Sam Lantinga aaec90e5c5 Fixed bug 4789 - Linux accelerometers no longer available as joysticks 
Daniel Drake

A long time ago, it was possible to play neverball on Linux using the accelerometer found in HP laptops.

The kernel exposes the accelerometer as a joystick (/dev/input/jsX) as well as an evdev device (/dev/input/eventX). I guess it worked fine when SDL was using the js interface, but then stopped working here: http://hg.libsdl.org/SDL/rev/fdaeea9e7567

Looking at current code which uses udev to discover joysticks, it looks for the udev tag ID_INPUT_JOYSTICK.

However udev's internal input_id logic specifically tags accelerometers as ID_INPUT_ACCELEROMETER and nothing else.

This looks like a good fit for SDL_HINT_ACCELEROMETER_AS_JOYSTICK.

Simple DirectMedia Layer is a cross-platform development library designed
to provide low level access to audio, keyboard, mouse, joystick, and graphics
hardware via OpenGL and Direct3D. It is used by video playback software,
emulators, and popular games including Valve's award winning catalog
and many Humble Bundle games.

More extensive documentation is available in the docs directory, starting
with README.md

Enjoy!
