Plymouth themes aren't appearing

Question

I use Ubuntu 16.10. Even though I choose a plymouth theme, still some codes and messages (with green "OK" in every message) are appearing while booting. I updated plymouth theme via sudo update-alternatives --config default.plymouth then sudo update-initramfs -u. I use Intel graphic driver

Answer 1

I spent 2 days research on plymouth and coding, real fun by the way, try this.

Check your possible resolutions with sudo hwinfo --framebuffer and make following entries in sudo nano /etc/default/grub.

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"


GRUB_GFXMODE="1920x1080x32"
GRUB_GFXPAYLOAD_LINUX="keep"
GRUB_VIDEO_BACKEND="vbe"

If the entries are done, run:

sudo update-grub

Test splash with this command:

sudo plymouthd --debug  ; sudo plymouth --show-splash ; for ((I=0;I<10;I++)); do sleep 1 ; sudo plymouth --update=event$I ; done ; sudo plymouth --quit

If you get some splash even just Ubuntu with 4 dumb dots Plymouth is working.

Please also check the entries in your splash theme script file in this example it is ubuntu-sunrise theme, you can use following command with your path to the script file

sudo nano /usr/share/plymouth/themes/ubuntu-sunrise/ubuntu-sunrise.script

There must be 2 entries like this:

Insert the correct paths,

ImageDir=/usr/share/plymouth/themes/yourtheme

ScriptFile=/usr/share/plymouth/themes/yourtheme/yourtheme.script

Finally once more

sudo update-initramfs -u

Reboot.

Answer 2

Edit /etc/default/grub: you need line 9 to read:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

Then run:

sudo update-grub
sudo update-initramfs -u

NOTE: the last step is required when ever you change the plymouth theme.

Answer 3

sudo -H echo FRAMEBUFFER=y > /etc/initramfs-tools/conf.d/splash

sudo update-initramfs -u
