Mesa drive 19 para Debian Híbrido

Confira nessa matéria as novidades do Mesa drive 19 e como o instalar em seu Debian testing híbrido.


O projeto Mesa começou como uma implementação de código aberto da especificação OpenGL. APIs, incluindo OpenGL ES (versões 1, 2, 3), OpenCL, OpenMAX, VDPAU, API VA, XvMC e Vulkan.

Uma variedade de drivers de dispositivos permite que o Mesa seja usado em diversos ambientes, desde a aceleração de software até hardware para GPUs modernas.

O Mesa se une a vários outros projetos de código aberto: o Direct Rendering Infrastructure e o para fornecer suporte ao OpenGL no Linux, FreeBSD e outros sistemas operacionais.


Identificando o drive

Identificando o drive Mesa instalado em sua maquina, de o comando abaixo no terminal.

glxinfo | grep version

No meu caso já estou com a versão 19.

OBS: A versão do OpenGL é definida por sua placa de vídeo, a versão apresentada é a suportada por ela.


A instalação é até o momento exclusiva para usuários do Debian testing híbrido com experimental, portanto não instale de forma alguma no Debian stable (Stretch).

Se você já usa o Debian testing mas ele ainda não é híbrido e você gostaria de testar a nova versão do Mesa, siga a matéria abaixo referente ao seu sistema para tornar o seu Debian híbrido.

Com o seu sistema híbrido de os comandos abaixo no terminal.

Adicionando arquitetura i386 ( 32 bit ), de o comando abaixo no terminal.

sudo dpkg --add-architecture i386

Instale o Mesa 19.

sudo apt install -t experimental libegl1-mesa libegl1-mesa-dev libgl1-mesa-dri libgl1-mesa-dri:i386 libgl1-mesa-glx libgl1-mesa-glx:i386 libglapi-mesa libglapi-mesa:i386 libgles2-mesa

Notas de versão do Mesa 19.0.0

O Mesa 19.0.0 é uma nova versão de desenvolvimento. As pessoas que estão preocupadas com estabilidade e confiabilidade devem manter uma versão anterior ou esperar pelo Mesa 19.0.1.

O Mesa 19.0.0 implementa a API do OpenGL 4.5, mas a versão relatada por glGetString (GL_VERSION) ou glGetIntegerv (GL_MAJOR_VERSION) / glGetIntegerv (GL_MINOR_VERSION) depende do driver específico que está sendo usado. Alguns drivers não suportam todos os recursos necessários no OpenGL 4.5. O OpenGL 4.5 só está disponível se solicitado na criação do contexto. Os contextos de compatibilidade podem reportar uma versão inferior, dependendo de cada driver.


  • GL_AMD_texture_texture4 on all GL 4.0 drivers.
  • GL_EXT_shader_implicit_conversions on all drivers (ES extension).
