I want to customize grub's background image, but I don't want to show the grub menu, so I change /etc/default/grub as following:
GRUB_DEFAULT=0 GRUB_TIMEOUT=0 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX="" GRUB_BACKGROUND=/usr/share/images/grub/Glasses_800_edit.tga
It didn't show the image but black color. It only works when I changed GRUB_TIMEOUT > 0 and at the same time shows the grub menu.
Any solutions? THX!!
