NAME
update-grub-gfxpayload — update /boot/grub/gfxblacklist.txt
SYNOPSIS
update-grub-gfxpayload
DESCRIPTION
update-grub-gfxpayload updates /boot/grub/gfxblacklist.txt from source files in
/usr/share/grub-gfxpayload-lists/blacklist/, which disables GRUB's gfxpayload=keep facility with certain
graphics cards. It should normally only need to be called internally by packages.
If you need to disable gfxpayload=keep locally (perhaps because your system starts up with a black or
corrupt screen), then you do not need this program. Instead, add this line to /etc/default/grub:
GRUB_GFXPAYLOAD_LINUX=text
