Hi Everyone,
Using a combination of various google’d posts from other sites, I’ve been able to cobble together something that kinda works, except that the mouse cursor fails to move/respond when the screen is touched.
My relevant configuration entries for the /etc/X11/xorg.conf file as as follows:
Section “ServerLayout”
Identifier “X.org Configured”
Screen 0 “Screen0” 0 0
InputDevice “Mouse0” “CorePointer”
InputDevice “Keyboard0” “CoreKeyboard”
InputDevice “TouchScreen” “SendCoreEvents”
EndSection
Section “Module”
Load “dri2”
Load “glx”
Load “extmod”
Load “vnc” # TODO: Commented out, as Xvnc fails to work.
Load "dbe"
Load "dri"
Load "elographics"
EndSection
Section “InputDevice”
Identifier “TouchScreen”
Driver “elographics”
Option “DeviceName” “Elo”
Option “Device” “/dev/ttyS0”
Option “Port” “/dev/ttyS0”
Option “AlwaysCore”
Option “CorePointer” “true”
Option “screenno” “0”
Option “MinX” “0”
Option “MaxX” “4000”
Option “MinY” “0”
Option “MaxY” “4000”
Option “UntouchDelay” “3”
Option “ReportDelay” “1”
Option “debuglevel” “5”
EndSection
The Log file outputs:

Again, I’ve trimmed out all the non-elo related cruft to try to keep this post small, if more of the log file is required I can post those specific sections.
Because I have the debug level set, when I run my finger across the screen I see the following output in the /var/log/Xorg.0.log file:

This tells me the driver is loaded, but somewhere there is a disconnect and the events are not being transmitted to the Core Pointer facility. I suspect that the following error in the log file (during hardware initializations in X) may be the root of my problem:

Any ideas/help would be much appreciated, thank you.
