Think of OpenGL as the free version of DirectX. Setting the OpenGL library determines what kernel module does the heavy lifting in rendering. By heavy Lifting, I mean 3d Acceleration, optimization etc

It sets a bunch of symlinks and copies files to the correct place. This includes header files for compiling as well as libraries in /usr/lib.

The code is in /usr/share/eselect/modules/opengl.eselect

Things it does not affect:
  • Anything to do with the kernel or kernel modules (the above post is completely wrong)
  • Anything involving /etc/X11/ files
