How do I change bootvid on Debian 12?

[MrMegarich]

Got it running on Debian 12, how do I change the bootvid?

It's a bit fiddly, I believe you need to:

• Add splash to the kernel parameters in your grub config, and sudo update-grub2
• Select the bootvid theme using sudo update-alternatives --config default.plymouth
• Regen initramfs by doing sudo update-initramfs -u

[MrMegarich]

When I do sudo update-alternatives --config default.plymouth it says "update-alternatives: error: no alternatives for default.plymouth".

[MrMegarich]

Also what's the proper way of adding splash to my grub config

[rozniak]

Sorry I sent that over my lunch break.

Have a read on the Debian wiki, for instance plymouth-set-default-theme is apparently for changing the theme, I thought it was update-alternatives. Maybe that's just for Ubuntu or something, I definitely saw it somewhere!

splash goes in /etc/default/grub - have a look: https://wiki.debian.org/plymouth#Configuration

[MrMegarich]

Do I type --splash or -splash or just splash

[rozniak]

[MrMegarich]

I added the splash option and selected the theme with sudo plymouth-set-default-theme -l but it still shows command line stuff on boot and not the bootvid. And yes I ran sudo plymouth-set-default-theme -R THEME if you're curious.

[rozniak]

Did you sudo update-grub2

[MrMegarich]

Yes.

[MrMegarich]

Hey it's been 4 days, sorry if you are busy but I still haven't been able to figure this out.

[rozniak]

I will have a play in a VM when I have a chance a bit later and get back to you, sorry mate

[rozniak]

@MrMegarich Mine worked:

vim /etc/default/grub # add splash to linux default
plymouth-set-default-theme -R bootvid
update-grub2

[MrMegarich]

That didn't work it still shows the command stuff on start up

[MrMegarich]

I can send you the vm if you want to have a look

[rozniak]

You will need to do some troubleshooting on your own ya know. I'll be busy with stuff irl for a couple weeks so won't really be around all that much.

All I can say is I set up a new Debian 12 VM and did the steps I said and it just worked. idk if you need to apt install plymouth or something silly like that or what, you'll have to investigate it your side.

[MrMegarich]

Ok
