It might be a filesystemcheck running in the background.
Can you disable the splash by pressing escape to see the terminal during boot?
Or can you even remove the splash parameter from the boot lin in grub (Press e on boot entry in grub remove the splash and quiet parameter and hit ctrl+x to boot)
It should give you verbose output on the screen about the boot process.
"It might be a filesystemcheck running in the background. " --> if it is, how can i tell? What can i do about it?
"Can you disable the splash by pressing escape to see the terminal during boot?" --> No, ESC does nothing.
"Press e on boot entry in grub remove the splash and quiet parameter and hit ctrl+x to boot" --> yes this stopped the skyblue Maui splash screen appearing, but instead the screen then just stayed black except for a low-res pixelated rectangular border near the screen edges. Nothing happened after this [& i retried this many times], so i had to re-reboot.
"should give you verbose output on the screen" --> no, it did not, just a mostly black screen as per preceding answer.
Ever since this fault first occurred several hours ago, 100% of the time i now cannot do a normal boot up. The only way now i can boot into eventually a plasmashell & login to get back to a desktop, is to select the kernel Recovery option in the initial boot menu. Whilst this fright was giving me heart attacks, this workaround is at least working each time... so far.
PS - I have now commented-out line 2 of grub file (in case it was conflicting with line 4), & updated grub. It did not help anything, but also does not seem to have made anything worse.
