    11.04 I don't have an xsplash folder, do I create one?

    I would like to either change the boot splash screen to a premade one, or create one. Anyway, looking it up I found a few places which said I need to put the images into the folder /usr/share/images/xsplash. That folder doesn't exist, and I doubt that by creating one, it will suddenly show in the boot splash screen. Any suggestions?

    Your instructions seem a bit dated. Xplash was replaced by Plymouth since Ubuntu 10.04. You didn't say, but I'm assumig since you can't find an Usplash directory, that you are running newer.

    The deault directory for the themes scripts since then has been /lib/plymouth/themes.

    The themes are usually branched off under that in subdirectories where there is a copy of the theme script and all the images for the theme. The default-plymouth script as installed points to ../ubuntu-logo.

    I think with the old directions you have, looking at the files in your /lib/plymouth/themes/ubuntu-logo, you could probably figure it out...

    But if you need help, I could wite an updated tutorial on creating your own. Of course, if you look for "plymouth theme packages" just for something different, there are a lot already out there that you would only just install and it would do everything for you...

The plymouth theme includes the default logo (ubuntu-logo and the five white/red dots), and the logon screen... also affected is the background color and any text...editing the theme profile file, you can change pointers to where images are located and to the theme script file to use....and in that theme script file you can either change everything or mess everything up.

    For example the default ubuntu-logo.script is going to look to most as an overwhelmimg managery...

    # Example:
    #
    #   Thanks to the current implementation, some scripts can call "plymouth --update=fsck:sda1:40"
    #   and this program will know that 1) we're performing and fsck check, 2) we're checking sda1,
    #   3) the program should set the label progress to 40%

    But if you copy the whole subdirectory /lib/plymouth/themes/ubuntu-logo/ to /lib/plymouth/themes/my_custom/ to make a duplicate that you can customise. > Copy in your image file > rename ubuntu-logo.script to my-theme.script > open that file > search for the string
    Code:
    logo_filename = "ubuntu_logo.png";
    And change it to the name of your image. % lines above that isthe filename for a 16bit version of your splash image. Change that filename to your 16bit picture file. .. save and exit. > rename the ubutu-logo.plymouth file to my-theme.plymouth > Open that file and set the pointers of the image directory to this new /lib/plymouth/themes/my-theme/ directory. Set the script pointer to the /lib/plymouth/themes/my_custom/my-theme.script file. > Save and exit.

    Then drop back down to the theme subdirectory > copy the /lib/plymouth/themes/my_cutom/my-theme.plymouth file over/replacing the default-plymouth file... Then update the boot image to include your changes.
    Code:
    sudo update-initramfs -u
    Thats the basic instructions for how I do it. There are some other tools that save some work on picking colors, placing objects on the 2 screen panels and switching between different themes... But if I want to add my "own image"... (Usually someone's company logo, a satirical distro logo or a personal pic)

    EDIT-- There is a package that automates all that in a GUI based tool called "Plymouth Manager." I haven't used it... It's not in the Ubuntu repo's. It is a project at launchpad and is available here:

    Re: 11.04 I don't have an xsplash folder, do I create one?

    Thank you MAFoElffen for the launchpad link, and for clarifying that xsplash is outdated. And thank you Hanunka-Matata for the link, it looks like it will be helpful.
