== Testing Mesa updates == | |||
To avoid a lot of rebuilds there's an internal NixOS option to override the Mesa drivers: <code>hardware.opengl.package</code> | |||
It can be used like this: <code>hardware.opengl.package = (import /srv/nixpkgs-mesa { }).pkgs.mesa.drivers;</code> | |||
However, since Mesa 21.0.2 this doesn't necessarily work anymore and something like the following might be required: | |||
<pre> | |||
system.replaceRuntimeDependencies = [ | |||
({ original = pkgs.mesa; replacement = (import /srv/nixpkgs-mesa { }).pkgs.mesa; }) | |||
({ original = pkgs.mesa.drivers; replacement = (import /srv/nixpkgs-mesa { }).pkgs.mesa.drivers; }) | |||
]; | |||
</pre> | |||
