SOME devices can not run Unciv because software OpenGL mode is not allowed.
Put this code System.setProperty("org.lwjgl.opengl.Display.allowSoftwareOpenGL", "true");
The problem will be solved. This will allow libgdx to run as software openGL mode.

Yes, I'm asking which devices. Is this a software problem, certain OS's? A hardware one?

I think this is a hardware problem.Libgdx requires at least OpenGL 1.5 on the desktop.But SOME people don't know how to update the OpenGL.So I suggest putting the code.

1st generations Intel HD Graphics running under Windows 10 with Java 8u60 and newer. LWJGL/lwjgl#119
Downgrading java to 8u51 solved problem for few people in discord.
This exception also can be caused by outdated or incompatible driver.
There was 1 person in discord with this problem recently. He had intel B960 and windows updated drivers to 9.17.10.4459 (Windows 10 does not have official GPU support for Sandy Bridge); downgrading drivers to 4229 - latest compatible with his intel GPU - solved the problem
