create_standalone_context() fails in moderngl5

[alexgrabner]

I just upgraded from release 4.2.2 to 5.0.4 and the standalone context creation is broken for me. I reverted to 4.2.2, where it works. Thanks for help in advance.

Ubuntu 16.04 64bit
Python 3.6.4

Input

import moderngl
ctx = moderngl.create_standalone_context()

Output

   3120     ctx = Context.__new__(Context)
-> 3121     ctx.mglo, ctx.version_code = mgl.create_standalone_context(settings)
   3122     ctx._screen = None
   3123     ctx.fbo = None

Error: cannot choose a visual info

Thank you for the report.

There were 3 implementation for standalone context on linux in ModernGL5 (X11 EGL OsMesa) unfortunately only X11 supports OpenGL 3.3+ so I restored the implementation from ModernGL4 that supports only X11.

python -m pip install "ModernGL>=5.0.5"

Thanks for the quick feedback, but the issue is still there for me. Any suggestion? Thanks.

X.Org version: 1.18.4
OpenGL version string: 4.6.0 NVIDIA 390.30

Input

import moderngl
print(moderngl.__version__)
ctx = moderngl.create_standalone_context()

Output

5.0.5

This is the only remarkable difference: f34af6a

please test with the master now:

python -m pip install https://github.com/cprogrammer1994/ModernGL/archive/master.zip

The problem does not occure on my computer. Please test it. It will help me a lot.
