After fresh installation of Ubuntu 16.04 I saw boot screen (Ubuntu logo with dots under). Next I installed binary (proprietary) nvidia drivers 340.96 from official packages. After this step I do not see boot screen.
Interestingly, boot screen I do not see, but shutdown screen I see.
I tried add "nomodeset" parameter to Grub (according to some advice), but without success.
Can you help me? It is cosmetic bug..., but I want to see it.
