btw. all the example command lines need to be updated since we updated our demoweb instance recently. Also the resolver from the end of this command line needs to be removed:

Your command works for me on Ubuntu 18.04 LTS and Debian unstable. Can you let me know what OS you're using so I can try it out and have a look at where the actual issue is?

Thanks for flagging

I am using debian buster. The new log after your most recent commit is this:

[LWJGL] GLFW_API_UNAVAILABLE error

Well, this is embarrassing. I tried to run glxgears which also failed so I debugged a bit and had to remove some nvidia drivers (I don't have an nvidia card)...

Perfect, the new error is clear enough about what went wrong. Score one for LWJGL.
