Booting a Lubuntu QA-test installed system (2020-04-11 ISO installed today) and after plymouth, I briefly see the VAIO logo before the sddm greeter occurs. Order I see is (3 boots to confirm) - encryption-key-screen - vaio - plymouth (lubuntu dots) - vaio - sddm/greeter the vaio screen appears also on shutdown...

I tried to rootcause my flicker over the last few days, it was definitely not due to the kernel and neither due to plymouth (tried by installing the respective packages from focal in eon and vice versa in focal). One thing I wanted to try next was initramfs but did not have the time to test.

There will always be cases where grub needs to display a menu, in which case it's going to change the background.

This is an improvement! Previously, during that time period the whole display (at least on laptops) would be powered off and people saw a temporary backlight flicker. With this in place we might be able to to implement a flickerfree boot! I will double check what we need to change in the theme to ensure our boot now has less flicker.

[Kernel-packages] [Bug 1861470] Re: BIOS logo reappears mid-boot after the purple screen
@vanvugt Coming from the other bug report I'm trying to describe my problem: First of all I don't see purple as I have disabled the purple grub by running chmod -x /etc/grub.d/05_debian_theme Secondly: In Ubuntu 19.10 there is no flicker happening for me, while in Ubuntu 20.04 there is a flicker. Why is that? There must be something in 19.10 that is not part of 20.04. In Ubuntu 20.04 the bios logo appears after grub, then it flickers just before the spinner shortly (during the flicker a white cursor appears on the upper left corner of the screen), you can see this here: https://youtu.be/O_Efd9szFFI during second 6 and second 7 (in reality it's much better noticeable than on the video).
