[Bug 1462609] Re: Ubuntu 15.04 Blank screen boot up

[Lukasz_S]

Happens intermittently on cold boot, reboot and waking from sleep. From
the observation so far I had two successful boots in a row, didn't have
two black screen boots in a row.

My hardware: Dell Inspiron 5558, Intel HD 5500 / Nvidia 920M, running
Bumblebee with proprietary Nvidia driver (I'll add lspci output later).
