slackware 13.1 flybook touch screen

[zuliani71]

Hi,
I've just installed Slackware 13.1 on my flybook V33i. Most of the hardware has been recognized and now I'd like to use the touchscreen. I've compiled and loaded the touchscreen module penmountlpc 1.1. I've also downloaded xf86-input-plpevtouch-0.5.0 and installed with the command:
./configure --prefix=/usr/X11R6 && make && make install (I've X11R6 and not X11R7).

After that, as slackware use HAL to config X11 and doesn't use a xorg.conf as default, I've started xorgsetup to create a good xorg.conf for my laptop. startx, with that new xorg.conf, gives me a stable and well configured machine (both for video, mouse and keyboard). Adding the Section "InputDevice" and the Section "ServerLayout" suggest at: http://www.plop.at/en/touchscreen.html
gives me a working desktop but mouse and keyboard don't work. Even the pen on the screen has no effects. On the web I've found another config to use inside xorg.conf:

Section "InputDevice"
        Identifier "touchscreen"
        Driver "plpevtch"
        Option "Device" "/dev/input/event7"
        Option "DeviceName" "touchscreen"
        #Option "MinX" "47"
        #Option "MinY" "49"
        #Option "MaxX" "982"
        #Option "MaxY" "981"
        Option "Calibrate"
        Option "Debug"
        Option "ReportingMode" "Raw"
        Option "Emulate3Buttons"
        Option "Emulate3Timeout" "50"
        Option "SendCoreEvents"
        Option "MoveLimit"  "2"
EndSection

and for the "ServerLayout" I've used:
     InputDevice        "touchscreen" "SendCoreEvents"


With that config I've the same results (mouse and keyboard don't work) but the pen is alive. It's not calibrated but when I touch the screen the cursor moves in a new position (no tracking anyway). Can you help me?


Thanks in advance

David

hi,
don't use plpevtch. the default xorg evdev driver should work fine. calibrate with http://www.freedesktop.org/wiki/Software/xinput_calibrator (thanks to manuel u.)

Hi Elmar, thanks for answering me.
I've downloaded and untar the xinput_calibrator, I run ./autogen.sh and make, it seems there are no problems with that.
When I run the xinput_calibrator I get "No calibratable devices found" What to do?
I've tried with and without xorg.conf (if I remove xorg.conf slackware uses HAL).
When I use the xorg.conf I change the line

Driver "plpevtch"

into

Driver "evdev"

Both tests gave me the same result.
Bye

Hi Helmar do you have any suggestion for me.

Thanks

[Elmar]

Ok, what about the error:
"Error: No calibratable devices found." Any ideas?

Ok, what about the error:
"Error: No calibratable devices found." Any ideas?

First: even if not calibrated, the touchscreen should respond to the input in some way. Do you see any notification on the output of dmesg?

Are you sure the kernel module is loaded?

[zuliani71]

Hi Helmar,

after a more careful check at dmesg I've found the right penmountlpc entry;
PenmountLPC TouchScreen as /devices/virtual/input/input8

I've changed the lines inside my xorg.conf like this:
        Option "Device" "/dev/input/event8"
and after that I was able to use the xinput_calibrator.


I've 2 more questions
a) which the best starting script/place to put the xinput command with configs coming from xinput_ccalibrator?

b) now I'm trying the pen and, after using a manual xinput run from the shell, the cursor goes under the tip after I touch the screen, Anyway I'm not able to slide the cursor together with the tip (just tapping the screen works). Can you suggest me something?

[Elmar]

hi,

disable xorg start
unload penmounlpc
use "modprobe penmoutlpc debug=1"
tab the four screen corners
run "dmesg > dmesg.txt"
and post the dmesg.txt

[zuliani71]

Hi Elmar,

how to disable xorg?

David

[Elmar]

i am no slackware user but try "init 3"

[zuliani71]

Ok Elmar so I need to work in a so called "TEXT MODE", I think it's the same to press CTRL-ALT-BACK SPACE, Is it right?

[Elmar]

yes

[zuliani71]

Ok Elmar, this is my sequence
a) disabled xorg (I worked in terminal or text mode, no graphic)
b) from the console I've unloaded penmounlpc: rmmod penmountlpc
c) Then I've reloaded penmount as you told me:  modprobe penmoutlpc debug=1
    unfortunately that command doesn't work, it gave me: FATAL: Error inserting penmountlpc (/lib/modules/2.6.33.4-smp/extra/penmountlpc.ko): Unknown symbol in module, or unknown parameter (see dmesg)
d) I've tried the commnad modprobe penmountlpc `debug=1` and I've had no more error messages (so I think it has been loaded corrrectly)
e) I've tapped the 4 corners of the display with the pen (the display reacts to the tapping)
f) I run "dmesg > dmesg.txt" and the dmesg output is here attached

I've two questions
1) why the "modprobe penmoutlpc debug=1" doesn't work? I've used a differenet one
Is it correct the comand "modprobe penmountlpc `debug=1`"

[Elmar]

    unfortunately that command doesn't work, it gave me: FATAL: Error inserting penmountlpc (/lib/modules/2.6.33.4-smp/extra/penmountlpc.ko): Unknown symbol in module, or unknown parameter (see dmesg)

i forgot the "n" in penmountlpc

Is it correct the comand "modprobe penmountlpc `debug=1`"

yes, its correct

which version of penmountlpc do you use?

[zuliani71]

Elmar

I know you forgot the n in your command so I've corrected it but anyway if I use:
modprobe penmoutlpc debug=1 it doesn't work.
At the end the right command is: modprobe penmountlpc `debug=1`

did you take a look at my dmesg.txt?

[Elmar]

currently i cannot test the penmountlpc driver on my flybook, but the ' should be not required for the parameter.

i looked at the dmesg.txt but i saw no debug info. which penmountlpc version do you use?

[zuliani71]

I use penmountlpc ver 1.1

[Elmar]

that version does not have the debug parameter

use the penmountlpc driver from http://download.plop.at/files/flybuntu/flybuntu-development-20080922.tgz

[zuliani71]

Ok, downlaode and installed, now the dmesg can track the debugging. Attached yoy can find the new dmesg.txt

Hi Elmar did you take a look at my log?

Bye

David

[Elmar]

yes

the driver reads the data from the touchscreen, but there is a problem with the event handler. currently i cannot say more. i have to do some tests, but i have no time now.

may be it's the evdev that isn't working properly. I've used plpevtch as I told you but the keyboard and the mouse don't work with that.

David

[Elmar]

hmm, yes, maybe its a problem with evdev. maybe my plpevtch is the solution, but  i had no time to fix the conflict with the keyboard and mouse.

i have to install the environment you use to find a solution, but bug searching is time expensive

[zuliani71]

Ok, may be we can work together. I've the system up and running and you could direct me. It'll be a slow process but it's better than nothing.
