OK, an update... i've solved it, but i have absolutely no understanding of why this silliness erupted out of the blue today. A further [new, different] dumb fault arose during my subsequent solution, which i've also solved, but it also makes no sense at all. Sigh.
I wondered if somehow the removal of nvidia-prime had also unintentionally damaged the Nvidia graphics driver itself, so in case it had, i decided to:
After that i rebooted, assuming Lappy would have no choice now other than to definitely use the Nouveau driver, which presumably should still work... & it did! I was able to now get all the way through the boot process to the normal log-in screen, log-in, & voila. Stupidly, madly, insanely, inexplicably, now the Network Manager decided it was happy again, hence i had my normal network connectivity back [why on earth did the Nvidia driver get corrupted, & WHY then did that stupid fault then cause the Network Manager to die??? What possible relationship is there between a graphics driver & a network manager?]. Using the Driver Manager i reinstalled the latest Nvidia graphics driver, rebooted, & yay... booted correctly, logged in ok, Nvidia driver was working properly again, Network Manager working again... perfect!
Ah, no, not perfect. Now the new fault occurred... System Monitor / KSysGuard decided it was not happy, & so decided to fall over. Every time i launched it, there was a system error sound, & an error msg popup appeared:
As soon as i acknowledged it, there was another error audio chime, & a new but similar popup:
By now i was quite pissed off [more than half my day had already been wasted by now]. I completely removed ksysguard & two dependencies, reinstalled it/them, launched it... only for the identical symptoms to repeat. Taking note in Dolphin that /home/kdemeoz/.local/share/ksysguard/* had not disappeared when i'd removed ksysguard, i re-removed it & dependencies, manually deleted /home/kdemeoz/.local/share/ksysguard/* , re-reinstalled ksysguard, launched it, & now it was happy -- it ran fine. In Dolphin i noted that /home/kdemeoz/.local/share/ksysguard/* has not been recreated ... huh? --> EDIT - aha, it did reappear the next time i closed ksysguard.
Lappy's Maui now seems to be happy again... but it's now 8 damn hours since i first booted it up this morning... grrrr. To rub salt into the wound, AnyDesk still does not work [which was the entire reason for removing nvidia-prime that initiated this mess today]. Such fun.
