NB -- I acted on your original post of 1 hr ago, & posted the results below based on that, only to then see you edited your post 30' ago -- rats. I am now exhausted & stressed out, so will have to leave your new idea [thanks for it] til tomorrow.
===================================================================
I selected Nouveau instead of current Nvidia 367.57, edited & updated grub line to be:
, rebooted [accepting default 47 kernel & normal boot], observed nice high-res full-screen splash-screen, but then that same flash of text came & vanished again, then the blue splash-screen flickered into a black emergency boot screen. I retried a few times, but it always happened.
I had to again use the recovery boot fsck option, but the subsequent plasma login screen, & the desktop session afterwards, were a lousy low-res 1024x768 [or something similar] & i couldn't increase it to my normal 1920x1080. Because the Nouveau driver did NOT fix the normal-boot problem, AND then also gave an additional problem of low-res, i saw no reason to keep using it, so i changed back to my previous Nvidia driver, re-edited grub to:
, rebooted [accepting default 47 kernel & the recovery boot fsck option], logged back in, & plasmashell seems all good again... but i repeat, this is still NOT with a normal boot.
This ongoing stress feels like it should be giving me a stomach ulcer! Unless anyone has any great new ideas, i think i have to give up, & just accept this weird recent bug is unsolvable, & that from now on i must always use the recovery boot fsck option.
