Can't fully configure my device with current xorg.conf settings.

I'm trying to install Linux on my Android. I'm configuring xorg.conf file to map my devices to Ubuntu and stuck with some special device that I can't find how to configure.

This device has both keyboard and touchpad in one device. To be specific, one event, /dev/input/event8 is both keyboard and touchpad.

I tried to configure this device with the following configuration, where I load one event from two input devices.

Code:

Section "InputDevice"
        Identifier "Keyboard0"
        Driver "evdev"
        Option "Device" "/dev/input/event8"
EndSection
 
Section "InputDevice"
        Identifier "Touchpad0"
        Driver "evdev"
        Option "Device" "/dev/input/event8"
EndSection

However, there are two problems.

First, second InputDevice is ignored. It says in the log that event8 is already configured and second InputDevice will be ignored.

Code:

[   199.965] (**) evdev: Touchpad0: Device: "/dev/input/event8"
[   199.965] (WW) evdev: Touchpad0: device file is duplicate. Ignoring.

Second, evdev only recognizes device as keyboard. When I checked the log, it said

Code:

[   199.962] (II) evdev: Keyboard0: Configuring as touchpad
[   199.962] (II) evdev: Keyboard0: Configuring as keyboard

which seems like setting for this device is always overwritten as keyboard. I found you can force device type(keyboard, touchpad) using InputClass. However, this only works device specific. That is, I can tell this device is touchpad or keyboard, but I can't tell xorg.conf to read this device once as touchpad and another time as keyboard.

Full xorg.conf and log file available:
xorg.conf: http://pastebin.com/LW83x4kX
Xorg.2.log: http://pastebin.com/j8HY2WDx

Thanks in advance.

Hi johny9

I'm not good with adding arguments to that particular (xorg.config) configuration file. Sorry

Here is a video that should help or at leat give you a base knowledge how to put Ubuntu on your Android:-
You'll need a SD Card-
The man mentions that if it doesn't work you may have to install a higher/newer version of the kernel.
