update-grub-gfxpayload (8) Linux Manual Page
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
