Hardy / touchscreen calibration doesn't work on panasonic t2 (driver evtouch)

[tymeo]

Binary package hint: xserver-xorg-input-evtouch

laptop: toughbook t2 with touchscreen , Hardy.
I managed to get the touchscreen working on Gutsy with this examples:

http://ubuntuforums.org/showthread.php?t=419235 (in english)
http://www.nextabyte.com/support/touchscreen/ (in english).
Both driver and calibration tool worked well, but when i tried Hardy, the touchscreen worked out of the box, but i didn't find how to calibrate it.
I didn't have to install the evtouch driver to get the touchscreen working so i don't know if it is a real bug of this package.

I tried to copy my gutsy's xorg.conf in Hardy, but it seems that xorg 7.3 doesn't use this file anymore.
here is the specifications on the touchscreen:

What's built-in for touchscreens with 2.6.24?
I'm working with SLAX 6, which is based on the very latest (7.3) xorg and uses a 2.6.24 kernel (derived from Slackware 12.1). I'm trying to get a touch screen working. The vendor provides closed-source drivers, which need to be recompiled to work with the latest xorg (which he's promised to do for me, but I have no idea how long that will take). I had other problems getting the venerable evtouch_drv driver working.

The rub is that my touch screen actually almost works already! It seems that the usbtouchscreen driver in linux and the built-in mouse drivers in X pretty much know what to do. The only problem is that I don't know how to calibrate things. So my mouse cursor doesn't quite reach the left and right edges of the screen, and it goes a a little beyond the top and bottom.

It seems odd to me that Linux/Xorg would go this far providing touch screen support, but not take the extra step of giving me some way to calibrate.

I'm guessing that instead of using /dev/input/mice, I'd set up separate InputDevice sections in my xorg.conf for the real mouse, and for the touchscreen "mouse", and then I'd give the touchscreen "mouse" some extra options for calibration. But I can't find any documentation on what those options might be.

Or perhaps there is some way to push parameters down into the usbtouchscreen driver?

Any ideas?

I have the same bug on my Fujitsu Siemens P1620 w/ Hardy Heron RC.

For short,
I am having same question

I have a Toughbook T2 and Ubuntu Hardy. Touchscreen works but needs to be calibrated.

Hi tymeorama,

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with the latest development release of Ubuntu? (ISOs are available from cdimage.ubuntu.com)

If it remains an issue, could you also attach a new /var/log/Xorg.0.log?
Thanks in advance.

The output of lspci -vvnn would also be worth having.

Hi,
I finally get my touchscreen to work with this how-to found on the french
ubuntu website.
http://doc.ubuntu-fr.org/evtouch?s[]=evtouch

Sorry, but i have not translated it in english, but i think that you may
find the informations you need.

I have not tested this how to with Ibex, only with Hardy.

Best regards

 Introduction

Cette aide permet d'installer et de configurer un écran tactile type egalax
USB présent sur certains moniteurs et sur les UMPC ou tablettes Internet. Je
ne garantis pas que cette aide fonctionne pour toutes les configurations.

afin de vérifier le modèle de dalle tactile tapez dans un terminal :

Can't we have an evtouch 0.8.8 backport to Intrepid? It would cure so many bugs about touchscreen.

Thanks for packaging for Jaunty, in the first place ;)
