Plymouth splash screen vanished

Linux Mint 21 Vanessa base: Ubuntu 22.04 jammy.

I have a duel boot system with windows 10. I had problems with GRUB which has been sorted out. However, now when booting I see lines of code instead of the splash screen.

cjhm@CJHM:~$ update-alternatives --query default.plymouth
Name: default.plymouth
Link: /usr/share/plymouth/themes/default.plymouth
Status: auto

Any assistance on how to get the splash screen back welcome.

Hi Tramlink,

Did you try reinstalling the plymouth package, maybe something like;

sudo apt-get install --reinstall plymouth-theme-mint-logo

(I don’t know the actual package name as I don’t have a mint handy, but all the other spins I have seem to follow this naming convention, confirm with sudo apt search plymouth)

I’m not sure what specifically would be broken, but my expectation would be that a re-install of the package should put it back and rebuild the appropriate bits without having to resort to rebuilding low-level stuff by hand.

This is still an on going issue after a reinstall and many hours trying the options offered on the web.

And yet still get lines of code when booting and showing the code seems to make the boot process takes longer.

All the information in the configure files point to mint X.

Ok, so the “lines of code” are likely something a bit different. When you boot a Linux system, if you “know” it’s going to work, then a Splash screen is usually what you want to see. If on the other hand you’re expecting a problem, it can be useful to see what’s going on with regards to diagnosing the problem.

If this is what you’re seeing, then typically this is a lack of the “quiet” option in your boot config.

If you have a look (not this varies, but typically) in /boot/grub/grub.conf , or grub.conf somewhere under /boot, then either directly within this file, or within a file it “includes”, you will find the lines used to select and activate the Linux kernel.

The two lines are usually adjacent and start …

linux /boot/...
initrd /boot/...

Now the “linux” line will have a number of “options” after it. To get a splash screen and no debug messages you need to have the words “spash” and “quiet”. So for example;

linux /boot/vmlinuz-4.15.0-87-generic ro splash quiet 
initrd /boot/initrd.img-4.15.0-87-generic

Assuming one or both of these are missing, if you add them and them reboot it “should” make a difference … not sure why this would be missing tho’ it you’ve reinstalled. Typically if it’s in quiet/splash mode it’s only going to spit out debug if it hits a problem while booting …

HI, “splash quiet” was missing from the end of the line of code.

I replaced this and the boot splash screen is restored.

Thanks for your help.
