Hi,

I have a touchscreen from 3M. It seems to have drivers for linux:
http://solutions.3m.com/wps/portal/3M/en_US/3MTouchSystems/TS/TechnicalInformation/TouchDrivers/

but I can only choose between different RPM downloads.
Can I use these drivers and/or software (if any) in gentoo?
How?


thanks

Hi,

You don't tell the type of connection (serial, usb).

But for the kernel you have the driver in the
Device Drivers --->Input device support --->[*] Touchscreens ---><M> USB Touchscreen Driver (for usb)
or <M> MicroTouch serial touchscreens (for serial)

Yes it is for 3M. At least the usb driver. And when it was serial it was named MicroTouch.

This driver (when loaded) create a evdevice that is used by xf86-input-evtouch.

So
Code:
emerge x11-drivers/xf86-input-evtouch


And you need something like this in the xorg.conf
Code:

   Section "InputDevice"
      Identifier "touchscreen0"
      Driver "evtouch"
      Option "Device" "/dev/input/event3"
      Option "DeviceName" "touchscreen"
      Option "MinX" "62"
      Option "MinY" "1910"
      Option "MaxX" "1966"
      Option "MaxY" "45"
      Option "ReportingMode" "Raw"
      Option "SendCoreEvents"
   EndSection

Depending on screen.

Ref:http://linux.chapter7.ch/touchkit/mini-howto.txt

P.S. I don't have any touchscreen.

sorry, I forgot to mention the connection.

it's a serial connection. I'm currently using the sabayon kernel. from what I can see in the config, I think the touchcreen is supported and mircotouch is enabled.
I'll install the tool and see if I can get it to work in the weekend.

thanks already for pointing out this application.

Johan

OK, 3M Microtouch touchscreen serial.

Then you only have to
Code:
emerge xf86-input-microtouch


And calibrating tool
Code:
emerge x11-misc/touchcal


And insert something like this into the xorg.conf (if you connect it to ttyS1)
Code:

Section "InputDevice"
        Identifier "TouchScreen"
        Driver "microtouch"
        Option "Type" "finger"
        Option "Device" "/dev/ttyS1"
        Option "ScreenNo" "0"
        #subtracting shifts cursor right
        #adding shifts cursor left
        Option "MinX" "150"             #left
        Option "MaxX" "16233"           #right
        #subtracting shifts cursor up
        #adding shifts cursor down
        Option "MaxY" "200"             #Bottom
        Option "MinY" "16483"           #Top
        Option "SendCoreEvents" "yes"
EndSection


To test the comport you may

cat /dev/ttyS0 (or ttyS1)

then touch the screen and it would be some garble in the terminal.

And in the serverlayout section enter
Code:
InputDevice     "TouchScreen"


It work like a mouse so you only have to have the comport working in the kernel.

Regards

Hi

Am trying to set up a Point of Sale terminal to run Gentoo.
It has a built-in touchscreen (LCD) monitor. It's made in China and branded as "POS terminal" ...

I figured I should use x11-drivers/xf86-input-evtouch, but that seems to demand a lower version of xorg-server than 1.5:

Code:

equery depgraph x11-drivers/xf86-input-evtouch | grep xorg-server
 `-- x11-base/xorg-server-1.3.0.0-r6
                                                                                `-- x11-base/xorg-server-1.5.3-r5 [ X ]


When I tried to install it, I got blocking with evtouch wanting 1.4 to pull in 1.3, and libpciaccess wanting 1.5.

So... is it possible to install x11-drivers/xf86-input-evtouch with xorg-server 1.5, or should I be using a different driver?

thanks, Ian

You can also install rpm-packages.

emerge rpm

I had to do that in order to get my Brother HL-2140 to work.

Moved from Kernel & Hardware to Unsupported Software.
