background image and hidden timeout

[Oliver Seitz]

Hi!

I'd like to use grub2 to usually boot one system. Boot selection menu is 
normally not needed, and should be hidden. However, it would be nice if 
grub could display a background image.

I have (besides the standard ones) these statements in /etc/defaults/grub:

GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=10
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""
GRUB_BACKGROUND="/path/to/filename.png"
GRUB_GFXMODE=1280x1024

This works:

gfxmode is correctly set
hidden timeout is passing
the background image is displayed
timeout is passing
default is booting

This doesn't work:

The menu is displayed after the hidden timeout, no matter if asked for 
or not. This can be a problem with detecting shift key, haven't looked 
into this one too much yet. What is more annoying:

The background image is not displayed until a key is pressed, or the 
menu is shown.

I'd like it best, if even the "GRUB loading./Welcome to GRUB" message 
was not displayed, and as soon as possible the background image would be 
shown without the menu.

Is it a bug, a missing feature or misconfiguration? Some docs like
https://help.ubuntu.com/community/Grub2#Hidden explain the hidden time 
as "No menu entries are displayed. The splash screen, if configured, 
will be displayed. "


Thanks for any help,
Kiste
