sul mio notebook Lenovo Z50-70 ho una CPU Intel(R) Core(TM) i7-4510U con GPU Intel HD Graphics 4400 integrata e GPU Nvidia GeForce 840M. Ho installato sia i driver proprietari di Nvidia, sia bumblebee. Funziona tutto.
All'avvio del notebook il display viene gestito dalla GPU Intel.
Da qualche parte mi ricordo di aver letto che è possibile impostare il sistema in modo che all'avvio il display venga gestito dalla GPU Nvidia, senza disinstallare bumblebee, ma semplicemente ritoccando qualche profilo dei driver Nvidia. Chi mi da qualche dritta in merito? Se avvio il pannello di controllo dei drivers Nvidia, questo mi appare vuoto (vedi screenshot)
