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
