Panasonic cf-28 how-to calibrate touchscreen in Ubuntu

Hi there,
i've got a Panasonic toughbook cf-28, running ubuntu 8.04 lts.
How can i calibrate the touch screen? I can't seem to find how to do that.
The problem with toughbook cf-28 is, that everything above ubuntu 9.04 the touch screen doesn't work without a special lib, or simply doesn't boot.

Also, for network administrating purposes, i like to run Back|track on the toughbook, so i can test my security. Do you know how or if the toughbook is supported by back|track? I mean, Does the touchscreen works "out of the box", or does back|track provides a specific lib or driver in their repositories....
Thanks in advance.

 

@aposteeltje,

NBR have a Panasonic Toughbook Forum, some of the guy's there know toughbooks & ubuntu "inside out" so it could be worth a visit.

o.g.

 

I moved this thread to the Panasonic forum (and added Ubuntu to the title) since it went a day without a reply in the Linux forum.

 

I haven't had any luck with my CF-28 and Lucy (10.04 Lucid Lync). The TS seems to be getting a touch input (the cursor moves), but it wont accept clicks. I dunno why. Eventually I gave up. Wasn't worth the hassle. The TS is recognized, so it shouldn't be hard to fix.

 

The touchscreen works perfectly using freedesktop.org - Software/xinput_calibrator you just install it then you add the resulting text in /etc/X11/xorg.conf.d/99-calibration.conf (I'm using archlinux + custom kernel).
All linux distributions are the "same" thing,only libraries version,package formats etc. may differ,so I think it should work on ubuntu,backtrack too.
Ubuntu 8.04 is old,it should have an older Xorg version,maybe you'll need to edit a different config file.

I'd like to emulate the right click mouse button onthe touchscreen,but I have not found any program yet.

Granted this is for Ubuntu 10.04 but there may be some help. I started an earlier thread yet called Toughbooks and Linux based on Mint 8. Ancient history now. SEE THE NOTES in blue on page 1.

Replace TEST in the following with 'Toughbooks and Linux'.


TEST site:forum.notebookreview.com/panasonic - Google Search

Also in the FAQ some earlier Linux threads are referenced. http://forum.notebookreview.com/panasonic/229275-ubuntu-cf-29-a.html

G'luck.

Thanks,

OK, i know that the thread is old but i have solved the problem: Open up a terminal session and paste the code under this:


sudo xinput list

(the sudo option is very important, it will ask you for the root password)

Now you should have a print of the input peripherals, including keyboard and touchscreen, ever device have an ID number next to the name, in the case of my Touch screen panel the number is "11", keep it in mind (or on paper).
Now, write the following code, changing my "11" with the number of your Touch Screen.


sudo xinput set-int-prop 11 "Evdev Axis Calibration" 32 150 3850 330 3850


The last four nuber groups (150 3850 330 3850) are the limits of the panel, I had to adjust them manually, you should do the same to fit your specific panel (i have the 13.3" version).

Now the settings are right, but they are temporary, on the next reboot the original setting are restored, so to make them permanent you have to insert this command in autostart.

I have done this by two ways, the first is by crontab and the second is by System->Preferences->Startup applications.

When it boots up, it will set the correct touch panel dimensions; my panel is a "Fujitsu Lifebook Touchscreen".
