GRUB_GFXPAYLOAD_LINUX doesn't work

[compdoc]

> I modified "/etc/default/grub" file to fix the resolution of the GRUB
splash screen and Ubuntu adding the following lines:
>GRUB_GFXMODE=1280x720
>GRUB_GFXPAYLOAD_LINUX=keep


I often have to use the option 'GRUB_GFXMODE' to show progress while
booting, but once it's booted I don't think this option has an effect. (for
the desktop)

Also, I don't think it's necessary to use the ' GRUB_GFXPAYLOAD_LINUX'
option. At least, not for me..

And be sure to update grub after the change.
