Touchscreen input X11

profecie · 05-19-2015, 10:38 AM

Hello,

I try to deploy CentOS 6.1 on embedded system with touchscreen working on serial port with driver developped and tested on many linux like Ubuntu or Debian
command:

Code:

cat /proc/bus/input/devices

display the touchscreen device

I: Bus=0013 Vendor=002a Product=0000 Version=0110
N: Name="eTurboTouch Serial TouchScreen"
P: Phys=ttyXR4/serio0/input0
S: Sysfs=/devices/serio2/input/input9
U: Uniq=
H: Handlers=mouse2 event6
B: EV=b
B: KEY=400 0 0 0 0 0 0 0 0 0 0
B: ABS=3

and

Code:

cat /dev/input/mouse2

or

Code:

cat /dev/input/event6

display the events correctly.

But nothing happened and the cursor doesn't move.I tried to modify xorg.conf but without success

Can you help me?
Thank you in advance

Mine is a Dell XT2 Touchscreen that interfaces through internal usb vs your way

working on serial port

Though being detected, which is good. No inputs is kinda hard to trouble shoot.

If you have a recent udev. I guess you can try

Code:

sed '/Sysfs=/!d; s/.*=//' /proc/bus/input/devices | xargs -I '{}' udevadm info --path='{}'  | grep TOUCHSCREEN

Code:

xinput list | grep -i touchscreen

I probably won't be of much help because I find my driver used for my touchscreen through a usb command

Code:

dmesg | grep usb

All I can figure is to try

Code:

dmesg grep | less

after you try and move the mouse cursor and cross your fingers it tells you something useful.
My feeling the is the serial port is the roadblock for accepting inputs.
Mine works with the wacom type of pen with mouse buttons on it and also my finger is accepted as a input device.

Our touchscreens are probably miles apart as far as who made them and how.
As far as /etc/X11/xorg.conf goes
To me, the best thing is to have no xorg.conf at all and let Xorg find and setup the touchscreen itself.

But if you have a line in xorg.conf that says

Code:

Option "AutoAddDevices" "false"

change it to

Code:

Option "AutoAddDevices" "true"

and cross your fingers again. A logout or reboot may be required. I don't know.
I am just a Linux user scooter tramp with some home grown skills so that is the best I can suggest.

Thank you for your reply!This is the reply of the differents commands

Code:

sed '/Sysfs=/!d; s/.*=//' /proc/bus/input/devices | xargs -I '{}' udevadm info --path='{}'  | grep TOUCHSCREEN

eturbo serio1: eTurboTouch Touchscreen, fw: 1.10.00
input: eTurboTouch Serial TouchScreen as /devices/serio1/input/input6

I can also see coordinates(X Y) that i trace in the driver when i click on the screen

is a key here I think that will unlock the no input thing.
That is missing somewhere maybe.

wish I knew more about touchscreens. I wonder if you have mlocate or locate or some other search tool that
you can use to find in text files the line

Quote:

input6

or

Quote:

/devices/serio1/input/input6

which I think should be serial maybe instead of seriol.

Also. I use the inxi script when I wish to describe what I am running in a Linux forum.
Like this Atom Netbook with a touchscreen also that I own besides the Dell I mentioned earlier. Where the touchscreen is a older model but works also just fine. But is internally usb connected.

That's nice. You need to post such things (readouts) so other members besides me respond to your thread. I am going to be unavailable all day as I have to go fix motorcycles which is how I make my money.

Good Luck with it. Rok
