Hi all,
I was wondering if it was possible - and how - to personalize the logo (splash screen? not sure) that appears as soon as the system is booting on my laptop.
There are two startup screens you might be referring to here.
The first only appears if youāre using full-disk (LUKS) encryption and looks like the image on the left. This is a Plymouth customization which ublue have done, and you can change it by installing a different Plymouth theme.
The second is for the user login screen and looks like the image on the right. This is a customization to the GNOME login, so thatās what youād have to change in this case.
Depending on which one you want to change/customize, there are different solutions. If you want to change both, youāll need to apply both solutions.
But now that youāve asked, I am curious about it, so Iām going to try out a few changes myself to see what itās like. Could you let me know which one you meant, or if you meant both? Iāll then post a follow-up reply later, after Iāve tried out a few things (assuming Iām happy with my changes).
Hi, thank you kindly for answering 
I meant the first image in particular.
With my MSI laptop, the following happens with any GNU/Linux system I use: the MSI logo appears when booting, but also on the bottom side another Linux logo appears (Ubuntu, openSUSE, etc.).
Iād like to change that first logo you showed with another one if possible. I was even thinking about the āUniversal Blueā one or something similar, like the one we have on the top left corner of the GNOME desktop.
Iām loving the dinosaurs, but I prefer something further āenterprise-lookingā when Iām at the office.
i also have to agree with this, the dinosaurs dosnt make the distro feel professional, sorry
In the meantime, Iāve played around with it a bit.
In default Fedora, there are a few plymouth themes pre-installed. U-Blue seem to have only properly included one of them - the spinner theme - and theyāve changed the Fedora logo to the Bluefin logo, as per the location in this screenshot. You can see how theyāve worked directly with Fedora Silverblue by keeping the image names the same.
Other locations > usr/share/plymouth/themes/spinner
If you look at the other folders in the āthemesā folder, they havenāt included the necessary files.
There are three options here.
- Change the pre-installed customization by replacing the Bluefin logo in this folder with something else, but it must have the same name. This is a pain in the ass, as the immutability/atomicity means that you donāt have sudo access here. The files are intended to be read-only, so it would take a bit of work to get around that.
- Repair one of the other plymouth themes and assign that as the default one.
- Install a different plymouth theme from the beginning, and set that as the default one. Iāve done that to try it out and it works ok.
Background information on how to do this on normal fedora is here: https://www.makeuseof.com/how-to-change-fedora-splash-screen/
But on Bluefin, youād have to use rpm-ostree as a command.
With any of these options, youād have to update initramfs afterwards, to make your changes take effect.
In short, there is no easy way to do it. Any approach involves trying to get around how ublue have set it up. They donāt want someone to change the splash screen appearance, but I think they should make it easier. The dinosaur isnāt something Iād want to ever show anyone when starting my computer, and I donāt want to look at it every time I start my computer either. I have an Aurora install as well, and the Aurora logo looks much more professional.

Bind mount whatever image you want over the watermark image.
Then make a local initramfs with rpm-ostree initramfs
This could work. I believe the bind mount will propagate.

Unfortunately binding the picture makes the OS not bootable, despite the initramfs and all. I could easily revert the situation.
By the way, rpm-ostree initramfs --enable is the correct command apparently.
Well, I tried
