Instalação

Para instalar você pode utilizar o Linux Libre, um kernel 100% Livre, mas tenha em mente que alguns hardwares podem não funcionar com esse Kernel.

Para Debian, Ubuntu e derivados.

 

Para adicionar o repositório do linux libre de os comandos abaixo no terminal.


Log como root.

sudo -i

Instale o apt-transport-https

apt install apt-transport-https

Adicione o espelho do repositório.

echo "deb http://linux-libre.fsfla.org/pub/linux-libre/freesh freesh main" > /etc/apt/sources.list.d/linux-libre.list

Adicione a chave.

wget -O - https://jxself.org/gpg.asc | sudo apt-key add - 

Atualize o apt.

apt update

Para instalar a ultima versão disponível de o comando abaixo.

apt install linux-libre linux-libre-headers

Reinicie o computador para carregar o novo kernel libre.

Eu não troco o Kernel Libre por nenhum outro, ao menos para a minha maquina ele é o que tem o melhor desempenho.
