Pergunta:

Como posso criar um arquivo de configuração para que meu kernel Linux ou qualquer outro leia esse arquivo quando estou escrevendo startxpara carregar a tela gráfica?

  1. Como deve ser a aparência do arquivo?
  2. Onde ele deve ser colocado?
  3. O que o arquivo deve conter?

    Isenção de responsabilidade: tenho bastante experiência no servidor X.org X11 no Linux, mas nenhuma experiência pessoal em configurá-lo em hardware ARM.

    Notei que as notas de lançamento do STM32 indicam que o Wayland e seu Weston display composer foram atualizados especificamente para o STM32 - mas não há menção aos drivers de display X.org correspondentes. Receio que isso possa significar algo entre esses casos:

    • Melhor caso: o ARMSOCdriver X.org já suporta seu hardware bem o suficiente para que nenhuma alteração fosse necessária - é só que a autosondagem dos monitores não funciona muito bem, e você pode precisar configurar as resoluções dos monitores e os limites do clock de pixel de uma maneira tradicional. Pela sua pergunta, acho que é isso que você está esperando.
    • Pior cenário: os desenvolvedores do STM32 podem ter colocado todos os seus esforços de driver GUI no Wayland em vez do X.org, e somente o Wayland está atualmente documentado e funcionando. Talvez o stmdriver DRM do kernel tenha recursos suficientes implementados para o Wayland, mas algo que o servidor X11 precisa ainda não foi implementado. Ou talvez o ARMSOCdriver X11 precise de um patch específico do STM32.

    O stmdriver DRM do kernel parece ser específico para a plataforma STM32, pois não consegui encontrar nenhuma documentação sobre ele em nenhum outro lugar.

    Então, se você quer apenas uma sessão GUI e não se importa se é X11 ou Wayland, tente este comando em vez de startx:

    systemctl restart weston-graphical-session

    como diz na documentação do STM32 . Nesse caso, o arquivo de configuração para a exibição GUI baseada em Wayland seria /etc/xdg/weston/weston.ini.

    Mas se você quiser especificamente o X11, você pode pedir ao servidor de exibição X11 para produzir um modelo de arquivo de configuração para você, executando este comando como root:

    Xorg -configure

    Isso deve produzir um /root/xorg.conf.newarquivo, que deve ser um arquivo de modelo mais ou menos completo xorg.conf. Note que você provavelmente não precisará do arquivo de configuração completo, pois o servidor X moderno é geralmente muito bom em autoprobing o hardware.

    So you might pick from the configuration template just the one or two sections the driver seems to be having trouble autoprobing: perhaps just the Monitor and maybe Screen sections. Fill them out with valid data (see man xorg.conf for details) and place just those sections into a /etc/X11/xorg.conf.d/stm32.conf file, for example.

    The really old-school way to configure the X11 server would be to take the whole template, copy it to /etc/X11/xorg.conf and fill out any missing data (e.g. the monitor pixel clock limits and maximum resolutions, as the driver doesn't appear to be able to autoprobe them currently).

    This might be more trouble than it's worth, as you might have to fill out any input device configuration (i.e. configuration information for keyboard and mouse) too.
