Vitaly's questions

I am trying to edit my splash screen but its really annoying to restart the computer everytime just to find out it doesn't even work. i read on an article that I can do a virtual machine via ssh but I have no idea how to do that. I installed ubuntu in VirtualBox yesterday now installing sudo apt-get install openssh-server openssh-client on it. Now I am supposed to access the machine as root and test splash on tty1, and I have no idea how to do that. I tried searching around but there isn't a lot of information regarding Plymouth testing on the web.

Any help appreciated, thanks.

I was wondering if it is at all possible to find out when the computer was switched on, what files where accessed what folders were opened, what programs run and when the computer was resumed and put back to sleep (just like in the movies).

I know this isn't that important but it would be cool to know.

I would like to know how to create a splash for Ubuntu Maverick with boot messages being displayed when I boot as well as a progress bar and a spinning logo.

Or, if possible, how to edit a splash which already has a spinning logo and a progress bar, and add boot messages to it.

This is the theme I would like to edit:

• Ubuntu 10.04 and 10.10 Plymouth Splash

and I would like something like this:

or this, which is the exact splash I want to create:

i was able to find this website it has a lot of usefull information but am havin a hard time understanding some of it. havent done any scripting before!

Create your own splash screen with scrolling boot messages

Plymouth Scripting

and this is another website wich can help with scripting

this is the script for the progress bar in the splash:

    #----------------------------------------- Progress Bar --------------------------------

    progress_box.image = Image("progress_box.png");
    progress_box.sprite = Sprite(progress_box.image);

    progress_box.x = Window.GetX() + Window.GetWidth() / 2 - progress_box.image.GetWidth() / 2;
    progress_box.y = Window.GetY() + Window.GetHeight() * 0.65 - progress_box.image.GetHeight() / 2;
    progress_box.sprite.SetPosition(progress_box.x, progress_box.y, 0);

    progress_bar.original_image = Image("progress_bar.png");
    progress_bar.sprite = Sprite();

    progress_bar.x = Window.GetX() + Window.GetWidth()  / 2 -        progress_bar.original_image.GetWidth() / 2;
    progress_bar.y = Window.GetY() + Window.GetHeight() * 0.65  - progress_box.image.GetHeight() / 2 + (progress_box.image.GetHeight() - progress_bar.original_image.GetHeight()) / 2;
    progress_bar.sprite.SetPosition(progress_bar.x, progress_bar.y, 1);

    fun progress_callback (duration, progress)
      {
        if (progress_bar.image.GetWidth () != Math.Int (progress_bar.original_image.GetWidth () * progress))
          {
# add the * 3 to multiply the speed of the progress bar by 3
            progress_bar.image = progress_bar.original_image.Scale(progress_bar.original_image.GetWidth(progress_bar.original_image) * progress * 3, progress_bar.original_image.GetHeight());
            progress_bar.sprite.SetImage (progress_bar.image);
          }
      }

    Plymouth.SetBootProgressFunction(progress_callback);

OK so I did a lot more searching and I was able to learn a bit more about Plymouth.

these are the sites that I found useful. Plymouth theming guide There are four parts to that article you have to read through them to get the gist of what we are doing. (I was comparing their script with the script for my splash to understand what is what, I recommend doing that if anyone is to follow in my footsteps.) Plymouth scripting Ok this link has 2 pages had to go through them to understand what to do. Turns out they were after the same thing I was, which is to direct boot messages to the Plymouth splash where i already have a spinning logo, background, progress bar.

So i had to edit my /lib/lsb/init-functions file and make it so that it would send the boot error/success,etc messages to Plymouth by adding this paragraph

# SEND MESSAGES TO PLYMOUTH
if [ -x /bin/plymouth ] && pidof plymouthd >/dev/null
then
    plymouth_send() {
        [ "$1" = '-n' ] && { # add a flag '>' for lines that will be extended
            shift
            /bin/plymouth message --text=">$*" || true
            return
        }
        [ "$1" = '-w' ] && { # add "warning" formatting
            shift
            /bin/plymouth update --status="warning" || true

log_begin_msg () {
    if [ -z "${1:-}" ]; then
        return 1
    fi

}

As well as adding

   # Only do the fancy stuff if we have an appropriate terminal
    # and if /usr is already mounted
    if log_use_fancy_output; then
        RED=`$TPUT setaf 1`

    else

    fi

    if [ $1 -eq 0 ]; then
        echo "."
        plymouth_send "."
    elif [ $1 -eq 255 ]; then
        /bin/echo -e " ${YELLOW}(warning).${NORMAL}"
        plymouth_send -w " (warning)."
    else

    plymouth_send -n "$@..."
}

log_action_cont_msg () {
    echo -n "$@..."
    plymouth_send -n "$@..."
}

log_action_end_msg () {
    log_action_end_msg_pre "$@"
    if [ -z "${2:-}" ]; then
        end="."
    else
        end=" ($2)."
    fi

    if [ $1 -eq 0 ]; then
        echo "done${end}"
        plymouth_send "done${end}"
    else
        if log_use_fancy_output; then
            RED=`$TPUT setaf 1`
            NORMAL=`$TPUT op`
            /bin/echo -e "${RED}failed${end}${NORMAL}"
        else
            echo "failed${end}"
            plymouth_send -f "failed${end}"
        fi
    fi
    log_action_end_msg_post "$@"
}

So far I wasn't able to get the messages through to Plymouth, but I did get a better understanding of how Plymouth scripting works!

I don't know what else am supposed to do to make it work! hoping somebody here can help me out

Ohh and here is my version of the script for the Splash I am working on.
