Ativar driver de gráficos vulkan para mesa (oibaf)

Question

Estou em um Ubuntu 16.04 64bit usando uma AMD radeon r9 de 390 gpu

Recentemente eu instalei o driver "amd gpu-pro-17.10" e tive o Vulkan funcionando, e pude reproduzir o Dota 2 com melhor desempenho que no Windows.

Mas executando o World of Warcraft 7.3 eu tive um pouco de fps baixos em ataques.

Eu decidi testar o driver gráfico The mesa com suporte a Gallium Nine, que o WineHQ recomenda para o WoW.

Parte importante !!! Eu desinstalei o driver "amd gpu-pro".

Então eu instalei o "oibaf graphics driver", seguindo este tutorial https://wiki.ixit.cz/d3d9_tutorial

Rebooted e agora o Vulkan não está funcionando.

Não consigo encontrar ajuda para ativar o vulkan neste novo driver gráfico.

Veja estes dois arquivos:

/usr/share/vulkan/icd.d/radeon_icd.i686.json
/usr/share/vulkan/icd.d/radeon_icd.x86_64.json

Eles devem ser parecidos com:

/usr/share/vulkan/icd.d/radeon_icd.i686.json

{
    "file_format_version" : "1.0.0",
    "ICD": {
        "library_path": "/usr/lib32/libvulkan_radeon.so",
        "api_version" : "1.0.49"
    }
}

/usr/share/vulkan/icd.d/radeon_icd.x86_64.json

{
    "file_format_version" : "1.0.0",
    "ICD": {
        "library_path": "/usr/lib/libvulkan_radeon.so",
        "api_version" : "1.0.49"
    }
}

Se não, você pode modificá-los para uma correção rápida e, por favor, relatar como um erro de empacotamento se isso resolver o problema.

Eu não possuo uma placa AMD, mas falei com uma alma gentil para descobrir que a biblioteca apropriada deveria ser, já que este é um problema conhecido com alguns pacotes da nvidia.
