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.
