I have a jailbroken Kindle Touch onto which I've downloaded hawhill's
Kindle VNC viewer (native app, GPLv2). I've managed to get most things working but I'm unable to get
touchscreen input to be detected when the app is running.
My lua config script does detect when I push the home button and exit the app as intended, but nothing is happening if I tap the touchscreen.
However if I run evtest on the kindle, I can see that there are touch events being generated. I imagine there must be a typo in my config file but I'm not familiar with Lua. I've tried everything I can think of and would really appreciate help fixing this bug.
On Linux (raspberry pi 3) I run the following in the terminal:
Code:
sudo ifconfig usb0 192.168.15.2
x11vnc -clip 800x600+0+0 -usepw &
ssh root@kindletouch-usb0
On kindle I run:
Code:
stop lab126_gui
cd /mnt/us/extensions/kvncviewer/
lipc-get-prop com.lab126.powerd preventScreenSaver
lipc-set-prop com.lab126.powerd preventScreenSaver 1

start lab126_gui

you have also the following API functions:

SendKeyEvent( keyCode, pressed )
sends a key event to the rfb server. "pressed" is a bool value
telling whether the key was pressed (true) or released (false)
SendPointerEvent( x, y, buttonMask )
sends a pointer event to the rfb server
