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

Grub2 is displaying full 1920x1080 resoltuion -- but as soon as I run of
the kernel options, it switches to BIOS resolution (text mode) and runs
like that for a few seconds (non-"quiet" spits out a bunch of
init/kernel messages) -- and only later switches to a full graphics mode
again.
How do I make it stay in high resolution mode all the time??


What I've tried so far:
* checked that grub2 has "set gfxmode=auto" and "set gfxpayload=keep"
* tried booting without initrd entry -- in the past, that used to boot
kernel in current grub resolution and show a number of penguins. Now
it's just text..
* tried booting with and without plymouth ("rhgb" option in kernel line,
and yum-removed plymouth* with regenerating initramfs by "dracut -f")


Some more info:
bumblebee and nvidia driver are installed to run the nvidia card --
everything works great in X
current kernel 4.1.5-100.fc21.x86_64

Not sure who to file a bug against -- grub2? kernel? etc?
