Ciao a tutti, vi chiedo cortesemente se sapete dirmi come mai collegando il mio portatile alla tv tramite porta VGA, vedo non vedo nessun effetto (schermata tv nera e portatile funzionante)?
Io ho Ubuntu 18.04,
digitando lspci, ottengo:

Non riesco a capire se il problema è di driver o altro. Scusatemi ma ho Ubuntu da poco e sto cercando di entrare in questo mondo, ma non ho molte conoscenze.

Grazie anticipatamente

Sul TV ti sei assicurato di aver selezionato l'ingresso corretto?

Posta per favore una schermata delle impostazioni dei display, a TV connessa e accesa, dovrebbe chiamarsi Monitor.

Ciao dadexix86, grazie per la risposta, scusa il ritardo, ma sono stato impegnato con il lavoro e con la mia bimba di 10 giorni e non ho potuto risponderti prima...

Il link dello screenshot che mi hai chiesto è: https://imgur.com/TfR6zXd (non posso allegare immagini). sono sicuro di aver selezionato l'ingresso corretto della tv.

Ho il dubbio di dover attivare la porta VGA perchè utilizzando ARandR, nella sezione output, posso selezionare solo LVDS-1, mentre VGA rimane grigio....
