Meu sistema falhou ao exibir nada depois de acordar do modo de espera. A reinicialização mostrou o bootloader GRUB usual, mas o display não mostra sinal.
Meu sistema:
O lançamento com o failsafe x fornece Display Port, mas o problema persiste em qualquer inicialização normal.
Eu consigo saída do HDMI apenas não da porta de exibição ao inicializar normalmente.
Eu tentei dpkg-reconfigure xserver-xorg & amp; apt install --reinstall xserver-xorg-video-intel sem sucesso.

Eu tenho tido problemas com a suspensão mais antes, mas esta é a primeira vez que a reinicialização falhou em mim: c
Alguma idéia?
