1 FirePrime Linux 如何增加触摸屏输入的支持

1.1 简介

X11 窗口系统使用 evdev 输入驱动来处理触摸屏的触摸事件。要增加触摸屏的支持，需要以下两个步骤：

• 增加 X11 配置文件，指定对触摸屏设备使用 evdev 驱动。
• 完善 evdev 驱动本身对触摸屏的支持，并加入模拟鼠标右键的支持。
  

1.2 配置

创建新文件 /etc/X11/xorg.conf.d/10-evdev-gslX680.conf ，加入以下内容：

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 完善 evdev 驱动的触摸屏支持

系统的 evdev 驱动无法很好地支持安卓的触摸屏输入驱动，需要打补丁并重新编译，以下介绍详细步骤：


1.3.1 安装编译工具环境和相关的信赖库

sudo apt-get install build-essentials sudo apt-get build-dep xserver-xorg-input-evdev

1.3.2 提取源码、打补丁和编译

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 安装编译好的模块

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

重启系统生效。

Support Need:

When I run to this step: make -j4
It show error: make: *** No targets specified and no makefile found.  Stop.

Did I lose what steps ?

zadeh

update:

add:sudo  ./configure
then make -j4 is ok

I finish all steps, but still failure
my "10.1寸LVDS顯示屏 Firefly-RK3288 FirePrime（拍下三天後發貨）" still not work,
at Firefly-RK3288.

Is the code support RK3288?

Thanks your replay!
" 1.The name of official firmware to support the AUO LVDS Display Module with the words "B101EW05", such as Firefly-RK3288_PAD_B101EW05_Android4.4_201501281108.7z
2. After updating the code, follow the instructions in the patch, and support the use of 10.1-inch screen.Patch (with captions) "

but "Firefly-RK3288_PAD_B101EW05_Android4.4_201501281108.7z" seems is the android version,
do you have ubuntu's patch?

linux kernel patch is the same as android kernel.
