2 touchreens calibration with eGalax driver

freeindy · 10-18-2011, 10:39 AM

Hi,

I have 2 touchscreens (Prolite PLT1931SR) connected my debian 2.6.

The screen is working in 'expanded' mode, i.e i have 2 screens working as one big widescreen. Each screen's touch port is connected through usb:

It finds the driver (egalax) but I seem to get some conflict (i think) with the xorg configuration. In both cases it selects configuration #1. Is that ok?
The xorg.conf (/usr/share/X11/xorg.conf.d/50-egalax.conf) generated by egalax installation looks like:

Code:

Section "InputClass"
        Identifier "eGalax touch class"
        MatchProduct "eGalax Inc.|Touchkit|eGalax_eMPIA Technology Inc."
        MatchDevicePath "/dev/input/event*"
        Driver "egalax"
        Option "Device" "usbauto"
        Option "Parameters" "/var/lib/eeti.param"
        Option "ScreenNo" "0"
        Option "SkipClick" "0"
EndSection

Section "InputClass"
        Identifier "eGalax mouse class"
        MatchProduct "eGalax Inc.|Touchkit|eGalax_eMPIA Technology Inc.|eGalaxTouch Virtual Device"
        MatchDevicePath "/dev/input/mouse*"
        Driver "void"
EndSection

Section "InputClass"
        Identifier "eGalax joystick class"
        MatchProduct "eGalax Inc.|Touchkit|eGalaxTouch Virtual Device"
        MatchDevicePath "/dev/input/js*"
        Driver "void"
EndSection

I have been trying to use eGalaxTouch utility to calibrate them both but without success. Does anyone have a suggestion or howto doc on how I can setup 2 touchscreens in Debian.

Thanks,
Indy

OK. I solved it.

If anyone is interested:

1. Remove 50-egalax.conf from /usr/share/X11/xorg.conf.d/.
2. Generate a new xorg.conf by X -configure.
3. Added following to the xorg.conf:

Code:

Section "ServerLayout"
...
    InputDevice "EETI1" "SendCoreEvents"
    InputDevice "EETI2" "SendCoreEvents"
EndSection

Section "InputDevice"
    Identifier "EETI1"
    Driver "egalax"
    Option "Device" "/dev/usb/hiddev0" #Check /var/log/messages
    Option "Parameters" "/var/lib/eeti1.param"
    Option "ScreenNo" "0"
EndSection

Section "InputDevice"
    Identifier "EETI2"
    Driver "egalax"
    Option "Device" "/dev/usb/hiddev1" #Check /var/log/messages
    Option "Parameters" "/var/lib/eeti2.param"
    Option "ScreenNo" "1"
EndSection

4. Use eGalaxTouch utility to calibrate.
