calibrating Elo touchscreen - ubuntu 9.10 or 10.4

[ahoros]

I am having tough time connecting my external Elotouch intelitouch monitor to Dell latitude D420 laptop.
(via USB)

That is kernel is properly detecting the device - however the coordinates are reversed.
e.g. up is down and right is left

I have found examples how to configure it via xorg.conf -- however I belive that under recent version of x.org that file is not used anymore.

Moreover the utility for calibration does not work:
root@wali:/etc/X11# ts_calibrate
ts_open: No such file or directory


I tried both 9.10 and now I am struggling with 10.4 --- with no success.

I would appreciate any pointers - anything that I was able to google on the web seems to be outdated.

Thanks

[ahoros]

I guess the question is should I try to install additional drivers for xorg
and try to configure it via xconf.org -- as most sites suggest (albeit for older version of kernel / xorg)

or is there any way to pass arguments to kernel
since it seems to be doing OK job of detecting the elo touch screen:

some people suggested passing arguments to HAL (for instance: "wacom.fdi" in /etc/hal/fdi/policy) --- but no HAL anymore in 10.04 ...... and anyway I have Elo.

Could not initialise connection to hald.
Normally this means the HAL daemon (hald) is not running or not ready.

Hurray!

I found a solution in the following thread:

And here is the summary of what has worked for me - re: the ELO touchscreen is reversed/backwards problem:

Still need help! --> how to calibrate touchscreen

direction reversal problem is solved - but the screen still needs calibration - on the right hand side of the screen the mouse movement to actual touch area is off by about 1 centimeter!

The tslib calibration library seems to be still broken despite 10.4 final status )-:

[Interruptor]

I've made this [quick and ugly] script to calibrate "Elo TouchSystems Inc. Elo TouchSystems IntelliTouch 2500U"

device_id=$(zenity --entry --text="`xinput list`\n_________\n\ndevice id:")
minx=1000
maxx=3655
miny=960
maxy=3314
errors_status=""
while `zenity --question --text="$errors_status\n___\n\n$minx,$maxx,$miny,$maxy\nAgain?"`; do 
	minx=`zenity --scale --text="min-x" --value=$minx --min-value=500 --max-value=1100 --step=5`
	maxx=`zenity --scale --text="max-x" --value=$maxx --min-value=3200 --max-value=4000 --step=5`
	miny=`zenity --scale --text="min-y" --value=$miny --min-value=800 --max-value=1100 --step=5`
	maxy=`zenity --scale --text="max-y" --value=$maxy --min-value=3000 --max-value=3600 --step=5`
	errors_status="`xinput --set-prop "$device_id" "Evdev Axis Calibration" $minx, $maxx, $miny, $maxy 2>&1`"
done

For standing: 1000,3655,960,3314

[Noob Programmer]

Thanks so much for that calibration script. I had to change the min and max values past what you were allowing.
min-x 50
max-x 3990
min-y 50
max-y 4080

[Interruptor]

Detection of device id:

device_id=`xinput list | grep Touch | grep -o "id=[0-9]*" | sed 's/id=//'`

[Interruptor]

Just found http://sourceforge.net/projects/evcalibrate/
Can someone test it and post returned values here?
Because I will be able to test it myself only in 2+ days.

If it's working, then we can mark thread as solved.

Hi,

On this elo thread dglnz used touchcal to calibrate.

[Interruptor]

Yeap, evcalibrate working perfectly.

$ sudo ./evcalibrate /dev/input/by-id/usb-Elo_TouchSystems_Inc._Elo_TouchSystems_IntelliTouch_2500U_07U01964-event-mouse
xinput set-int-prop "Elo TouchSystems Inc. Elo TouchSystems IntelliTouch 2500U" "Evdev Axis Calibration" 32 990 3686 936 3341
xinput set-int-prop "Elo TouchSystems Inc. Elo TouchSystems IntelliTouch 2500U" "Evdev Axis Inversion" 8 0 1
xinput set-int-prop "Elo TouchSystems Inc. Elo TouchSystems IntelliTouch 2500U" "Evdev Axes Swap" 8 0

So, 990 3686 936 3341 for 17" IntelliTouch 2500U

Just had to make and run it under root and installed next packages before compiling:

libqt4-opengl-dev
qt4-qmake

I think this should be added to first post and thread marked as solved.

Favux, thanks, but touchcal is not my case:

Supported Hardware
------------------
- EloGraphics(R) IntelliTouch E281-2310 (serial)
- MicroTouch(R) SMT3 (serial)

No USB touchscreens are supported at this time, but patches to support
different configurations and new hardware are very welcome.
