Sono completamente in perdita. In una nuova installazione di Ubuntu 16.04 LTS a 64 bit, lo schermo del mio laptop ha iniziato a diventare nero ogni 15 secondi. Se muovo il mouse o faccio clic, il display ritorna (Non devo accedere). Perché questo accade ogni 15 secondi, il laptop è essenzialmente inutilizzabile. Sembra un comportamento salvaschermo ma potrebbe essere qualsiasi cosa.

Inutile stare se andare su Impostazioni> Impostazioni di sistema ... e modificare Brightness and Lock
, Power
o Screen Display
questo non ha alcun effetto sul problema. Io non so cosa fare. Qualsiasi aiuto sarebbe apprezzato.
