I nailed down that the echo (even of an empty string) has to be before
"terminal_output gfxterm". Once it is after the "terminal_output
gfxterm" instruction, the menu and background do not shows up.
Note: I also tried "GRUB_TIMEOUT_STYLE=menu" in /etc/default/grub
followed by update-grub and it did not help with this issue.
Cheers
