I'm trying to use xming to render software using OpenGl running on the same machine in WSL / windows bash.
This works fine for some really small demos, however once I try something like glmark2, it fails because it seems the OpenGl version is reported incorrectly.
glxinfo | grep OpenGL reports this:
OpenGL vendor string: NVIDIA Corporation
OpenGL renderer string: GeForce GTX 970M/PCIe/SSE2
OpenGL version string: 1.4 (4.5.0 NVIDIA 382.05)
If I let xming run on my internal graphics card (using a laptop), it reports
OpenGL vendor string: Intel
OpenGL renderer string: Intel(R) HD Graphics 4600
OpenGL version string: 1.4 (4.3.0 - Build 20.19.15.4568)
The weird part is the 1.4 in front of 4.5.0 NVIDIA 382.05.
The OpenGl support is definitely at least 3, because a demo using GLSL shaders which require newer OpenGl runs, but the version string is kinda garbage.
The problem you're running into is, that the GLX portion of XMing does support only up to OpenGL-1.4. The part inside the parentheses is the version string as reported by the system native OpenGL implementation. However since XMing lacks (so far) the capability to reliably pass on anything beyond OpenGL-1.4 it will simply tell you "all I guarantee you to support is OpenGL 1.4, but the system I'm running on could actually do …".
Maybe some day someone goes through the effort to implement a fully featured dynamic GLX←→WGL wrapper.
