This bug was fixed in the package xf86-input-evtouch - 0.8.7-3ubuntu8

---------------
xf86-input-evtouch (0.8.7-3ubuntu8) intrepid; urgency=low

  * add 09_calibrate-script-halification.patch, adds hal functionallity to
    calibration tool, makes the script work under X and gives useful output
    through zenity dialogs
  * add 10_ev_calibrate_fixups.patch, fix ev_calibrate.c to use a useful font
    in calibration, make it write to /etc/evtouch/config in a format that can
    be parsed by the evtouch hal-set-property initscript
  * add calibrate.desktop and calibrate icon file (uuencoded), add sharutils
    to build-deps
  * make sure /etc/evtouch dir is created by the package so ev_calibrate can
    write its config there.
  * add hal to dependencies, zenity to suggests
  * add xserver-xorg-input-evtouch initscript to apply calibration data on
    system boot via hal-set-property
  * include .fdi files for ideaco and eGalax touchscreens (hopefully there
    will be more soon)
  * closes (LP: #261873)

The bug is not fixed for me as hal gives the error "Wrong UDI" :

libhal.c 2016 : invalid udi: --key doesn't startwith '/org/freedesktop/Hal/devices/'.
error: libhal_device_remove_property: (null): (null)

And it doesn't work (or, at least, I still don't understand how to make it works)

what kind of touchscreen is that ? it will only work with devices that have a valid .fdi file, i made several calls on mailing lists and via planet.ubuntu.com to send me lshal output for devices known to have worked before with evtouch. if you own such a touchscreen, please attach your lshal output to the bug ...

i will also add better error checking to teh UDI retrieving code, in case your device isnt known by hal it shouldnt attempt to calibrate it...

Sorry for being late but I have only access to this touchscreen since this week.

The touchscreen is a "Xernarc 7" 706 series."

In Hardy and in Intrepid, it's basically working well with evtouch except that it's very painful to calibrate and we still didn't succeed to have a good calibration. (The current one was done manually by trying/restarting X/modifying x.org)

I attach the lshal output. The touchscreen is on /dev/input/event2.

Also, as a side note : it seems from the documentation that we need to put the option Calibrate 1 in xorg.conf in order to make the calibration. Is it possible to add to the documentation an sample of a xorg.conf that is working with HAL,with the calibration line commented. It's indeed not really clear what should be in the xorg.conf and what will come from HAL. Do you want that I open a new bug for that ?

Thanks a lot for your work :-)

The Calibrate option is handled by hal on the fly now, with the last upload the evtouch calibration tool (which now has a menu entry in "System->Administration->Calibrate Touchscreen") will also notify users if their device isnt known by hal and instruct them how to generate useful lshal output and to send it to the ubuntu-mobile ML ... i will try to generate a .fdi file for your device during the day ... if it then works after calibration, can you please attach the /etc/evtouch/config file ? that way i can add a set of default values for it to the fdi as well so that it comes roughly preconfigured out of the box.

Just post a comment here once you uploaded the FDI. I will upgrade, calibrate and send you the config file. Thanks a lot :-)

I have a Panasonic "Let's Note" (Toughbook) T2. This FDI works for me. Great work with the new xinput integration guys, much better than the old "calibration by algebra" method I'd been using. I'm so excited I want to swear in text. No swearing on Launchpad right?

PS for those following along at home: I had to
  sudo /etc/init.d/hal restart
and restart X adding it to allow calibration.

I may have a better calibration after testing, but here's a first draft in case I drop the ball.

here is an excellent calibration for my Panasonic CF-T2.

lshal output in case the .fdi above needs to be made more selective. can this make it into intrepid?

  ....

  linux.sysfs_path = '/sys/devices/pci0000:00/0000:00:1d.2/usb3/3-1/3-1:1.0/input/input2/event2' (string)

most (all?) evtouch devices require a lower value for Option MoveLimit as in https://bugs.launchpad.net/ubuntu/+source/xf86-input-evtouch/+bug/204633

Can a value for this option be included in .FDI files? Not clear from linked issue whether one generic value works for all devices.

Setting movelimit to 2 in 10-Panasonic.fdi above makes drawing smooth in karbon14 etc. Should be the same for Fujitsu since they are really the same device. Can match contain an OR or regex in .FDI files? If so these could be merged (they just have a slightly different manufacturer string)

Here's a good .fdi file for my Lilliput 629GL. The CarPC people will be happy! This is an eGalax at heart, but actually has eGalax in the product, so the previous .fdi didn't work.

Wow I'm sorry, ignore the last post and use this file (I was using a few double-negatives in that configuration, really stupid). Again, this is for lilliput 629GL 7-inch eGalax touchscreen.

Also. here's the lshal for that lilliput 629GL in case it helps.

I have a Xenarc 700TSV. it responds to touch, however cannot be calibrated correctly.

This fdi file work ok for my LG L1730SF touch screen. I saved it as:
