The Linux developers at Unity [ Official Site ] have been plugging away on putting SDL2 [ Official Website ] into the Linux builds, and with Unity 5.6 it should be there.Na'Tosha Bard tweeted out that the code for it has landed in "trunk" (their main codebase), so it's all ready to go now. The first beta of Unity 5.6 sounds like it's not due for another few weeks yet, so there's still some time until anyone can test it in the wild.I spoke with Na'Tosha for a bit on Twitter to clear some things up. She said that it enables Unity to remove their own X11 implementation, and they are using SDL2 for window management and mouse, gamepad, joystick and keyboard inputs.Na'Tosha did state that she's not aware of any actual issues being fixed by using SDL2, but some users may see improvements.It will also provide them with the possibility of Mir and Wayland support in future, but they aren't currently on their roadmap yet.This is good for SDL2 as well of course, as any bugs encountered by the Unity team can be reported and hopefully fixed to then improve SDL2 for other developers. The power of open source and all that jazz.SDL2 isn't the only big thing that Unity 5.6 will bring. It's also planned to have their first version of Vulkan support too, and you can find more on that here You can find out what else Unity has planned on their roadmap You can also find the Linux builds of the Unity editor right here on their forum Many thanks to Na'Tosha Bard for replying to me on Twitter about it to clear some things up.
