Re: Touch Screen Calibration Tool
@juan
you are awesome
heres what i did:
reinstalled the calibrate ts package in the repository
opened /usr/share/hal/fdi/policy/10osvendor/50-eGalax.fdi
changed the max/min value (this took the longest to realize somethimg
obvious)
after restarting X 50 billion times here is the final file for
/usr/share/hal/fdi/policy/10osvendor/50-eGalax.fdi
__code
evtouch
70
70
1900
1900
30
750
click
3
2
10
1
click
1
cw
false
false
/code
the rotate needed to be clockwise
and i didnt swap x or y
the MAX abslt edge is is 2000 the min edge is 0
then i bumbed it inside so to give me some room to touch it.
Thanks so much for helping! i had no idea about those fdi files
good luck juan

Actually, I think I got the same touchscreen a work in a project I'm
working on.
I have Ubuntu Mobile (customized) working on a VIA EPIA Mini-ITX with
the touchscreen you were talking about on the forum:
r...@rothera:~# lsusb
Bus 002 Device 002: ID 0eef:0001 D-WAV Scientific Co., Ltd eGalax TouchScreen
And is working. Actually was working from the begining, but the
calibrate was a mess. The cursor was doing weird things.
Now I almost have the perfect calibrate. I still testing options.
The driver I use is "evtouch" (xserver-xorg-input-evtouch) and I leave
hal to configure the Xorg. On Intrepid (at least) Hal gets the info of
the device from his database and the device itself and generate (on
the fly) the proper "virtual" xorg.conf.
Actually, the info for configuring the eGalax TouchScreen is stored
for this package on:
/usr/share/hal/fdi/policy/10osvendor/50-eGalax.fdi
But, at least for my screen, were wrong, so I had to changed them.
My first step was detect the max a min with the script the driver provide:
/usr/bin/calibrate_touchscreen
This script gave me the max (X/Y) and min (X/Y), and with those
details I could change the defaults values on the fdi file. The best
way to change that is to copy
/usr/share/hal/fdi/policy/10osvendor/50-eGalax.fdi into
/etc/hal/fdi/policy/ and then, change the values you need.
On that way, you don't mess with the original files (which will be, or
try to be, changed on any update of this package) but still will be
used. In fact, the files on /etc/hal/fdi/* will have more priority
than from /usr/share/hal/fdi/.
To see is the changes were made you need to restart hal:
$ /etc/init.d/hal restart
and then you can see the x11 options changed by doing:
$ UDI=$(hal-find-by-capability --capability input.mouse)
$ lshal -u $UDI
Those command gives you something like:
udi =
'/org/freedesktop/Hal/devices/usb_device_eef_1_noserial_if0_logicaldev_input'
info.capabilities = {'input', 'input.mouse'} (string list)
info.category = 'input' (string)
info.parent =
'/org/freedesktop/Hal/devices/usb_device_eef_1_noserial_if0' (string)
info.product = 'eGalax Inc. Touch' (string)
info.subsystem = 'input' (string)
info.udi =
'/org/freedesktop/Hal/devices/usb_device_eef_1_noserial_if0_logicaldev_input'
(string)
input.device = '/dev/input/event1' (string)
input.originating_device =
'/org/freedesktop/Hal/devices/usb_device_eef_1_noserial_if0' (string)
input.product = 'eGalax Inc. Touch' (string)
input.x11_driver = 'evtouch' (string)
input.x11_options.longtouched_action = 'click' (string)
input.x11_options.longtouched_button = '3' (string)
input.x11_options.longtouchtimer = '750' (string)
input.x11_options.maxx = '1912' (string)
input.x11_options.maxy = '1989' (string)
input.x11_options.maybetapped_action = 'click' (string)
input.x11_options.maybetapped_button = '1' (string)
input.x11_options.minx = '112' (string)
input.x11_options.miny = '76' (string)
input.x11_options.movelimit = '10' (string)
input.x11_options.oneandhalftap_button = '2' (string)
input.x11_options.rotate = 'ccw' (string)
input.x11_options.swapy = true (bool)
input.x11_options.taptimer = '30' (string)
input.x11_options.touched_drag = '1' (string)
linux.device_file = '/dev/input/event1' (string)
linux.hotplug_type = 2 (0x2) (int)
linux.subsystem = 'input' (string)
linux.sysfs_path = '/sys/class/input/input1/event1' (string)
So you can see the options hal has for the device. Now you need to be
sure there is not a any configurtion about the "Input Device" on the
xorg.conf file, to let hal configuring the X.
I paste you my fdi file for the eGalax TouchScreen, in case this help you:
evtouch
112
76
1912
1989
30
750
click
3
2
10
1
click
1
ccw
true
Now I playing with "input.x11_options.swapx" and
"input.x11_options.swapy", because I got a half mirror effect. The
limits are now fine, the horizont
