Segunda pantalla no detectada en Ubuntu 18.04

Me estoy conectando con un cable HDMI. Estaba trabajando, pero por alguna razón dejó de trabajar, aquí es lo que hice hasta ahora?

  • Reinicie el equipo y vuelva a conectar;
  • Vaya a configuraciones y compruebe si la pantalla indica arriba, no lo hay;
  • Reinicie el monitor.
  • Probaste con otro monitor con otro cable, el mismo comportamiento sucede.
  • Probé el otro sistema operativo que tengo en el mismo bloc de notas, el mismo comportamiento sucede.
  • Comprueba la misma mesa y monitor con otro notebook, funcionó.

Mis configuraciones:

  • Ubuntu 18.04.3 LTS
  • Gráficos Gráficos Intel® HD 620 (Kaby Lago GT2)

Probablemente tenga un problema con PCIe Lower State. necesita deshabilitar esta función en GRUB.

 GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=noaer"
 

guardó su /etc/default/grub y sudo update-grub , finalmente reinicie su sistema.

Espero que esto ayude.
