Here’re the snapshots:
1 Add touch screen support to FirePrime Linux
1.1 Introduction
X11 window system uses evdev input driver to handle touch screen
events. There're mainly two steps to add touch screen support:
1. Add X11 configuration file to use evdev driver for touch screen.
2. Make evdev support touch screen (also emulate right mouse button).
1.2 Configuration
Create file `/etc/X11/xorg.conf.d/10-evdev-gslX680.conf’ with
following contents:
,----
| Section “InputClass”
| Identifier “gslX680 evdev touchscreen”
| MatchProduct “gslX680”
| MatchDevicePath “/dev/input/event*”
| Option “EmulateThirdButton” “true”
| Option “EmulateThirdButtonTimeout” “500”
| Option “EmulateThirdButtonMoveThreshold” “50”
| Driver “evdev”
| EndSection

1.3 Make evdev support touch screen
The original evdev driver does not support Android input touch driver
well. It needs some patches.
Here're the main steps to patch and recompile a new one.
1.3.1 Install build environment and dependencies
------------------------------------------------
,----
| sudo apt-get install build-essentials
| sudo apt-get build-dep xserver-xorg-input-evdev
`----
1.3.2 Fetch, patch, and compile the source code
-----------------------------------------------
,----
| sudo apt-get source xserver-xorg-input-evdev
| cd xserver-xorg-input-evdev-2.9.0/src
| GITHUB=https://github.com/TeeFirefly/xf86-input-evdev/tree/ba37709e2aab50354c9925ca1e975779a16c67dc
| wget $GITHUB/src/emuThird.c
| wget $GITHUB/src/evdev.c
| wget $GITHUB/src/evdev.h
| cd ..
| make -j4
`----
1.3.3 Install the newly built module
------------------------------------
,----
| mv /usr/lib/xorg/modules/input/evdev_drv.so /usr/lib/xorg/modules/input/evdev_drv.so.orig
| cp src/.libs/evdev_drv.so /usr/lib/xorg/modules/input/evdev_drv.so
