Comment on LG L1730SF touch screen display in Ubuntu Linux 8.04 Hardy Heron, part 3 by Mårten

I am using an LG1510SF monitor which is quite similar to the 1730.

I am setting it up on a thin client which means that I need a light weight OS. For that I have choosen puppy linux (5.0.1 LuPu based on Lucid Lynx).

The problem I get is that xorg.o.log tells me:
evtouch.c: undefined symbol xf86getmotionevents
and thus fails to load the driver. This leaves me with only the imt driver which, as you know, mirrors the x axis after an xy swap.

Do you have any suggestions on what I might do about this?

The easy way to get the touchscreen to work in Ubuntu 10.04 Lucid Lynx is to install evtouch and just fix the broken evtouch xorg.conf.d snippet. No HAL or udev methods required (and they wont work anyway).

Wrote more about this in my blog here http://www.viitalat.net/index.php/htpc/2010/07/16/lg-1730sf-on-ubuntu-10-04

those values indicated above are the ones that should be used for xorg.conf file,,am having problems including the xml lines for the corresponding fdi file. Those values should apply as follows on the xorg.conf file.

Section “InputDevice”
Identifier “touchscreen”
Driver “evtouch”
Option “reportingmode” “raw”
Option “Emulate3Buttons” “true”
Option “Emulate3Timeout” “50″
Option “sendcoreevents” “On”
Option “maxx” “3815″
Option “maxy” “3948″
Option “minx” “295″

I found something on this from our wiki which was probably long published and thought it might help some of you guys…I tried it on ubuntu 9.10(karmic koala) with my touch screen being LG FLATRON L1730SF and it worked perfectly without doing any extra calibration or having to deal with jumpiness. I did it on a fresh install.

just follow the steps:

install evtouch

sudo apt-get install xserver-xorg-input-evtouch

see if the device is loaded

cat /proc/bus/input/devices

should see something like this

I: Bus=0003 Vendor=0403 Product=f9e9 Version=0100
N: Name=”ITM Inc USB Touch Panel”
P: Phys=usb-0000:00:1d.2-1/input0
S: Sysfs=/devices/pci0000:00/0000:00:1d.2/usb4/4-1/4-1:1.0/input/input5
U: Uniq=
H: Handlers=mouse2 event5
B: EV=b
B: KEY=400 0 0 0 0 0 0 0 0 0 0
B: ABS=1000003
. . .

create fdi policy file

This fdi file work ok for my LG L1730SF touch screen. I saved it as: /etc/hal/fdi/policy/lgtouch.fdi. Copy and paste the lines below in your file

evtouch
raw
true
50
on
3815
3948
295
200
CCW
true
false

Ubuntu 8.04.4 ( probably all 8.04 versions)

I have correctly set up udev.rules as described in the article.

At random boots the /dev/input/touch points at mouse1/2 instead of event5.

In that cases the touchscreen is not calibrated ( it works, probably with usbtouchscreen driver and not with evtouch )

I found that restarting udev ( /etc/init.d/udev restart ) fixes the /dev/input/touch to correct event.

After the event is correct, restarting X makes the calibration work.

An idea will be to execute “/etc/init.d/udev restart” before starting gdm .

Hope it will be useful for someone.

I kind of love the Asus Eee PC because it is very small and very light. I have an Acer Laptop and it is really a big burden on my small shoulders .
