Thank you very much, @LinuxLoverForever!
You did help me by pointing out things that made sense, that allowed me to try the kernel thing. Thank you!
I haven’t attempt your method, as to mark it as a solution (I don’t want to try it out by going “there” again with this nvidia-450xx problem that had annoyed me, frustrated and tired me so much today — and made me relate to this YouTube video: iYWzMvlj2RQ). I would have definitely tried it out before, though, while I still had the issue.
It puzzles me that part of the installs and removes (
mhwd -r, KDE Config etc.) aren’t done with
pacman, even though they seem to operate in the packages…
Once again, thank you so very much!
