Grub2 Splash image bug or error ?

[apamix]

Hello i have a fresh install kubuntu 10.04 LTS with grub2 and i can't get the splash screen working :S

This is my Grub Version

update-grub -v
/usr/sbin/grub-mkconfig (GNU GRUB 1.98-1ubuntu6)

this is little part of my /etc/grub.d/05_debian_theme

!/bin/bash -e

source /usr/lib/grub/grub-mkconfig_lib

# this allows desktop-base to override our settings
f=/usr/share/desktop-base/grub_background.sh
if test -e ${f} ; then
 source ${f}
else
  WALLPAPER="/boot/grub/77942-wolf.tga"
 COLOR_NORMAL="black/black"
 COLOR_HIGHLIGHT="magenta/black"
fi

set_mono_theme()
{
 cat << EOF
set menu_color_normal=white/black
set menu_color_highlight=black/light-gray
EOF
}

# check for usable backgrounds
[b]use_bg=true[/b]
if [ "$GRUB_TERMINAL_OUTPUT" = "gfxterm" ] ; then
for i in /boot/grub/`basename ${WALLPAPER}` ${WALLPAPER} ; do

And this is the output of the grub update

sudo grub-mkconfig --output=/boot/grub/grub.cfg
Generating grub.cfg ...

done

This is the /etc/default/grub

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.

# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"

And then i reboot my laptop i don't seen the boot splash ? Somebody have a idea why ?

Re: Grub2 Splash image bug or error ?

I don't think your 'little part' of your /etc/grub.d/05_debian_theme is written correctly. It isn't like mine. For your comparison, this is my entire /etc/grub.d/05_debian_theme file. Use it as a guide only.

#!/bin/bash -e

source /usr/lib/grub/grub-mkconfig_lib

set_mono_theme()
{
cat << EOF
set menu_color_normal=white/black
set menu_color_highlight=black/white
EOF
}

# check for usable backgrounds
use_bg=false
if [ "$GRUB_TERMINAL_OUTPUT" = "gfxterm" ] ; then
# for i in {/boot/grub,/usr/share/images/desktop-base}/moreblue-orbit-grub.{png,tga} ; do
for i in {/boot/grub,/usr/share/images/desktop-base,/usr/share/images/grub}/Dragon_wings_1280x800.{png,tga} ; do
if is_path_readable_by_grub $i ; then
bg=$i
case ${bg} in
*.png) reader=png ;;
*.tga) reader=tga ;;
*.jpg|*.jpeg) reader=jpeg ;;
esac
if test -e /boot/grub/${reader}.mod ; then
echo "Found Debian background: `basename ${bg}`" >&2
use_bg=true
break
fi
fi
done
fi

# set the background if possible
if ${use_bg} ; then
prepare_grub_to_access_device `${grub_probe} --target=device ${bg}`
cat << EOF
insmod ${reader}
if background_image `make_system_path_relative_to_its_root ${bg}` ; then
# set color_normal=black/black
set color_normal=yellow/black
set color_highlight=magenta/black
else
EOF
fi

# otherwise, set a monochromatic theme for Ubuntu
if ${use_bg} ; then
set_mono_theme | sed -e "s/^/ /g"
echo "fi"
else
set_mono_theme
fi

Re: Grub2 Splash image bug or error ?

I concur.

This is the relevant part of my lucid debian_theme:

#!/bin/bash -e

source /usr/lib/grub/grub-mkconfig_lib

# this allows desktop-base to override our settings
f=/usr/share/desktop-base/grub_background.sh
if test -e ${f} ; then
source ${f}
else
WALLPAPER="/usr/share/images/desktop-base/background.tga"
COLOR_NORMAL="white/black"
COLOR_HIGHLIGHT="magenta/black"
fi

set_mono_theme()
{
cat << EOF
set menu_color_normal=white/black
set menu_color_highlight=black/light-gray
EOF
}

# check for usable backgrounds
use_bg=false
if [ "$GRUB_TERMINAL_OUTPUT" = "gfxterm" ] ; then
for i in /boot/grub/`basename ${WALLPAPER}` ${WALLPAPER} ; do
if is_path_readable_by_grub $i ; then
bg=$i
case ${bg} in
*.png) reader=png ;;
*.tga) reader=tga ;;
*.jpg|*.jpeg) reader=jpeg ;;
esac
if test -e /boot/grub/${reader}.mod ; then
echo "Found background image: `basename ${bg}`" >&2
use_bg=true
break
fi
fi
done

Re: Grub2 Splash image bug or error ?

The OP's 05_debian_theme file looks exactly like mine in two installs.

