BLFS Xorg: Erro de servidor fatal Nenhuma tela encontrada

Question

Estou tentando construir o ambiente do sistema Xorg X Window, conforme descrito em Além do Linux a partir do zero versão 8.0. Meu sistema BLFS reside em uma máquina virtual usando o VirtualBox versão 5.0.10 r104061.

Eu segui as etapas descritas no Capítulo 24. X Window System Environment. No entanto, quando terminei a instalação e tentei o startx, obtive a saída abaixo: -

Eu tentei reconstruir o kernel com

Device Drivers  --->
  Graphics support  --->
   <*> Direct Rendering Manager (XFree86 ... support) --->  [CONFIG_DRM]
   <*> DRM driver for VMware Virtual GPU                    [CONFIG_DRM_VMWGFX]
      [*]   Enable framebuffer console under vmwgfx by default [CONFIG_DRM_VMWGFX_FBCON]

e

Device Drivers  --->
  Graphics support  --->
   <> Direct Rendering Manager (XFree86 ... support) --->  [CONFIG_DRM]

e em ambos os casos recebeu a mesma mensagem de erro. Esta é a saída do lspci para o adaptador gráfico

00:02.0 VGA compatible controller: InnoTek Systemberatung GmbH VirtualBox Graphics Adapter

Alguma ideia de por que as telas não estão carregando?

    

Answer 1

A resposta que eu postei aqui pode ajudar: Configurando o servidor vnc e sem exibição física: Ubuntu 16.04 LTS

Ele configura uma tela virtual para a pilha X para enviar a saída, permitindo concluir a inicialização do ambiente da GUI.
