KALI-PI Launcher
   Simple touch menu for Raspberry Pi projects using a 3.5" (480x320) or 2.8" (320x240) touch screen based on garthvh's original project.

   Thanks to JPearn for porting it to 2.8" and to ArmyGuy255a for cleaning up the code and improving the layout.

   It runs as a python script in the framebuffer without needing a desktop environment.

   This menu is the default launcher in Sticky Finger's Kali Pi

   I was after an easy way to launch X Window on either the TFT screen or through HDMI without the need for massive reconfigurations. I came accross garthvh's project featured on Adafruit and used it as basis for this project.

Install and use
   git clone https://github.com/re4son/Kali-Pi (Downloa Kali Pi lancher)
   cd Kali-Pi
   sudo ./menu (Run Kali Pi launcher)

   customise the file "menu" to match the path, define the screen size, etc.
   cusomise the scripts to suit your needs

   Important: Pygame is broken on on Debian Jessie. I'll explain below how to fix it.

Layout
   Start Screen

      All functions are self explainatory. After exiting and application, the screen returns back to the last menu.

      The "Screen Off" function launches the python script "menu_screenoff.py", which uses the RPi.GPIO module to turn the screen off. You can turn it back on by pressing anywhere on the screen.

      Using the ">>>" button, we can scroll to the next screen, namely "menu_kali-2.py". The buttons allow us to stop and start services. The button changes to green when the service is running Press the button again to stop the service.

   menu-pin.py: The variable "KPPIN" in the file ~/menu can be set to "1" to enable PIN authentication to hide the menus from spying eyes

   Screensaver
The screensaver can be enabled by setting the variable KPTIMEOUT in the file "./menu". Set it to the number of minutes after which the screensaver should kick in (very approximate value). Use 1 for 1 min, 0.5 for 30sec, etc. Touch anywhere on the screen to wake the system up. When KPPIN is set, the screen will return to the PIN menu after waking up.

   Run menu at startup
      The preferred method to run this script on startup is to add it to the end of ".profile": nano ~/home/.profile
      And add the following line to the bottom of the file: sudo /home/pi/Kali-Pi/menu

Fix Pygame on Debian Jessie
   The package "libsdl1.2-15-10", which ships with Debian Jessie, breaks pygame. To make it work we have to revert back to "libsdl1.2-15-5" from Wheezy.

   The quickest way is to comment everything out in your /etc/apt/sources.list and temporarily add:
      deb http://archive.raspbian.org/raspbian wheezy main contrib non-free

   Import the corresponding keys:
      deb http://archive.raspbian.org/raspbian wheezy main contrib non-free
      gpg -a --export 9165938D90FDDD2E | sudo apt-key add -

   Remove the offending package and replace it with the working one:
      sudo apt-get update
      sudo apt-get remove libsdl1.2debian python-pygame
      apt-get install libsdl-image1.2 libsdl-mixer1.2 libsdl-ttf2.0-0 libsdl1.2debian libsmpeg0 python-pygame
      sudo apt-mark hold libsdl1.2debian

   Restore "/etc/apt/sources.list" to it's original state.
   That's it. Pygame is fixed :-)
