How to get Gvision L15AX-JA touch screen working


I have a Gvision L15Ax-JA ( a serial touchscreen device) that I have tried to get working with Ubuntu 8.04, Ubuntu 8.10, Debian Etch and Debian Testing. Most helpful so far has been this article:
http://sudan.ubuntuforums.com/showth...=975395&page=3

Basically I have:
Code:
apt-get install build-essential xserver-xorg-dev
to get the needed files for compiling the drivers. Sometimes I need libx11-dev.

I then get the source for the drivers and the programs for the Gvision touch screen:
Code:
wget http://www.higgstec.com/download/COM/TS-COM-Linux.rar

unrar TS-COM-Linux.rar

cd ./TS-COM-Linux/TS_COM_Linux_V202

tar -xvf tscom-source-2.0.2.tar.gz
Then I go into:
Code:
cd tscom-2.0.2/drivers/xorg-7.3
./configure --prefix=/usr
make clean
make
sudo make install
And I do the same for tscomxp and the calibrate and rightclick programs.

Sometimes I need to check the X version and version of glibc.
Code:
X -version

/lib/libc.so.6
because sometimes when building I get an error message:
Code:
********* CHECKOUT THE GLIBC VERSION! MUST BELOW 2.3
GLIBC_2.4
GLIBC_2.1
GLIBC_2.0
*********
but I don't know what to make of this or if I need to change it.

Things seem fine, I get data when I
Code:
cat /dev/ttys1
but when I run the calibrate program nothing happens.
I see the drivers are there:
Code:
$ ls /usr/lib/xorg/modules/input
evdev_drv.so  mouse_drv.so      tscom_drv.la  tscomxp_drv.la  vmmouse_drv.so
kbd_drv.so    synaptics_drv.so  tscom_drv.so  tscomxp_drv.so  wacom_drv.so
So far it seems that it might be a problem with the xorg.conf
Code:
Section "Device"
	Identifier	"Configured Video Device"
EndSection

Section "Monitor"
	Identifier	"Configured Monitor"
EndSection

Section "Screen"
	Identifier	"Default Screen"
	Monitor		"Configured Monitor"
	Device		"Configured Video Device"
EndSection

Section "InputDevice"
         Identifier "TSCOM_Touchscreen"
         Driver     "tscom"
         Option     "Device"           "/dev/ttyS1"
         Option     "DeviceModel"      "TS"
         Option     "ScreenNo"         "0"
         Option     "SendCoreEvents"   "yes"
EndSection
Section  "InputDevice"
         Identifier "TSCOM_Calibration"
         Driver     "tscomxp"
EndSection

Section "ServerLayout"
	Identifier    "Default Layout"
	Screen        "Default Screen"
	InputDevice "TSCOM_Touchscreen" "SendCoreEvents"
	InputDevice "TSCOM_Calibration"
EndSection
I've tried adding "CorePointer" instead of "SendCoreEvents" but that didn't seem to make much of a difference.

What should / shouldn't be showing up in /proc/modules ?

Any other ideas for the xorg.conf?

trouble shooting?

loading / unloading modules?

same problem

hi donnied,

I have been struggling with the same problem as yours, but only tried Ubuntu 8.10
where TSCOM drivers and programs compiled smoothly (thanks to your post).

But I can't get anything from any of the /dev/ttyS* (0 to 3) while touching the screen.

I see you haven't received any response... have you managed to get it working eventually ?

In advance, many-many thanks,

The tscom drivers were the wrong drivers for the monitor. I did a fresh install with no faulty tscom driver installs and installed
Code:
xserver-xorg-input-elographics
and I was good to go. I just had to calibrate. I posted my xorg.conf here:
