In Nix mesa is patched to search drivers in /run/opengl-driver directory.

Install mesa-noglu:

$ nix-env -i mesa-noglu

and create symlink

$ sudo ln -s /nix/store/*-mesa-noglu-*-drivers /run/opengl-driver

  • swrast is not under any nix store? Commented Aug 16, 2017 at 6:04
  • @MadRunner: This solution saved me dearly on a related error. Are you aware of a more elegant Nixish solution ? Commented Sep 14, 2017 at 15:40
  • @George using NixOS, I presume. They will likely to have some script or another mechanism to handle different drivers. Commented Sep 15, 2017 at 4:22
