* A quick hack to get accelerated OpenGL working: just use the driver

Browse source 
in /usr/lib/libGL.so.1 (which will typically load a driver in
  /usr/X11R6/lib/modules/dri).  This has been tested on a i915
  graphics card; it should work with most open source X.org drivers.
  For NVidia's proprietary drivers (which we cannot build ourselves
  anyway), some more symlinks are necessary; I'll add those later.

  So to get hardware-accelerated Quake 3, do:

  $ nix-env -p /nix/var/nix/profiles/opengl -i xorg-sys-opengl
  $ nix-env -i quake3-demo
  $ quake3

This program will look for a hardware-accelerated implementation of
OpenGL in the "$profileName" profile of your Nix installation. For
instance, to enable NVidia's accelerated driver on non-NixOS systems,
try
instance, to enable the (hopefully) accelerated driver provided by
your (non-NixOS) Linux distribution, try
$ nix-env -p $profile -i nvidia-sys-opengl
$ nix-env -p $profile -i xorg-sys-opengl
Alternatively, you can set the OPENGL_DRIVER environment variable to
point at the package containing the OpenGL implementation.
