Having an issue with the joystick events. At some point (I can’t
determine when) joystick support in my game stopped working on Linux.
I checked other programs and it works just fine. I tried upgrading SDL
(I was still using 2.0.0) and that didn’t work. I used printf to log
the events and it turns out I only get the button release events (not
the press events and not the axis events).
Any idea of what may have gone wrong?
I’m using SDL in Linux too. These events have worked fine for me for a
long time. Currently using hg rev 8086. Could it be a problem in your
device support or elsewhere in Linux?–

I explicitly stated I looked other programs to see if something else
had broken and the joystick worked just fine.

Does that mean other SDL 2 programs?

Didn’t check other SDL2 programs, I checked one with SDL 1.2 though.
Also just checked my game on Windows and it works just fine there
(both SDL 2.0.0 and 2.0.1) so the issue is specific to Linux.

Have you tried compiling the SDL2 tests found in the official source distribution under the test directory? You will find an example called testjoystick that can be ran. Be sure to pass your joystick ID as the first argument (probably zero) – “testjoystick 0” works in my case.
Hopefully this helps to pinpoint the source of the problem.

Updated Ubuntu distro to 13.04, didn’t help.
Checked the test program. Only button release events are reported at
all, none of the other events is. SDL_JoystickGetAxis and
SDL_JoystickGetHat seem to work, though. Weird o.O
By default SDL will only send events while your application has focus.
There’s a hint to enable events all the time:
SDL_HINT_JOYSTICK_ALLOW_BACKGROUND_EVENTS

Um, but I don’t get events while the game has focus (and doesn’t
explain why do I get two of the events: added and button release)…

From the… overwhelming response, I’d say that everyone is cleanly
divided into the “don’t have this problem” or “have no idea what
causes this problem” camps.
Have you tried a simple X11 (I think you said earlier that you’re
using X?) test app to see if you can duplicate the problem there? How
about copying the SDL2 X11 code into a custom app, and slowly cutting
out pieces until you get a least-complexity bug demo?> Date: Sat, 18 Jan 2014 17:49:20 -0200
