driver "elographics"
Option "screenno" "0"
Option "ButtonNumber" "1"
Option "ButtonThreshold" "17"
Option "Device" "/dev/ttyS1"
Option "InputFashion" "Touchpanel"
Option "MaxX" "4025"
Option "MinX" "22"
Option "MaxY" "3967"
Option "MinY" "75"
Option "Name" "ELO Touchscreen"
Option "ReportingMode" "Scaled"
Option "SendCoreEvents" "on"
EndSection

Add Input Device to "ServerLayout" section

InputDevice "Touchscreen" "SendCoreEvents"

reboot or restart xserver

== Calibration ==

Download [http://touchcal.sourceforge.net Touchcal]. You need to install libncrses5-dev to compile the package so:

apt-get install libncurses5-dev

Then extract Touchcal and compile

./configure
make

Stop x11 server:

/etc/init.d/kdm stop

Run calibration:

./touchcal --elographics /dev/ttyS1

Follow the onscreen prompts and then add the coordinates in /etc/X11/xorg.conf as mentioned above
