First off, thank you so much for a Linux port. I've been holding on X Rebirth anxiously waiting and hoping this day would come. This really made my week.
Now, with that being said...
No joystick support yet. It just feels wrong. I was hoping to dig around and get lucky if I just created an inputmap.xml, but I'm actually pretty burnt from debugging my own code all week and I've got a hunch that there isn't an interface to the SDL libs just yet.
Is there a hack to enable, even if buggy, basic joystick support? If not, as I suspect is the case, is there a timeline for when that support can be expected? I'd like to formally volunteer to test that piece of code as soon as it compiles.
FWIW, I'm running KDE on:
* Ubuntu 14.04
- kernel: 3.13.0-24-generic #46-Ubuntu SMP
* Geforce GT 730
- binary blob: nvidia-331, 331.113, 3.13.0-24-generic, x86_64
and I haven't had any other issues with X Rebirth in the short time I've played with it.
