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 AUTHOR
