The default Ubuntu Logo plymouth theme has the description "A theme that features a blank background with a logo." Instead of that "blank background" I want to have my own customised image as the background to the same logo with the four dots. I know about the option of installing other plymouth themes, but I specifically want only to change the purple background of the default theme to an image. I am using Ubuntu 19.04 Disco Dingo. Thanks, in advance!

Open the file with below command

sudo -H gedit /usr/share/plymouth/themes/ubuntu-logo/ubuntu-logo.script

look for the content at line no. 192 (Please note that I have already changed line no. 192)

logo.image = Image (logo.jpg);
logo.sprite = Sprite ();
logo.sprite.SetImage (logo.image);
logo.width = logo.image.GetWidth ();
logo.height = logo.image.GetHeight ();
logo.x = Window.GetX () + Window.GetWidth () / 2 - logo.width  / 2;
logo.y = Window.GetY () + Window.GetHeight () / 2 - logo.height;
logo.z = 1000;
logo.sprite.SetX (logo.x);
logo.sprite.SetY (logo.y);
logo.sprite.SetZ (logo.z);
logo.sprite.SetOpacity (1);

at line no. 192 logo.jpg is the Image of my interest and its location must be /usr/share/plymouth/themes/ubuntu-logo/ as described in this file /usr/share/plymouth/themes/ubuntu-logo/ubuntu-logo.plymouth

[Plymouth Theme]
Name=Ubuntu Logo
Description=A theme that features a blank background with a logo.
ModuleName=script

[script]
ImageDir=/usr/share/plymouth/themes/ubuntu-logo
ScriptFile=/usr/share/plymouth/themes/ubuntu-logo/ubuntu-logo.script

enter image description here

After saving the file, run sudo update-initramfs -u and the changes will be effective after a reboot.

  • Did not work. Line 192 of the original script is logo.image = Image(logo_filename) where logo_filename is a variable pointing to the Ubuntu logo file. Replacing this will replace the logo with a wallpaper screen. Not what I am looking for. The replacing did not work either for me. Only a blank purple (default) screen showed up at boot time.

  • OK, if I Understood your question correctly.. you need to work out with images to achieve what you want.. I guess you need ubuntu text and circle with friends logo from ubuntu-logo16.png and then make your own changes and follow this link askubuntu.com/questions/1122675/…
