Touch Screen - Kind of Works - Any input?

[flipjargendy]

For the past few hours I have been reading forums, trying all sorts of xorg.conf settings and searching out drivers. Out of the box, Debian moves the cursor when I touch the screen and move my finger across it. The only problem is that it doesn't process it correctly. It is moving faster, so it doesn't stay under it. It also doesn't land under my finger when I touch the screen.

I am running a Panasonic Toughbook CF-29.
Driver I am trying: evtouch

Has anyone had success with this laptop?

Here is my current xorg.conf:

I have a CF-18 which is experiencing similar problems. This laptop's touchscreen worked with previous version of kernel/xorg. I am thinking it is my recent xorg upgrade that broke it (currently running X.Org X Server 1.7.5). This was with evtouch.

I have never gotten evdev method to work. If your experience is like mine try evdev instead of evtouch and I think you may get same results.

I have posted to xorg mailing list on this topic. It may help if you added your comments to the thread (assuming it is same issue).

I am in process of trying some live CDs of various distributions to see if one of them works.

Again, touchscreen worked great on my CF-18 at one point (with evtouch).

I was able to resolve this on my system. It may be same issue as original poster so I will add this here as I came across it when researching my issue.

I made a few changes at once so am not sure what addressed it. I am running a Gentoo based CF-18. I upgraded xorg-server to version 1.8. Also, I let the X server detect my input device instead of having explicit entries in xorg.conf. I could have updated other X drivers to other more recent versions.

After doing some/all of the above I noticed that with evdev the touchscreen was tracking differently then previous (although not accurate). I then ran x_input_calibrator and not only did the calibration values "take", they resulted in correct calibration.

Here is snippet of what server generated on startup:

To be clear: I am not using evtouch.

An update... and response...

UPDATE
Touchscreen works and is pretty much calibrated due to the help of someone else on other forums providing an xorg.conf for their Toughbook.

Everything works properly now except the touch pad. The buttons for the touchpad work. I can also tap the touchpad, for use as a button. There is definitely input from the touchpad when I scroll it but the mouse cursor does not move. Instead it switches mouse cursor images (ex. text cursor to arrow).

I have commented certain things out of the xorg.conf and set some from true to false and what not. Nothing has effected the way the touchpad works. yet.

RESPONSE
Is x_input_calibrator something that comes with Gentoo? Thanks for the info!

[flipjargendy]

I have narrowed it down to the "Server Layout" section.

This probably seems obvious. After "touchscreen" or "Synaptics Touchpad" if you put "CorePointer" that will the device that will work. I have tried a few other configurations with no success in making them both work at the same time.

It is not Gentoo specific. I downloaded and compiled it. The forum won't let me include a url. Do a search for xinput calibrator.

In my case udev is finding all the input devices (X.Org X Server 1.8.0)

[flipjargendy]

I am tempted to try udev but have read that it doesn't work with Debian... or am I thinking of evdev?

I am not familiar with Debian but I expect both should work. You may want to research both udev (part of kernel) and evdev (part of xserver). In order for me to get he touchscreen on my CF-18 to work with recent xserver I needed to use both together.

Previously I used evtouch but that is not part of xserver and was problematic for me to get working with recent xserver.
