Multi-sede com o Kubuntu 17.10 / Artful (systemd, sddm, KDE)

Navegue suas respostas
1

Eu quero configurar vários lugares no meu PC. Eu já adicionei um segundo adaptador VGA para tornar as coisas mais fáceis / possíveis ?.

Temos:

  • Kubuntu Artful 17.10 (KDE)
  • systemd
  • sddm (provavelmente precisamos usar o lightdm, já que o sddm não possui recursos de várias sedes)
  • Intel gfx on-die i5-4570S
  • ATI RV710 / Radeon HD4350 / 4550 muito antigo

Vamos tentar documentar uma solução genérica para versões recentes do Kubuntu / Ubuntu.

Estou convencido de que, se eu começar o X, não tenho nenhuma entrada em seat0 e ruído aleatório em seat-tv .

Criei uma nova pergunta porque as perguntas / respostas existentes são especializadas em hardware ou incompletas para explicar o histórico. Pelo menos eu não consegui resolver o problema usando fontes existentes.

Eu criei uma resposta da comunidade, então sinta-se à vontade para editar a resposta abaixo.

Quando terminar, devo acrescentar como iniciar o Kodi apenas sem o gerenciador de exibição e o gerenciador de janelas na TV do assento.

Antes de começar

  • Backup do seu sistema e / ou etc
  • Instale openssh-server e verifique se você pode fazer login em outro computador, caso o login local não funcione
  • desativar o início automático do gerenciador de exibição: sudo systemctl set-default multi-user.target
  • pense em um bom nome para seus lugares. Convenções diz que tem que começar com seat- . Eu escolho seat-tv .

Configurar regras do udev

  • leia sobre as regras do udev aqui link link

  • encontre seu hardware usando um desses

  • adicione regras por ...

    • usando loginctl plus acima dos pathes para criar as regras do udev, mas não recomendo. Os IDs dos ônibus permanecem os mesmos? 

      # gfx
sudo loginctl attach seat-tv /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/drm/card0

    • Isso adiciona arquivos de regras como os seguintes. A regra define ID_SEAT como seat-tv se ID_FOR_SEAT corresponder ao dado. 

      $ cat /etc/udev/rules.d/72-seat-graphics-pci-0000_01_00_0.rules'
TAG=="seat", ENV{ID_FOR_SEAT}=="graphics-pci-0000_01_00_0", ENV{ID_SEAT}="seat-tv"

    • ou criando as regras do udev manualmente. Eu prefiro VendorID / ProductID para identificação. Nomes de arquivo devem começar com 72 porque outras coisas relacionadas a assentos em /lib/udev/rules.d são 71 ou 73. 

      $ cat 72-seat0.rules

  • você deve agora (após a reinicialização do gerenciador de exibição?) perceber o seguinte

    • as entradas atribuídas a outros lugares não devem funcionar mais no assento0
    • as telas atribuídas a outros lugares devem desaparecer das configurações do sistema / exibir
    • mesmo para o dispositivo de áudio

Configuração do Xorg

  • crie um diretório como /etc/X11/xorg.conf.multiseat para que ele não altere sua configuração padrão.
  • buscar a configuração atual do xorg com sudo Xorg :2 -configure

  • crie o arquivo /etc/X11/xorg.conf.multiseat/90-seat-tv.conf 

    Section "Device"
        # get this from Xorg -configure
        Identifier  "Card0"
        Driver      "amdgpu"
        BusID       "PCI:1:0:0"

        MatchSeat      "seat-tv"

EndSection

  • Eu não sei sobre as entradas comentadas.

  • Preciso de um arquivo semelhante para seat0 ou os padrões estão ok?
  • TODO: layout do servidor

Teste

  • logout do gui e desligue o gerenciador de janelas usando sudo service sddm stop
  • inicie o X em todos os seus lugares - um após o outro - e veja o que acontece. startx -- -layout seat0 -config xorg.conf.multiseat , consulte link

Desfazer

  • temporariamente
    • ative seu gerenciador de janelas novamente sudo systemctl set-default graphical.target
  • permanentemente
    • exclua seus arquivos udev /etc/udev/rules.d/72-*
    • elimine a sua pasta /etc/X11/xorg.conf.multseat

E agora?

  • O que estou perdendo?
  • Como funciona o layout do servidor?
  • O teclado da Mele de alguma forma não está conectado à TV do assento?