Showhog - I think yours is different possibly because you did an upgrade, rather than new install? Yours looks like the theme file from the 9.10 version of grub-pc. To verify, I launched my vbox Karmic and Lucid fresh installs side-by-side to compare.

apamix: I think the issue might be the absence of something in your other files. Look in your /boot/grub/grub.cfg and verify you have this in the header section:

if loadfont /grub/themes/fonts/9x18.pf2 ; then
set gfxmode=640x480
insmod gfxterm
insmod vbe
if terminal_output gfxterm ; then true ; else
# For backward compatibility with versions of terminal.mod that don't
# understand terminal_output
terminal gfxterm
fi
fi

If you do, two things to check/try:

1. Verify your image file is 640x480. I'm using a png file and if I had it the wrong size it would still display, just shrunk or expanded depending, but I don't know if grub-pc handles tga files differently.

2. Try adding set gfxpayload=640x480 below set gfxmode=640x480 in grub.cfg. I realize this edit will be wiped if you run update-grub, but I will tell you how to make it permanent if it works.

Let us know how it turns out. IMO, the graphical part of grub-pc is still a little "buggy". Installs are behaving differently with the exact same settings in some cases.

No. My 10.04 was a 'fresh' installation, both root and /home partitions. My 05_debian_theme is 'modified' just a bit. I have the original (I make copies of system files before I edit them). I'll post it tonight when I get home.

Re: Grub2 Splash image bug or error ?

Interesting that your theme file matches mine from Karmic but my Lucid one match's the OP's.

I'm sure we're both fully updated...odd :P

[Snowhog]

Re: Grub2 Splash image bug or error ?

Rats! I have to correct myself. Yes, my 10.04 was a fresh install. But, It isn't my controlling OS - Karmic is, and that was a Grub Legacy upgraded to Grub 2.

So the 05_debian_theme I posted is from my 10.04, which is what is used when I opt to boot into Lucid as apposed to Karmic. :P

Re: Grub2 Splash image bug or error ?

There ya go... I can stop scratching my head now.

BTW, the Lucid version of grub fixes a few bugs... Time to dump the old grub-y ways and move into the new world, old man!!! lol...

Here, let me help :

grub-install hd0

[Snowhog]

Re: Grub2 Splash image bug or error ?

As I prefer, and do, boot into Lucid 10.04, I should make it the controlling OS. I always install Grub to the root partition. My MBR is empty as far as I know.

So, if I'm booted into Lucid 10.04, running grub-install hd0 will take the controlling Grub 2 and put the boot-strap into the MBR? On a reboot, I'll boot into Lucid's 10.04 Grub menu first?

[oshunluvr]

Re: Grub2 Splash image bug or error ?

I did it by booting up Lucid (from my karmic installed grub-pc), running grub-install /dev/sda (I think you can use device names or grub names), then update-grub. That's all it took. I still boot to my karmic install occasionally, but I'm now using the newer Lucid grub-pc.

A nice change from the old grub...

Re: Grub2 Splash image bug or error ?

And using the same version of Grub on ones installed OS's makes things easier to manage - only have to learn/remember one set of rules.

Re: Grub2 Splash image bug or error ?

There is my /etc/grub/grub.cfg

### BEGIN /etc/grub.d/05_debian_theme ###
insmod ext2
set root='(hd0,1)'
search --no-floppy --fs-uuid --set 54bd0220-ec0d-4ab6-b642-25f1c7d2275b
insmod tga
if background_image /boot/grub/77942-wolf.tga ; then
 set color_normal=black/black
 set color_highlight=magenta/black
else
 set menu_color_normal=white/black
 set menu_color_highlight=black/light-gray
fi
### END /etc/grub.d/05_debian_theme ###

oshunluvr : yes my 77942-wolf.tga is 640x480 its really strange ... and

**@**:~$ sudo ls -la /boot/grub/*.tga
-rw-r--r-- 1 root root 307260 2010-05-12 11:19 /boot/grub/77942-wolf.tga

Now i will try to chmod 777 /boot/grub/77942-wolf.tga and i will replay what's happen
-=> And this not work

Re: Grub2 Splash image bug or error ?

The only thing I can think of is this:

Your wallpaper is in /boot/grub/, correct

Your /boot directory is on /dev/sda1 and /grub is a subdirectory of /boot (not on another partition), correct?

If those statements are both true AND /boot is a separate partition, your /boot/grub/grub.cfg should look like

insmod ext2
set root='(hd0,1)'
search --no-floppy --fs-uuid --set 54bd0220-ec0d-4ab6-b642-25f1c7d2275b
insmod tga
if background_image /grub/77942-wolf.tga ; then
set color_normal=black/black

not

insmod ext2

search --no-floppy --fs-uuid --set 54bd0220-ec0d-4ab6-b642-25f1c7d2275b
insmod tga
if background_image /boot/grub/77942-wolf.tga ; then
set color_normal=black/black

The only other thing I notice is my grub.cfg does not have quotes around (hd0,1). I'm still thinking

Snowhog: Ever try a dedicated grub partition? If you're a flagrant multi-booter like me it prevents accidentally removing your boot files!

Re: Grub2 Splash image bug or error ?

Interesting No i have dual booting i my laptop, but everything looks good
/dev/sda1 on / type ext3 (rw,errors=remount-ro) , so yes /boot is on /dev/sda1
