Seems it's fairly easy to make a working solution in initramfs-tools alone, but there's a compromise. If I only include tiny/simple framebuffer drivers in initrd then i915 starts so late that Plymouth doesn't use it, and bug 2054769 can occur on some machines. If I include all the current drm drivers in initrd then it bloats to 100MB, but at least i915 starts early enough (only just) to avoid bug 2054769.
I'm currently leaning toward only including tiny/simple framebuffer drivers and trying to solve bug 2054769 with additional heuristics in Plymouth itself (when the physical monitor dimensions are unknown under simpledrm). If nothing else, fixing this bug is more important than fixing bug 2054769 for all cases. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1970069 Title: Annoying boot messages interfering with splash screen Status in initramfs-tools package in Ubuntu: In Progress Status in linux package in Ubuntu: In Progress Status in plymouth package in Ubuntu: In Progress Status in systemd package in Ubuntu: In Progress Bug description: [ Impact ] Kernel (and systemd) log messages appear during boot for many machines, when the user should be seeing only the BIOS logo and/or Plymouth splash screens. [ Workaround ] On most machines you can hide the problem by using these kernel parameters together: quiet splash loglevel=3 fastboot [ Original Description ] Since upgrading from 20.04.6 Desktop to 22.04, the boot screen is not as clean as it used to be. Basically, the flow used to be in 20.04: GRUB > Splash screen > Login prompt Currently in 22.04: GRUB > Splash screen > Messages (in the attached file) > Splash screen again for a sec > Login prompt All of those messages already existed in 20.04, the difference is that they were not appearing during boot. I was able to get rid of the "usb" related messages by just adding "loglevel=0" in GRUB. Currently is "quiet loglevel=0 splash". Regarding the fsck related message, I can get rid of them by adding "fsck.mode=skip". However, I do not want to just disable fsck or set the loglevel to 0. This is not a sustainable solution. Something definitely changed here. These messages are not of enough relevance to be shown at boot by default, and they should remain hidden like they were in Focal. Obviously a minor issue, but important to the whole look and feel of the OS for desktop.
