    Re: Grub 2 - 5 Common Tasks

    What you are seeing is the usplash image. The Grub2 splash image is the background behind your menu on the screen.

    I take it you only have one OS on your box.

    You need to go to /etc/default/grub and edit the file. You need to hash the line;
    Code:
    GRUB_HIDDEN_TIMEOUT=0
    so it reads
    Code:
    ## GRUB_HIDDEN_TIMEOUT=0
    Dell 480 XPS 3G ram Quad Core 2.40GHz, Radeon HD 2400 PRO, Audigy1, 3x320G HDD, 320G External, Debian Testing for use, Debian Squeeze for secure use, Debian Sid for FUN

    Thnxs for quick reply. yes only one os. I #'d out that line - updated but no difference - then I tried #ing out the line below to but also no difference.

    grub looks like this now:
    Code:
    GRUB_DEFAULT=0
    # GRUB_HIDDEN_TIMEOUT=0
    # GRUB_HIDDEN_TIMEOUT_QUIET=true
    GRUB_TIMEOUT="0"
    GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
    GRUB_CMDLINE_LINUX=""
    
    # Uncomment to disable graphical terminal (grub-pc only)
    #GRUB_TERMINAL=console
    
    # The resolution used on graphical terminal
    # note that you can use only modes which your graphic card supports via VBE
    # you can see them in real GRUB with the command `vbeinfo'
    GRUB_GFXMODE=640x480
    
    # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
    #GRUB_DISABLE_LINUX_UUID=true
    
    # Uncomment to disable generation of recovery mode menu entrys
    #GRUB_DISABLE_LINUX_RECOVERY="true"
    you can see I'd earlier un#ed the grub_gfxmode line as well. It wouldnt be anything to do with the screen res on the eee (1024 x 600) would it?

    It appears that you a the grub timeout we at 0. I would increase that.

    You have to remember to run;
    Code:
    sudo update-grub
    for any change to take place.

    Re: Grub 2 - 5 Common Tasks

    Excellent thanks. So
    # GRUB_HIDDEN_TIMEOUT=0
    GRUB_TIMEOUT="1"

    brings up the splash image for a couple of secs overlaid by the text but it soon disappears to be replaced by the monochrome ubuntu splash again. Is that supposed to happen? I thought the new splash screen would stay on until I got to gdm?

    Nope. The goal is to replace usplash with upstart but that has not worked yet. So, you get the grub menu, upsplash, xsplash, GDM and then xsplash again on booting.

    Hopefully this is resolved in 10.04.

    Re: Grub 2 - 5 Common Tasks

    I have more than one OS installed but still want to hide the menu unless I press shift. Following your OP does not work for me. Is it possible to hide the menu with more than one OS installed at all?

    EDIT: Nevermind I fixed it. To hide the menu you also have to set GRUB_TIMEOUT=0.

    In /etc/default/grub, set the GRUB_HIDDEN_TIMEOUT to 0 or a positive integer.

    Hiding the menu is a problem for some users (including me on some systems). Here are some of the ways that might work for you. Each one is separate from the others and should start from an unchanged system (i.e. restore the original settings before trying the next).


    1. Add this line to /etc/default/grub
    GRUB_DISABLE_OS_PROBER=true
    run sudo update-grub
    Leaving it set up like this will not allow G2 to find updates on other partitions/OSs. The next post may work without giving up this feature.

    2. Refer to post #17 in this thread:

    3. Refer to this bug report:

    Re: Grub 2 - 5 Common Tasks

    Maybe this is obvious for those more experienced with editing Linux config files than I am (newb), but it might be helpful to add a note that when adding a background image, the image name is case sensitive. That caught me up at first.

    Thanks for the writeup!

    This is true of Linux in general. But if it happened to you it is 100% certain it's happened to others.

    Unhappy Re: Grub 2 - 5 Common Tasks

    I have installed grub2-splashimages and edited /etc/grub.d/05_debian_theme to point to the chosen image, but I got the following error when updating grub:

    Code:
    Generating grub.cfg ...
    /etc/grub.d/05_debian_theme: 3: source: not found
    /etc/grub.d/05_debian_theme: 31: is_path_readable_by_grub: not found
    Found linux image: /boot/vmlinuz-2.6.31-20-generic
    Found initrd image: /boot/initrd.img-2.6.31-20-generic
    Found linux image: /boot/vmlinuz-2.6.31-19-generic
    Found initrd image: /boot/initrd.img-2.6.31-19-generic
    Found memtest86+ image: /boot/memtest86+.bin
    Found Windows 7 (loader) on /dev/sda1
    done
    Ant guess on how to fix this?
    Thx
