groovyarcade and arduino joysticks : strange issue

[samguili]

Hello,

i have a problem with advmenu and groovymame : i cant launch a game in advmenu and i cant configure groovymame : the focus is moving constantly, it’s like an arrow key is pushed forever.
This issue disappear when i unplug the two arduino uno serving as an interface between joysticks-buttons and the motherboard.
However, those are working very well in game. I tested it in a manjaro live usb where i installed qmc2 and sdlmame and it worked flawlessly.
So i dont know where the issue could lie, maybe in the sdl library ? When i remove sdl in advmenu.rc to disable the joystick the focus stopped moving.
I tried to compile advmenu from sources on manjaro live usb and the problem came back.
The arduinos are sees by the system as a gamepad openchord x rmit exertion game labs unojoy joystick (project unojoy).

My setup : Groovyarcade 2016-07 32 bits.
Hardware : CPU~Single core Intel Pentium 4 (-HT-) speed~2992 MHz (max) Mem~262.5/2012.8MB HDD~84.4GB

thanks

a clue : when i tried to set up attract-mode to see if the problem was similar, i saw that the events always send to the system are : mouse left+mouse wheelup. So it would seem that the joysticks are messing up with the mouse (wich is not plugged).
The question now become : how to disable the mouse in GA ? I believe that when this is performed the issue will disappear.
I saw in this thread http://forum.arcadecontrols.com/index.php?topic=139191.0 that this file :

Code: [Select]

/etc/X11/xorg.conf.d/50-joystick.conf should be deleted but it's nowhere to be seen in my system.

any help apppreciated, thanks

Workaround in case one is deseperate to solve that issue :
- install lubuntu
- install attract-mode
- set autostart for attract-mode
- set shutdown with power button
- compile groovymame
- enjoy !
