I have been assigned a homework on my C++ class using OpenGL and GLUT. When I try to run the project, it runs very slowly and it freezes after a little bit. Before the program runs I get the following error:

extension "NV-GLX" missing on display

If have tried:

  • Installing the driver from NVIDIA website.
  • Installing the driver by following the instructions in this thread: extension "GLX" missing on display
  • Installing/Uninstalling the drivers several times.

All of this without any success. I am not a Linux expert, and this is my first time dealing with Linux seriously, so if you could please set me in the right direction I would appreciate it.

Thanks.

because you are running Ubuntu under virtual box, you don't need the Ubuntu drivers - you just need the virtualbox virtual display driver. You can get it by installing the VirtualBox "guest additions"
