Tengo un monitor HDMI conectado a mi computadora portátil Ubuntu y normalmente trabajo con la tapa de mi computadora portátil cerrada.
Por alguna razón, de repente la configuración dejó de funcionar.
Ahora, cuando cierro la tapa, la pantalla del monitor externo se vuelve negra como si no hubiera señal, pero el sistema no se suspende ni hiberna porque cuando abro la tapa todo comienza desde donde lo dejé (sin pantalla de inicio de sesión).

De:Problema al cerrar la tapa:
Para que Ubuntu no haga nada cuando la tapa de la computadora portátil está cerrada: abra el /etc/systemd/logind.confarchivo en un editor de texto como root, por ejemplo
sudo -H gedit /etc/systemd/logind.conf
Agregar una líneaHandleLidSwitch=ignore
Reinicie el demonio systemd con este comando:
sudo service systemd-logind restart
Si eso no funcionó, configure lo siguiente
IgnoreLid=trueen/etc/UPower/UPower.conf
