Background image when starting "the feather"

[clunga]

Dear Trinidad, no success  and  you have been so kind that now I will five you the full picture right from the beginning.
In /usr/share/plymouth/themes/mynewtheme1/  there are :

1  mynewtheme1.plymouth which reads

Code:

Plymouth Theme]
Name=mynewtheme1
Description=Wallpaper only
ModuleName=script
[script]
ImageDir=/usr/share/plymouth/themes/mynewtheme1
ScriptFile=/usr/share/plymouth/themes/mynewtheme1/mynewtheme1.script

2  mynewtheme1.script which reads

Code:

wallpaper_image = Image(“splash1.png”);
screen_width = Window.GetWidth();
screen_height = Window.GetHeight();
resized_wallpaper_image = wallpaper_image.Scale(screen_width,screen_height);
wallpaper_sprite = Sprite(resized_wallpaper_image);
wallpaper_sprite = sprite.SetZ(-100);

3 splash1.png ( which is an image with written reminders on some operastions to do)

if type in the terminal

Code:

sudo update-alternatives --config default.plymouth

it opens a lot of choises, but the first is marked with asterisks. I will show you the first lines:

Code:

There are 21 choices for the alternative default.plymouth (providing /usr/share/plymouth/themes/default.plymouth).

  Selection    Path                                                           Priority   Status
------------------------------------------------------------
* 0            /usr/share/plymouth/themes/mynewtheme1/mynewtheme1.plymouth     100       auto mode

Now let us describe what happens.
The desktop starts in multibooting, with the grub residing  in linux mint showing the 4 distros to choose.
the first is Rocking Hoss Transformation Linux Lite 64 v.3.6.1 and I choose it.
The mint splash page remains up for 6 or 8 seconds thant after a black screen for 2 seconds, these writing appear on the top in small white characters :
3.214526] [drm·intel_enable lvds  etc
3.761835] sd 6:0:0:0: [sda no caching mode
3.761886]sd  6:0:0:0: [sda]Assuming drive  et.
11.7786821 ata1:  COMRESET failed  (errno=16  and it repeats 3 times, ( I suppose it is due to the fact that my notebook has a SDD not working and I work only on external HDD on usb port)
After 5 or 6 seconds I have a black screen and I understand someway it is an image, so if I press ESC I have a lot of commands rolling down with a green ok when completed ,  up to the point when  the screen is again black and an image appears, which is the one I have set up possibly  somewhere in light boot to be the background , alternating it to the logo feather image, even if I have changed it it  in plymouth, most likely lite boot. A few second and finally the white login page with the linux icon where to digit the passwword  and then the welcoming message that I have personalized editing the .wav.
Thanks for your assistance.
