salve, non so se sono nel forum giusto; in caso indicatemi quello più adatto...
Allora, il mio sistema operativo è Ubuntu (ultima versione), e il mio monitor è un LG FALTRON M2262D collegato alla scheda video tramite cavo vga.
Il mio problema è che spesso il monitor si spegne (come se vada in standby per pochi secondi) e poi si riaccende.
Perchè?
Se può essere utile, ecco l'output di alcuni comandi che ho dato da terminale:
