Tenho um problema com o Xubuntu Bionic (18.04.3) rodando em um Dell Precision 7530 com um dispositivo de vídeo AMD Radeon Pro WX 4150. Instalei recentemente o driver AMD GPU Pro deeste local, especificamente o arquivo amdgpu-pro-19.30-934563-ubuntu-18.04.tar.xz.
O que está funcionando
- A tela de login de criptografia funciona
- X funciona bem na tela do laptop
- Monitores conectados ao dock (usando o dock WD19DC)
O que NÃO está funcionando
- Saída HDMI no laptop
- Saída Mini-DP no laptop
- OpenGL
- Muitos aplicativos Qt (provavelmente porque o OpenGL está quebrado)
Especificamente, xrandrrelata que conhece as conexões HDMI e DisplayPort no laptop, mas nada é reconhecido quando conectado a essas portas.
Além disso, nada parece funcionar na estrutura OpenGL. Saída de glxinfo:
name of display: :0.0
Error: couldn't find RGB GLX visual or fbconfig
Saída de glxgears:
Error: couldn't get an RGB, Double-buffered visual

Possíveis explicações que explorei, mas ainda pode ser isso
- Tenho arquivos ou pacotes de drivers gráficos concorrentes
- Eu tenho um arquivo de configuração definido incorretamente, em algum lugar
- Outra biblioteca instalada/opcional está afetando a funcionalidade do
amdgpu - Algo mais
eu não instaleia versão Enterprise dos driversporque eles suportam apenas o Ubuntu 18.04.2 e dkmsnão serão compilados com o kernel Linux 5 (mesmo o driver lançado na semana passada).
Eu tentei duas configurações de nível de firmware: sem bypass gráfico integrado. Se o bypass estiver desativado (modo normal), a GPU Intel e a GPU AMD poderão funcionar. Se o desvio de gráficos discretos estiver habilitado, a GPU Intel será ignorada e somente a GPU AMD será habilitada. Embora eu tenha um conjunto diferente de problemas relacionados à comutação, os problemas nesta página afetam ambas as configurações.
Tudo funciona bem no Windows 10, então não acho que seja um problema de hardware.

Depois de muitos experimentos (e instalações completamente novas do Ubuntu e do Xubuntu), encontrei uma solução alternativa: desabilitar totalmente os gráficos alternáveis. Nas configurações do firmware do Precision 7530, posso desligar os gráficos comutáveis e usar apenas a placa discreta. Quando faço isso, as falhas relacionadas ao OpenGL desaparecem, assim como o travamento dos aplicativos Qt.
O modo Direct Discrete (habilitando o chip Intel, mas ignorando-o) era insuficiente. Tive que desligar totalmente a comutação e, nesse ponto, o dispositivo Intel VGA não aparece mais no Linux.
Esta não é exatamente uma solução, mas é uma solução alternativa e é melhor que a alternativa.
Editar: O uso de energia é muito pior nesta configuração. Recebo cerca de metade da duração da bateria. Ainda seria ótimo que isso funcionasse corretamente com o chip Intel ainda habilitado.
