Eu tenho o Ubuntu 14.04 com login automático para minha sessão e gráficos da Intel. Meu objetivo é ser capaz de iniciar o Ubuntu sem nenhuma tela conectada. Eu também quero girar para a esquerda.
Na verdade, se eu iniciar meu monitor DP ou HDMI após a inicialização, não consigo trabalhar. O servidor X não pode ser iniciado. No passado eu tinha placa gráfica Nvidia e era possível com o parâmetro allowemptyinitialconfiguration. Para meu cartão de inteligência, tentei com uma interface fictícia, mas sempre exibe uma tela preta quando meu monitor está ligado.
Além disso, se eu ligar e iniciar o meu monitor antes de inicializar o ubuntu, eu tenho a tela funcionando, mas a rotação não se mantém após o desligamento e no monitor. Eu tentei usar o monitors.xml em ~ / .conf /, mas essa solução só funciona para um fornecedor e um modelo de exibição. Eu gostaria de fazer isso funcionar para qualquer exibição.
Outra solução que encontrei é usar as regras do udev para detectar alterações e executar um script que usará o xrandr para configurar a rotação. Esta solução parece funcionar, mas às vezes não gira.
Esta é a saída de xrandr --verbose & ls /sys/class/drm/*/edid | xargs -i{} sh -c "echo {}; parse-edid < {}"

Hmm, you have data blocks, but not video ones... weird

Se alguém já teve esse problema ou se você tem alguma solução, por favor ajude.
Finalmente, consegui que funcionasse. Eu não fiz nenhuma alteração na minha configuração do Ubuntu. Acabei de alterar os parâmetros no meu menu de TV.
Para fazê-lo funcionar, mudo o sinal HDMI de RAW para EXPAND e DisplayPort 1.1a para 1.2.
Agora posso iniciar o Ubuntu sem nenhum monitor conectado e a rotação da esquerda está ok depois de ligá-lo e desligá-lo.
Alguém pode me explicar esse comportamento?
