Plymouth doesn't work

[sjimenezh]

Ubuntu Version: 25.10

Desktop Environment (if applicable):
Example: GNOME, KDE Plasma, XFCE, Budgie, etc.

Problem Description:
When I turn on / off my computer, Plymouth doesn’t work. Instead, I get this:

When I installed Ubuntu, it worked perfectly; but suddenly it stopped working, and it hasn’t worked since. I know it’s a minor problem, and it boots up fine and doesn’t cause any problems; but I would like to have the “normal” boot screen.

Relevant System Information:
HP laptop 14-cf2xxx / Intel GPU + CPU / Linux 6.17.0-14-generic

Instead, I get this:

This is plymouth. – Perhaps not the theme you expected.

check which themes are installed
dpkg -l “plymouth-theme*”

check the log if you removed a plymouth theme
xdg-open /var/log/apt/history.log

try to set another theme as default
sudo update-alternatives --config default.plymouth

Does the system boot OK though? Can you log in and use the system as expected?
