Estimados,
Tengo una portatil Acer que venia funcionando perfecto, la desenchufe del
HDMI, la volví a enchufar y no volvio a detectar el hdmi. Actualice el
Sistema a ver si con las últimas actualizaciones se corregía. Es muy raro
lo que paso, mientras se mantuvo conectado el hdmi la reinicie muchas veces
y no tuve inconvenientes.
Estoy usando Debian testing como repositorios.
No se como forzar para que detecte el hdmi. Volví a instalar el paquete
xserver-xorg-video-intel (ya estaba instalado) pero no resolví el problema.
Gracias, paso algunos datos de mi sistema:
