I am trying to install a software to use with Ubuntu 20.04 LTS in my Windows 10 PC (with an NVIDIA GeForce Gt 730 graphics card). It requires certain packages installed (freeglut3-dev, gfortran, gnuplot and Mesa OpenGl libraries). I have been able to install of the packages except the Mesa OpenGl one. When I want to check what version I have, I get the following:
glxinfo | grep "OpenGL version"Error: unable to open displayNot sure what needs to be done in order to first have Mesa OpenGl package installed and working and second to be able to see what version I have.
Note I am completely new to Ubuntu and this packages so my knowledge about installing packages and everything is really limited.
