How to make Seiko-LCD detect "tap" (and interpret it as a click)?

haryono — Thu, 03 Jan 2013 23:12:57 GMT

Dear all,

I am using i.MX53 QSB with Seiko-WVGA LCD, running Ubuntu.

It responses to the touch (it repositions the mouse pointer to the location where I touch).

However, when I tap a location, it doesn't detect it as a mouse-click.

Did I miss something here?

Btw, I haven't calibrate the LCD, could it be the case of this?

I don't know how to initiate the calibration. I tried to add "calibration" at the end of bootargs, but it doesn't help.

Thanks a lot.

Hary

Please read the 6.1 How to support Touch screen in Ubuntu. Although it is for i.MX53SMD, you may take it for reference. Also, you can try to delete the "pointercal" file. So it will run ts_calibrate again.

Hi Jimmy,

I got a blank screen after following the instruction in section 6.1

I tried to eliminate to see where the problem is, and finally I found that it's because of the xserver-xorg-input-evtouch package.

Without that package but with everything else mentioned in that tutorial, it works as before (display is fine, no tap detected).

So, any idea?

P.S.: With that package installed, even when I restore back my xorg.conf to the original one, I still got blank screen.

Hi Daiane,

Don't worry about the delay. I got blank screen, and after some elimination steps I found what cause it, but don't know the solution (please refer to my reply to Jimmy above).

Thanks.

Btw, I did "xinput list", and I got a message saying that xserver is not running.

So, somehow with that package it crash my xserver.

I got the package from:

https://launchpad.net/ubuntu/lucid/i386/xserver-xorg-input-evtouch/0.8.8-3build1

Or maybe....should I got it from the image bundle for the release?

Do you know the location of this file in the image bundle for the release?

Thanks a lot.

Do you know there is a re-work list to be done on some imx53qsb revision in order to get touchscreen working?

Re: How to make Seiko-LCD detect "tap" (and interpret it as a click)?

haryono — Thu, 10 Jan 2013 18:02:15 GMT

Hi Daiane,

Yes, I know there is a re-work list.

But my touchscreen responds to touch (mouse pointer moves to the area where I touch). The only problem is when I tap, it doesn't recognize as mouse click.

Does this behavior indicate that it requires re-work?

Hi Jimmy,

I don't know how to check Xfbdev setting in startx. Could you please tell me how do I check it?

Thanks a lot.

Re: How to make Seiko-LCD detect "tap" (and interpret it as a click)?

jimmychan — Fri, 11 Jan 2013 04:03:27 GMT

'startx' is script file, you can type "find . -name startx" in the root directory to find where is it.

Re: How to make Seiko-LCD detect "tap" (and interpret it as a click)?

daiane_angolini — Fri, 11 Jan 2013 18:59:52 GMT

Could you test it using evtest?

I´m not sure, but I remember I have already face the same problem some time ago (taping not working on 53QSB).

WHen using evtest I was able to see pen moving, but the tap event was not recognized. It was caused by a mismatch of linux version and udev / event handler.

Please, let me know the results.

Hi Daiane,

My SEIKO LCD board is Rev B, does it need rework? Where I can find what rev need rework?

So, the symptom when it need rework is that it won't respond to tap, but mouse pointer will still move?

Btw, before I test it using evtest, should I install the evtouch driver first?

But then when I install the driver, my LCD screen went blank.

Re: How to make Seiko-LCD detect "tap" (and interpret it as a click)?

haryono — Fri, 11 Jan 2013 23:36:49 GMT

I assume that line you mention (xfbdev....) would be added automatically to startx after I install the evtouch driver, is that correct?

When I check startx, (it's in /usr/bin), I didn't find xfbdev line you mentioned.

So, should I install the evtouch driver first and then check startx?

My screen went blank after I install evtouch driver though, so it's hard to edit startx. Any idea what's the best way to edit it without screen? Editing it via serial terminal is hard.

Aside from that, what should that line be?

Re: How to make Seiko-LCD detect "tap" (and interpret it as a click)?

daiane_angolini — Mon, 14 Jan 2013 12:32:55 GMT

As I remember, LCD board does not need rework.

Look, I don´t have ubuntu experience, I only use pure linux environment. I don´t think you need to install touch screen driver, it must be included in kernel source code for your board.

Hi Hary,

What Ubutu version are you using?

Did you roll your own Ubuntu version with "linaro media tools" or are you using a formal Freescale Ubuntu release?

Which kernel version are you using?

Hi Adrian,

I'm using formal Freescale Ubuntu release (the one that shipped with i.MX53 QSB in the micro SD card).

The kernel I am using is:
