I am trying to change the Boot purple screen to black so I searched to find this. I followed the last answer (by heisenberg) saying:

If you don't like the purple screen when you first turn on the computer and want to change it to black.

Here are the instructions to accomplish this.

  1. Open the file /lib/plymouth/themes/ubuntu-logo/ubuntu-logo.script with a text editor
  2. Find the two lines quoted below in the script
  3. Change all the values in the brackets to “0” then save the file

    Window.SetBackgroundTopColor (0.0, 0.00, 0.0); # Nice colour on top of the screen fading to 
    Window.SetBackgroundBottomColor (0.0, 0.00, 0.0); # an equally nice colour on the bottom
  4. Run the following command in the terminal

    sudo update-initramfs -u

The colour of the boot splash background will now be black instead of purple when you reboot.

I've opened the ubuntu-logo.script file with gedit but am unable to save it. Where am i wrong?

  • consider that you can also make an image as a splash screen instead of using nice colours

you have to open the file with root previlege

gksu gedit /lib/plymouth/themes/ubuntu-logo/ubuntu-logo.script

and then change the values and you can save it.

  • what is the color format used there. what is meant by (0.0, 0.00, 0.0). I don't think it is normal RGB values. Because as I know, they cannot be decimal numbers in RGB values? Oct 5 '14 at 6:07

    @SamithaChathuranga The color format is in percentage RGB. colorhexa.com/4dbcff was helpful for me to find the colour I wanted. Example: rgb(0, 159, 255), in percentage rgb(0%,62.4%,100%) means 0.0, 0.62, 1.0 for the ubuntu-logo.script.
