Touchscreen Calibration and Repair Catch22 (LINUX)

#1 Post by SHEEPMAN! »

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:

Code: Select all

sudo gedit /etc/X11/xorg.conf.d/99-calibration.conf
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.
Fair for you/ Fair for me.
I chose to NOT be organized.

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

Maybe we should start a 'Linux' section. :)

Life's Journey is not to arrive safely at the grave in a well preserved body, but rather to skid in sideways totally worn-out shouting 'Woo Hoo! What a ride!

Motorsports - the only real sport. If it doesn't have a motor, it is just a game.

There is always something waiting at the end of the road, if you are not willing to see what it is, you probably shouldn't be out there in the first place.

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.

:D

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.

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

There is an old Ubuntu 10.10 in the download section.

Thanks Rob,
