I've fighted a lot with prop nvidia driver and bumblebee, but finally I
given up :) It was too painful, so I'm using nouveu now and the following
grub config works perfectly. Please note, optimus with nouveau is better
and better every day, so maybe you should give a chance
GRUB_GFXPAYLOAD_LINUX="keep"
GRUB_VIDEO_BACKEND="vbe"
GRUB_TERMINAL_OUTPUT="gfxterm"
GRUB_FONT_PATH="/boot/grub2/fonts/unicode.pf2"
GRUB_GFXMODE="1600x900x32"
You may have to play with the blacklisted modules as well due to the
bumblebee/proprietary config
