Here's a workaround that solved the problem for me:
1) enable framebuffer mode:
echo FRAMEBUFFER=y > sudo tee /etc/initramfs-tools/conf.d/splash sudo update-initramfs -u
2) add this line to /etc/default/grub (The resolution has to be supported by BIOS. To check, execute vbeinfo at grub2 prompt.):
GRUB_GFXPAYLOAD_LINUX=1024x768
3) and finally:
sudo update-grub2
