background image and hidden timeout

[Oliver Seitz]

Hi!

Sorry if this mail arrives twice, I've sent it again when it did not 
appear in the list archives after five hours.


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
