environment setup for using enigmatoolbox.plotting.plot_cortical?

[Conxz]

When trying to use the plot_cortical function on my linux machine, it was not working. It seems that some setup is necessary. I tried to install opengl libs, but it's still not working. Do you have any suggestions on this issue? Thanks.

Hello!

I'm not sure. This could be a library issue. I'd suggest to ask your sysadmin :)
