Same problem. I've edited the appropriate file /etc/grub.d/00_header to "set gfxpayload=1024x768x16". Then ran sudo update-grub to update the grub.cfg file. I then open the grub.cfg file to verify & it is updated. But when I reboot my computer I get the grub2 screen for OS selection, choose Ubuntu, then all I get is a blinking cursor on the upper-left.
I too have a nVidia card. Using the depreciated "vga=791" works.
