Set GRUB console-mode resolution

Question

I can't figure out how to set the resolution for text-mode GRUB - that is, with the GRUB_TERMINAL=console option set in /etc/default/grub. When I set a resolution using GRUB_GFXMODE or GRUB_GFXPAYLOAD, I get a "no video mode set" error on boot, and when I try to set resolution using GRUB_CMDLINE_LINUX_DEFAULT="vga=xxx", I get a message saying that vga=xxx is deprecated. I have a 1080p screen, and I can get the framebuffer terminal inside Linux working just fine, but I can't figure out how to set any resolution at all for non-graphical GRUB. I am using the proprietary nVidia drivers, which is the entire reason I am running GRUB in text mode to begin with.

My current GRUB settings:

GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=0
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT=""
GRUB_CMDLINE_LINUX=""
GRUB_TERMINAL=console
GRUB_GFXMODE=1920x1080x32
GRUB_GFXPAYLOAD=640x480x32
GRUB_GFXPAYLOAD_LINUX=1920x1080x32
GRUB_INIT_TUNE="480 440 1"

Solution

Try this:

1. Open terminal, sudo -H gedit /etc/default/grub
2. Change the resolution you need in GRUB_GFXMODE=
3. Add this line right below it >> GRUB_GFXPAYLOAD_LINUX=keep
4. Save & Exit
5. Type in terminal: sudo update-grub
6. Then finally: sudo grub-mkconfig -o /boot/grub/grub.cfg
7. Reboot

What's the purpose of the last command? Isn't update-grub enough? If not, why not?

The last command consolidate the new resolution to be set by default every time you boot, there is many issues with hybrid graphic cards that obstructs any change on grub ( For instance, Nvidia graphic cards sets grub on the highest possible resolution your hardware can offer)

This didn't work - I still get the "no video mode" error, but now all my ttys are at a very low resolution (640x480, I assume). This happens regardless of whether the GRUB_GFXPAYLOAD line is present or not.
