{{outdated|These instructions were written when the generic image did not work. Using the vendor kernel may be desirable under some conditions<sup>[which?]</sup>}}
Using <code>nixos-generate-config</code> will generate the required minimal configuration.


Using <code>nixos-generate-config</code> will not generate the required minimal configuration.
For better GPU Support and some deviceTree quirks add the nixos-hardware channel:
 
<code>nix-channel --add https://github.com/NixOS/nixos-hardware/archive/master.tar.gz nixos-hardware</code>
For better GPU Support, remember to add the nixos-hardware channel:
