OK.... the answer is:
download and install (in ubuntu software center) "xinput_calibrator" ... then 'run' xinput_calibrator
.... click on the 4 x's that appear and your are calibrated...
you may have to do this everytime you boot up, but im sure there is a fix for that... im running cf29H... had same issue... its fixed now...

The touch screen on these models do not have a calibration setting. They work or they don't. If it not working properly you can try uninstalling the drivers for the touch screen, then reboot. The machine will find the touch screen and reinstall the drivers automatically. Also check for any updated drivers at Panasonic's support site. Then check the connection for the touch screen, the touch screen has a separate connection than the screen, and it may have worked loose or have a little dirt or corrosion built up. If this doesn't work, then I'm afraid that the touch screen may be wearing out, nothing you can do for this.

How do enable my touchscreen?


This is one link that shows how in pdf (however if you provide your exact model and operating system, you can get a clearer answer) https://www.lenovo.com/shop/americas/content/user_guides/a720_ug_en.pdf
touch screen starts on page 12
2.1 Touch Screen Calibration Prior to first use or whenever the touch screen reacts in a different place where you are touching it, start the calibration program. The procedure is as follows: 1. In Windows 7, Select "Start" - "Control Panel". 2. In Control Panel, select "Hardware and Sound". 3. In "Hardware and Sound" window, select "Tablet PC Settings". 4. In "Tablet PC Settings" dialogue, click "Calibrate" button. 2.2 User Gesture Instructions for the Touch screen The Touch screen supports single touch and rotational movements, enlargement and reduction multi-touch operations, and the user can transmit position information to the computer via touch. The touch screen uses a very low pressure movement recognition method, which only needs the finger to move lightly on the computer display screen or make a simple hand gesture to be detected by the main computer processor.

TOUCH SCREEN NOT WORKING

DO NOT OPERATE AS TOUCH PANTLLA
Touchscreen computers and handheld devices are the newest wave of technological gadgets as of 2010. While these devices function impressively, they can malfunction just like any other technical device. Troubleshooting the touchscreen is simple and often will correct any issues.

Identify how the screen is behaving. A touchscreen will malfunction in one of two areas--sensitivity or position. If you touch the screen and the cursor is not centered on your finger, this is a position error and requires recalibration of the screen. If you touch the screen and it does not register your touch without pressing hard, this is a sensitivity error. If you touch the screen and nothing happens, this can be a sensitivity error or a malfunctioning screen. Calibrate the screen. For all main errors, calibrating the screen will correct the issue. Every device has a different method of calibration but can usually be found under a "Tools" or "Diagnostics" menu option. Reload the device. For handheld devices, remove the battery and let the device rest for no less than five minutes. For computer or computer system devices, power down the device, disconnect the touchscreen device from the computer and remove any power cords to it. Allow the device to rest for five minutes. Reattach the device or reinstall the battery and power up the device. If issues persist, reload the software for the device. For handheld devices, do a full wipe of the device and return it to factory specifications. For add-on devices to a computer or computer system, uninstall the device and reinstall the drivers. If reloading, registering or calibrating the device does not work, consult the manufacturer for possible warranty replacement options.

Cf-28


Hey, sorry bout that, for some reason I had cf27 in my head. You're right on the Windows calibration, but with the Linux system there isn't much out there. Here's a forum I found on the subject. You might read over it and see if it will work for you. There is a section on the touch screen towards the bottom.

HP problem with touchscreen Hello, did you solve your problem with touchscreen. I've had the same problem yesterday. could you help me please? thanks.


When you first begin using the PC, or if you have intermittent problems using the touch screen, you should calibrate the touch screen and set up the screen preferences.


NOTE: The touch screen works best if only the stylus, and not your hand, is touching the screen. If you rest the palm of your hand on the screen for comfort, you will have to press the pen more firmly onto the screen.

Touch screen stopped working


Hi Everyone

I have the solution to the touch screen problem. You need to get the support and strip down document for yout touch screen from HP.. for instance the one for the tx1000 series is c00853874.pdf

you will need another machine or to print the pages required to strip your machine all the way down to removing the monitor, and the surround on the screen.

the document is step by step...label the screw etc, you'll be fine...even if you have never done it before.

the result is the terrible build quality of the machines. the ribbon access cables for the webcam, and for the touch screen are poorly installed.

I found that my touchs screen access cable was not actually properly installed at all, and was only barely contacting when i received the machine.

my touch screen is working properly, you need to be gently with everything, the circuit board that the webcam and the touch screen connect to is directly behind the screen..

you must strip the screen down, and then lift the glass... there are 4 screws around the edges of the glass when you have it stripped down... once you lift the screen up.. there is a circuit board on the rear of the top of the plastic screen back. the are connectors going into this...for the quick access buttons around the screen edges...the webcam,.. and the touchscreen.

i have to say i just discussed this with a guy called GINO on Hp online support...and he doesnt care that this is the solution...or that there has been a manufacturing fault since day on.. they never plugged the cables in properly.

email me if you get stuck...
