on my Debian box, I have installed Plymouth for a splash screen. I have tried updating the theme but everytime I use the commands:

/usr/sbin/plymouth-set-default-theme myTHEME

and then try to update it with: update-initramfs -u and add the word splash to the /etc/default/grub file and update the grub by: update-grub

the theme i get are simple blue and white bars at the bottom of the screen and the word Debian appears. I've tried changing to the default installed themes and still i have the same theme. Is there something I'm not doing to update it properly?

  • Simple? Is it text mode? Make sure you have a drm driver at boot time.

  • Simple - there's nothing fancy about the blue progress bar. Text Mode- how do I check for that? DRM driver at Boot Time- I guess I can look online for how to check but do you know how? Jan 14, 2014 at 17:23
  • did you update initramfs with sudo first? Mar 28, 2015 at 18:02

I had a similar issue getting the boot splash to change on CentOS 6. After creating a custom theme and initiating the initramfs rebuild, upon reboot the theme had not changed. This was fixed by specifying the VGA mode in the grub configuration file by adding


to the boot line, where (in my case) <code> was 791 for a 16bit 1024x768. You may need to play around with the codes for your platform to get it to work.
