First the fix, then the explanation.
IF AFTER BIOS CHANGE OR HDD SWAP:
TS does not calibrate.
Cursor motion IS detected in lower right quadrant. (see below near end)
Unit is running Linux of any sort using xorg-calibrator.
In terminal:

Edit minx to 0, maxx to 16000 miny to 0 maxy 16000 and re-boot,set to defaults and [F10].

Run calibrate again and plug in the numbers. (hint: run it enough so that the cursor falls exactly on the red x'es. Usually three times.)

Explanation:
What we have done on machine is create a box with 99-calibration.conf that is 1/4 the screen size. Then, when we attempt to calibrate after a bios change the numbers are out of range (Parameter error). Background: When a unit is first loaded w/OS (Linux, Mint etc.)EVDEV assigns 0 and 16,500+ on the first go round with the calibrator. That's why it works the first time the system is loaded and only shows up later with a bios change.

Please don't get excited here if you have a bad touch panel. This is as mentioned above a sudden change from working to non-working after a bios change.or when swapping a drive between machines. I do it daily. What will be seen is on tapping the first red x (+) the cursor will be seen in the lower corner, 2 inches up and three inches in towards the center on machines using xinput-calibrator.
Actually it can happen on W7(Vista) with a different fix. That's what the reset box is for in tablet calibrator.

Right on man. Maybe Rob will see the value in making this a sticky.

Maybe we should start a 'Linux' section.

I like the idea of a Linux section. Right now, all that info is scattered everywhere.

+1 for a separate Linux discussion. And one of the first stickies in that forum should be the tutorial for using Linux to test the touch panels.

Toughbooks and Linux/Mint as a separate section is an idea I have been thinking about for a while.

Even though I don't use linux as my main os it is my dual boot/second option. I think a linux section would be good.

I just sent Rob a PM about it

Ok guys, Linux has its very own section now. Rob just got it done. If there is other post/threads that need moved send me a PM and I will put a list together and send them to Rob. Rob has been busy and it would be better if just one of us sends a PM to him regarding any moves...thamks

I only could find one other post Linux@Toughbook CF-19 MK3 - minipciGPS - no function here http://www.toughbooktalk.com/viewtopic.php?f=3&t=1378

There is an old Ubuntu 10.10 in the download section.

Thanks Rob,
