Unrecognized OpenGL version when launching start_app()

[stefanocasali984]

Hi,

I've installed all the dependencies listed here : [http://bluebrain.github.io/RTNeuron-3.0/old/compilation.html], then downloaded the rtneuron AppImage and succesfully run it.
However, when I type

start_app()

then the following error is returned:

Unrecognized OpenGL version QOpenGLWidget: Failed to make context current composeAndFlush: makeCurrent() failed composeAndFlush: makeCurrent() failed composeAndFlush: makeCurrent() failed

A window actually prompted but was totally black and not reacting to any input.
I've tried to reinstall OpenGL using the following commands:

sudo apt-get install mesa-common-dev libgl1-mesa-dev libglu1-mesa-dev freeglut3-dev

but nothing changed.
I'm working on Ubuntu 18.10
What I'm doing wrong / missing?

Thanks in advance for help!

Are you using Wayland or X.org? Because I doubt it will work on Wayland.

I'm using X.org.
