For ordinary operation, it looks like the initial graphic resoution is
controlled by the
        set gfxpayload=[value]
lines in /boot/grub2/grub.cfg.  The default is "keep", which seems to
leave the screen in whatever configuration the VGA card was at initial
boot.  To specify a particular size, you can replace "keep" with, say,
"1024x768".  More details are at
