I was digging around in the GLFW code a bit before I saw your comment, and the "Arguments are inconsistent" message seems to be how GLFW describes an EGL_BAD_MATCH error code. There's a few places in egl_context.c where
getEGLErrorString
is called that could return that string, but it's probably in_glfwCreateContextEGL
given the "Failed to create context" part of the error quoted.The error handling there (if this is the right place -- I would have also expected "EGL" in the message, but maybe OP dropped it) follows a failure of
eglCreateContext
. The reference documentation for that function here -- https://registry.khronos.org/EGL/sdk/docs/man/html/eglCreateContext.xhtml -- unfortunately doesn't give much detail about the kinds of errors that can happen, but does talk about OpenGL versions so a mismatch on that makes sense; I think this is on the right track.Googling the
OpenGL renderer string: llvmpipe (LLVM 16.0.6, 128 bits)
line from the glxinfo output suggests that's software rendering, so the OpenGL version shown there may differ from what is actually supported by hardware rendering. Is there an EGL equivalent to glxinfo? (eglinfo, maybe?)I'd personally comment out all the
glfwWindowHint
calls and see if a window shows up at all -- then mess with the OpenGL version if needed.
