Motivation

You use Nix on any distribution, and any GL application installed fails with this error:

$ program
libGL error: unable to load driver: i965_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: i965
libGL error: unable to load driver: i965_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: i965
libGL error: unable to load driver: swrast_dri.so
libGL error: failed to load driver: swrast

This library contains a wrapper which is able to launch GL application:

nixGLXXX program

Installation / Usage

Clone this git repository:

git clone https://github.com/guibou/nixGL
cd nixGL

Optional (if NVIDIA) Grab your NVIDIA driver version

Using glxinfo from your host system, grab the driver version, here 390.25:

$ glxinfo | grep NVIDIA
...
OpenGL core profile version string: 4.5.0 NVIDIA 390.25
...

Build

For intel:

nix-build -A nixGLIntel

For NVIDIA alone:

nix-build -A nixGLNvidia --argstr nvidiaVersion 390.25

(replace 390.25 with the host driver version gathered earlier.)

For Nvidia with bumblebee:

nix-build -A nixGLNvidiaBumblebee --argstr nvidiaVersion 390.25

(replace 390.25 with the host driver version gathered earlier.)

Install

nix-env -i ./result

(Note, you can iterate many time on this process to install as many driver as needed. Common example are nixGLIntel with nixGLNvidiaBumblebee)

Usage

nixGLXXX program args

For example (on my dual GPU laptop):

$ nixGLIntel glxinfo | grep -i 'OpenGL version string'
OpenGL version string: 3.0 Mesa 17.3.3
$ nixGLNvidiaBumblebee glxinfo | grep -i 'OpenGL version string'
OpenGL version string: 4.6.0 NVIDIA 390.25

Limitations

Does not work now for AMD drivers because I dont' have the hardware.
